Montroyalite… ever heard of it?
This is the mystery object for this week’s post, and our mission is to discover what it is. It is a game accessible for the all VC readers, including the ones with a limited knowledge of volcanology, geology or petrology. You know it’s name. Now the goal is to find the facts about it. What is it? Where does it come from? How old or young is it? How was it formed? What does it look like? What’s its formula? We want to know all about it : the what, where, why, when, who and how. And more.
With its name, anybody can become a detective, and the more knowledgeable readers can confirm or expand on what we find.
So it is up to you to post your discoveries, and at the end of the game, we will summarize our findings about this mysterious object.
Let’s see who can post the most facts about it.
Summer
UPDATE
What is life without a riddle. This time it is me who is fiendish.
I am the stony product of music that make Pavarotti mate a canis canis sheep mixture, I am spawned out of the apothecary.
What am I? And what is my origin?
CARL
This post opens the normal weekend-ly Sheepy Dalek.
I like Summers idea, but i will not be here to do the summing up.
Please keep posting informations about the current eruption of Fuego. And if this has already been posted, don’t worry, post it again. Things get lost in old threads easily.
For those who have not been around the last few days, please go back one post and read GeoLurkings excellent post about Icelands “Dead Zone”
Stay safe while i am on vacation. I am looking forward to the holiday but i will most certainly miss the blog. Posts by Bobbie KarenZ and Talla are waiting to be published next week but posts about news are now up for Carl or other dragons. “I ll be back” *wave*
@Spica: Have a dragonish good flight and ENJOY!
Have a safe trip and maybe, maybe watch the birth of Bobette from Tenerife!
Have a wonderful holiday, Spica! Tell us all about it when you get back. 😀
Thanks for the wishes All, yes you can expect at least one post about it with tons of pics. And now i am really out of the door or i ll be late.

have a good volcanofiliac holiday ! I bet you will get samples…
Montroyalite is a mineral, discovered in Montreal, named after Mount Royal, the mountain which provided the definition sample (wikipedia)
The chemical formula is Sr4Al8(CO3)3(OH,F)26•10-11(H2O)
Its molecular Weight = 1,384.60 gm
and it consists of:
Strontium 25.31 % Sr
Aluminum 15.59 % Al
Hydrogen 2.48 % H
Carbon 2.60 % C
Oxygen 37.55 % O
Fluorine 16.47 % F
(webmineral.com)
Just to educate a bit.
The percentages are by weight, not amount of atoms or volume.
Strontium is much heavier than aluminium, that is why the 8 aluminium atoms get severely less percentage then the 4 Strontiums.
Also, this is one of the ores (minerals) that you should not build your house out of, of for that matter eat. Strontium is both radioactive and poisonous. Same goes for the high fluorine content. Fluorine is not radioactive, but it is not good for your health at those levels.
Montroyalite, discovered 1985 (http://www.mindat.org/min-2770.html), was born 125 million years ago in a pluton which was later unearthed to become Mount Royal (http://www.nrcan.gc.ca/earth-sciences/products-services/mapping-product/geoscape/montreal/6197).
Nice idea, Summer, fun research without competition.
I put in an Update to the post…
This Riddle should have made even Alan cry in his yellow coverall in pure joy 🙂
3 points to have… A hidden 4th point is also there if someone get the small corny fact that is also clued in…
that’s a wicked riddle Carl. So far I have got tenor, sheepdog and pharmacist and it’s starting to itch.
There’s a salve for that.
I’ve got it, it’s the Colli Albani!
oh well, perhaps not.
Or a pot calling kettle black?
I am rubbish at riddles……
And in a far away country filled with volcanoes one of the volcanoes did not wake up on it’s best side today.
At 06.29 this morning an earthquake M1.2 happened south of Hekla. After that tremor with harmonic components have been ongoing at Mjoaskerd SIL.
http://hraun.vedur.is/ja/hekla/oroi_mjo.html
At roughly ten o’clock there was a sudden increase at negative strain at Hekla.
http://hraun.vedur.is/ja/hekla/thensla_hekla.html
Interesting.
Yupp. Defenetly. Shure. Humm… What the heck etc.
That is highly unusual.
And Mila Hvolsvöllur webcam is back online,
please turn 45 Deg left ( 😉 )
For the non-regulars.
Hekla has a history of giving very little warning before erupting. The last one had seismic activity start about 61 minutes before eruption, and the quakes only got to the level of human perception about 10 to 15 minutes before it went. Provided that you were standing on top of it. (else you never would have felt it)
Hekla is dangerous.
Is that quake in the Vatnafjoll system?
Yes, and MJO SIL is at west end of the mountain ridge. Technically not Hekla, but there is catch. Larger lavas have run in area south and south east of Hekla, than from Hekla itself. Very large eruption in Vatnafjöll area is needed for lava to enter farmlands (apx runs of 10 – 15 km or more) so little imminent danger really, I think. Some ash, black and heavy stuff. No concern for air-traffic in long run.
….Where is Irpsit trekking to this weekend? I hope not round Miss Hekla!!!
amend: , than from Hekla itself to the north. Most Hekla lavas ran to south/south east in recent eruptions (except Skjólkvíjar 1970; technically).
nah, think Torfajökull area. Hope he took clean bags for ash samples 😉 Not expecting anything, but unrest at Mjóskarð continues. I am watching this.
I am joining you….. have a mug of mulled wine on me!! 😀
*Thank you! Not really trusting one single SIL (but this one has behaved well all summer) but the unrest continiues at MJO. Checking winds and windspped on Vegagerð roadcams, winds are several directions, and Low pressure area is passing. Windy and drizzle all over the area could account for some of this, but seems more, and spiky on other graph I am watching. So far no more quakes. If one appears in Hekla proper I am off to there. But we must not stir the press, probably all is well in Hekla innards.
oh my, from Eruptions… (i was trying my best to spread the sheep meme).. a certain mafla just posted this… picture of the year. What do you think, sub-plinian for sure, vulcanian or just plain Dorset?

No. Its a movie. “Silence of the Lambs” remake Snow-Lamb*(TM)
ha. I once had the idea of doing a very English style of catastrophe movie called Dante’s Bottom. … I think I’ll stop now before I go any further.
You could probably get Kevin Smith interested. His View Askewniverse series has a character named Dante Hicks. (“Jay and Silent Bob” movies “Dogma” and “Clerks”).

“Some tourist guidebooks, such as the Michelin Guide to Montreal, state that Mount Royal is an extinct volcano. The mountain is not a traditional volcano as such. However, it is the deep extension of a vastly eroded ancient volcanic complex, which was probably active about 125 million years ago.”
So as not to copy too much, here is the link with the interesting details: hotspot, intrusion, magma, gabbros, etc. See the geology paragraph:
http://en.wikipedia.org/wiki/Mount_Royal
Also from the link: “The mineral montroyalite, discovered in Montreal, is named after the mountain that provided the definition sample.”

Its looks as if the eqs are reprising the 2011 sequence. The most recent have been in the same position as the second swarm in 2011, the deep one. Very well organised magma to follow the same sequence, shallow, deep……
Yup, it is more lively today ! I’ll try to do some plots, but at the moment I am (well the puter is) working on some plots just prior to the 2011 eruption
Montréal has a connection to African volcanoes:
“[There is] a long-distance and long-lived hotspot chain that extends from Canada to undersea volcanoes on the African tectonic plate. The volcanic activity that formed this long chain provides a history of how the North American and African plates have been moving for over 100 million years.”
“The Monteregian Hills, which share a name with the city of Montréal in Québec, Canada, are the eroded remnants of volcanoes that are the oldest volcanoes of the hotspot track: they were active about 125 million years ago.”

Happy Friday All,
My guess for the phantom dinger is Ukviggen, he’s on the board for his local Rugby Club…
Has that been guessed already?
Off on holidays myself; we’ve a week in Napoli starting Monday; so pizza, Vesuvius, Campi Phlegrei, Ischia, Pompei, Herculaneum; Lizzie fancies the Amalfi Coast, are we missing anything?
Hi schteve
lucky man !
Paestum south of Sorrente and the Amalfitan coast, if you like greek temples, there’s a nice bunch there.

Have fun Schteve.
Enjoy. I recommend going to Solfatara. It stinks but it’s the wierdest feeling walking over a crater. You can feel the stuff beneath moving!!! Scary…ish http://en.wikipedia.org/wiki/Solfatara_(volcano)
I am just a tad jealous of both you and Spica. It looks like Bobbette is trying to gain her attention!
G’night All x And Fanx x
I suggested ukviggen too, but I don’t think anyone actually revealed the mysterious dinger’s identity yet…
I confess. I think Ursula named me within about two minutes of someone asking the question, and it just seemed like fun to keep it going.
The ‘rugby management meeting’ was the weekly meeting of the team’s coaches/admin as they plan strategy for the weekend’s game. It is normally held on a Friday in a suitable venue out in the country that serves occasional refreshments. Most of us drive there, and then have to go back in the morning to retrieve our cars.
Have fun in Naples!
Oops, didn’t see above. By the way Ursula, I really thought you were going to get the savoury ‘fruit’ when you started mentioning the Tomattini (sp?) from Santorini – very similar idea to the Arancini
I still think the Sicilian Frutti di Mari should have merrited a point 🙂
But since nobody guessed it…

Hi
As things are a bit more lively today in El Hierro, here is the updated earthquake density video up to today.
http://eruptionelhierro.blogspot.fr/2012/09/update-on-density-plotting-el-hierro.html
I have added the summary for density between july and september 14th at the end.
dfm,
Interesting to compare the summary plot with ‘Daniels’ horizontal GPS plot for the 2012 swarm:
Peter
Hi Peter
I’m not forgetting you, just plotting the VS/VP before 2011 eruption. Takes time….
This picture is up to july it would be interesting to get it updated…
Hi Peter,
I remember that’n, good schtuff,
OK, it’s just one (of many possible) interpretations o’ the data, but it shows (in my opinion) a deep mantle plume source…
Back in 1971 (I wasn’t even a glint then…) Teneguia went off; photogenicaly but safely…
The next real action at the Canaries is 40 years later 100kms south of Teneguia at BoB.
The plot you reference implies a “focus” south of El Hierro; which suggests (to me; Schtrictly Amateur) a “wide-ranging” mantleplume…
Peter, I’m still keen to see your article bout El Hierro, please would you ask the dragons to forward it.
Hi Schteve
Just do not miss the temples at Paestum
Schteve -hopefully Carl will read this and send it you – its in his email. beware – it is highly speculative!
If it schtimulates debate I’m all in favour 😀
Thanks Peter.
Schteve, oh it would do that !! (and probably heap ridicule on me). I think maybe its a bit too off the wall for carl to contamplate posting – bearing in mind 1million visits here etc. Essentially I dont think its magma pressure/ intrusion for the plume thats generating the eqs and GPS motion.
Actually Peter I had decided to post it, but then real life hit me like an 18-wheeler truck setting a landspeed world record…
It is ‘a commin’, especially now that El Hierro is getting frisky.
Thanks Carl, I’ll keep my powder dry to defend it against the hoardes of sceptics!
Land speed record?? – here’s such a car from 1905, on a hillclimb:
-and being driven home afterwards, number plates fitted:
sorry, no trucks. But I expect I shall see that Darraqc again tomorrow!
I’m guessing Cristobalite For carl’s riddle, since it’s found in volcanic ash as tiny sharp chrystals, and if Pavarotti inhaled this, He’d probably sound like a wolfwolfsheep….

It may be too late,
but @ Spica, if you fancy seing a grand performance in a magnificent concert hall:
http://www.auditoriodetenerife.com/en
It’s worth checking the programme;
The Tenerife Symphony Orchestra is world class, ifn they’re playing, it’s worth going… and I think their home season is now ish…
Me and Dad saw them do La Valse by Ravel in the concert hall; the piece is as underated as the composer, I didn’t know whether to laugh or cry… 🙂
Once again @ all; I don’t work for the Canarian tourist board 😀
Montroyalite is an strontium aluminium hyrdrocarbonate: Sr4Al8(CO3)3(OH,F)26• 10-11H2O from the Francon quarry, Montréal, Québec, Canada (address: 3701 rue Jarry Est, Montréal). The quarry has not been mined since 1981.
Mount Royal is an alkaline intrusion into limestone. The dawsonite-rich carbonatite sills of the Francon quarry have a rather unique mineralogy, not found anywhere else in the region. (Source Mindat: http://www.mindat.org/loc-597.html). The instrusion is part of a volcanic complex that was active 125 million years ago.
The complex was formed when the North American Plate moved westward over the New England hotspot. The main rock type is a gabbro composed of pyroxene, olivine and variable amounts of plagioclase. During and after the main stage of intrusion, the gabbros and surrounding rocks were intruded by a series of volcanic dikes and sills. Subsequently, the surrounding softer sedimentary rock was eroded, leaving behind the resistant igneous rock that forms the mountain. (Source: Wiki)

That is a Harmonic tremor , i think , Magma on the move somewhere.
could well be
Probably where those deep eqs are at ca 17km.? (Otherwise it would be a bit coincidental that the eqs move deeper just as tremor starts).
not necessarily, but let’s not be hasty, it’s pretty dim for now, we do not have the red lower band
If this carries on, then tomorrow may see 3.0 ‘s at 20km and more, smaller, eq’s above 10km, like we had before Bob was born last year. It appears that, after the 2.6 this morning, the quakes seem to have gone deeper and stronger again.
And from: “Montroyalite, a New Sr-Al Hydrocarbonate from Francon quarry, Montreal, Quebec” by John L Jambor, Ann P Sabina, Robert A Ramik and B Darko Sturman published in the Canadian Minerologist Vol 28, pp 147- 153 (1990)
“Montroyalite ( SraAls(CO3)3[(OH),F]26.10-11H2O), occurs as translucent white l-mm-sized hemispheres in cavities in a silicocarbonatite sill exposed at the Francon quarry, Montreal, Quebec. Major associated minerals are: albite, quartz, strontiodresserite, calcite, dawsonite, ankerite and fluorite.
Montroyalite hemispheres have a dull surface and a porcelaneous interior with a waxy lustre. Indistinct fibres radiate from the core and produce rough to botryoidal ofierior surfaces. Individual grains are irregular to lath-shaped, up to 0.02 mm long and 0,005 mm thick. The mineral is brittle; it has a white streak, Mohs hardness of 3%, uneven to splintery fracture, no observable cleavage; it is soluble in 1:1 HCI at room temperature (20C), and fluoresces white under both long- and shortwave ultraviolet light. D(meas.) 2.677 g/cml. ”
There is more but it gets too techie for a Friday night in the bar.
Can’t paste the link but found it on Google Scholar searching on Montroyalite.
It also has a friend: Voggite.
Ingrid Parpracen is reporting vibrations at Los Toscas Frontera.
If it looks like things are going to kick off again my daughter has promised to get me to the Island no matter what it takes, and this time im going to make sure i travel to the Airport in an Armoured Personel Carrier, i want to make good my promise of good information and Photos of all that happens so that we can keep a really good record of all that takes place, lets keep our fingers crossed.
Would love to hear you make it there one day soon grimmster. Sounds like you have a lovely daughter.
I second the APC idea. I’d take you in an Mi-24, but I only flew those in a game. (quite well though, usually my gunner complained about being under the terrain and not having anything to shoot at. I tended to fly quite low and fast.)

How do you access those stations ?
change the name in the upper bar : chie to cjul (not in tabs)
NO dont tell me – I’ve got it – dont want flood IGN’s server!
too late! many thanks dfm – perhaps a dragon should delete?
By changing the web bar. For example where you see cjul in the one above? you can change that to corc or any other ones not readily accessible. The key is to make sure you do not use capital letters.
I’m way too slow! 🙂
Bobbi – Slow? n matter. I know the meaning of slow – had to follow Eyjaf on 28k dial up! Peter
one good point to have had a geek son is that he left some infrastructure. I do like my optical fiber…
We are very lucky here in N Wales to have local computer store whose owner has masters in digital comms. So he built us a point-to-point wireless link, capacity 180Mbps, we use a fraction of it, shared with neighbours.
broadband should be a civil right !

Volcanic Association (From Wiki.) Some tourist guidebooks, such as the Michelin Guide to Montreal, state that Mount Royal is an extinct volcano. The mountain is not a traditional volcano as such. However, it is the deep extension of a vastly eroded ancient volcanic complex, which was probably active about 125 million years ago.[1] The mountain was created when the North American Plate moved westward over the New England hotspot,[1] along with the other mountains of the Monteregian Hills, by a process known as intrusion: The magma intruded into the sedimentary rocks underneath the area, producing at least eight igneous stocks. The main rock type is a gabbro composed of pyroxene, olivine and variable amounts of plagioclase. During and after the main stage of intrusion, the gabbros and surrounding rocks were intruded by a series of volcanic dikes and sills. Subsequently, the surrounding softer sedimentary rock was eroded, leaving behind the resistant igneous rock that forms the mountain.
The mineral montroyalite, discovered in Montreal, is named after the mountain that provided the definition sample
The quarry that mined the stone is now no longer worked and is located in the city proper. many of the older buildings are constructed from rock from this quarry . The rocks were also used for roadstone and in the construction of the railroads.
This quarry called the Francon Quarry, Montreal, Quebec, Canada is a one-of-a-kind carbonatite igneous intrusion which has produced several wonderful and unique specimens of exotic species alonside montryalite such as the famous weloganite as well as dawsonite, dresserite, franconite, hydrodresserite, strontiodresserite, sabinaite, cryolite, strontianite and more.
Why is this quarry so unique? It is because of how the rocks cooled and the composition of the intrusive material.
The Francon quarry exposes a rare carbonatite sill. The sill, a horizontal intrusion into parallel host rocks, is composed of carbonate minerals, mostly calcite. The Francon Quarry has produced a number of rare carbonate minerals besides montroyalite such as strontianite and dawsonite. Carbonatite is an igneous rock and is not all that well understood by geologists.
Like other igneous rocks, the carbonatite starts as a molten body, but is composed of carbonates instead of silicates. Like other igneous rocks, carbonatites will crystallize the minerals that are more stable at higher temperatures and pressures first, leaving difficult elements in the left over melt. Difficult elements are those elements that because of their size and/or charge do not fit well into a mineral’s structure and are therefore excluded by most minerals. These elements, like strontium and zirconium, are left to form whatever minerals they can get into as the last bit of crystallization takes place.
In the case of montroyalite, the sill had already formed most of its minerals when fluids rich in difficult elements and volatile gases rose to the top of the sill and formed bubbles or pockets. When the excavations at the Francon Quarry uncovered the sill, these “petrified” bubbles were found coated in exotic minerals some of which were never before known to science. It is believed that this unusual sill was somehow allowed to cool much more slowly than other carbonatite sills. It is the time to differentiate the difficult elements that may have made the difference in producing these unique minerals. Other carbonatite sills have similar chemistries to the Francon Quarry sill but the difficult elements are incorporated into commoner minerals as trace elements.
Oh my…
I think we just had that little competition bumped off. 🙂
Carbonatite, nature easy to tell you “hey I can play with thermodynamics too “

El Hierro is erupting! Look at the graphs!
Do you mean these graphs Renato?

Armand is watching the developments:

Santorini is showing some activity too. Yesterday an unusual quake was a 2.5 at 80km depth. Typically quakes around the Aegean tend to be less than 12km deep.

No official report, at least from AVCAN people. And I must go out now. This is exciting. Or Bob is back, or Bobette is coming to the worl in some other place!
Definitely something going on. Though the freqs aren’t really low, there is banding in the spectra. (HT)
Strongest out by CJUL.
Looks like degassing judging from the frequency.
But there should be no degassing at that depth.
Might be worth while to stay away from the cave entrances.
See below…
It seems like El Hierro is up and about again.
What I find interesting is that there is no movement yet on the GPS:ses, but something tells me that there will be shortly.
Either something is moving up through some tube and an eruption is starting or going to start very soon. Or this is the long heralded arrival of the fourth magma blob. We will most likely know very shortly.
But, as this is at the Tanganasoga site at the usual depth I guess this is a new blob of magma.
To take people through the stages.
1. Blob of magma caused Bob to erupt after months of earthquakes. The inflation never drained away, so that magma is mainly there still.
2. A smaller second blob of magma revigorated Bob in late January early february.
3. The largest of the Blobs arrived in June, it inflated the island with a 9 centimeters of magma, against all ods it never erupted. Combined uplift after the third blob is 14 centimeters.
4. Potentially today a fourth blob arrived.
CCUM is weak, it’s not Tanganasoga. It’s further west.Restored by VC. When you trash things with follow up comments it wreaks havoc to the subsequent posts. Take a look at what happened to the time order of two of my comments below. 22.41 comment was put in before my 22.32 comment.
If someone have written allready I just empty out the comment.
Okay then I retract it until I have better data.
I wanted emphasis, but bold makes it look like I’m yelling, which wasn’t intended.
I meant the quakes… Those are slap bang under T.
But earlier today there was some commotion out in the sea to the NW of Tanganasoga. Juicy deep quakes are though at the usual place.
HT is somewhere west as you say.
ah ah ! very different patterns compared to last time. Bob has plenty in store to surprise us.
Released from the Dungeons by VC, have no clue how this happened.
And the above trashing is what put this one in the Dungeon most likely… Hard to answer to what is trashed.
Bit like London buses these blobs – none for 200 years then 4 arrive at once.
Not according to Lloyd’s of London.
There was most likely an eruptive episode further out of Bob between 1946 and 1948 according to sea captains that reported Jacuzzis south of El Hierro. Life was better when there was tramp steamers going everywhere.
That is interesting. Presumably no eq swarms then as locals would have felt them (despite lack of seismometers) ?
Probably a lot of them, but nobody back then cared.
We should though remember that the swarms we have seen now have been really small, and with the exception of the above 3s nobody on the island would most likely have cared to write it down back then.
People back then did not get hysterical on Fezbook, they had actual lives.
Someone has commented that this is the worry this is happening near CJUL because of the slab of rock perched next to the sea?
CJUL is just bad all the way around. That’s close to Tanganasoga, the dominant vent. Humilladeros is the other one west of there.
So could something break out at Tanganasoga?
Most likely not. I think that one is the most clogged up part of the Island. I think there will be things shooting out of one of all of those swizz cheeze holes that the island is riddled with.
Glad I don’t live on that island right now.
And nobody is even close on the Riddle.
Henrik would have blown it out of the water in about 10 seconds.
For those wondering, Henrik is fine, just busy 🙂
Did he cheer up a little when he saw the taxi video?
I do not know, I think he is resting from VC right now due to real life thingies.
I think the guests at Balneria Pozo del Salud might be getting a huge surprise around come morning…
For those who have missed it, it is the hotsprings bath at El Hierro.
The new swarm is east of Tanganasoga, originating about where June-Blob started, now going off at a different direction, where almost nothing happened so far. Dipping down about the same angle as the 2011 deep swarm. Here is the top view. Video is life in a moment.
There it is:
Aaargh, I planned to sleep early, can trash that idea now… 😉
According to IGN 38 earthquakes as of 21:36. 17 between 2 and 3 mblg, what could be expected from the depth they are mostly occurring, based on the previous swarms.
IMHO I would say this is fresh magma, look at the speed the swarm is expanding, like June this year.
Double whammy I think…
I just feel a post comming bubbling out of my system here… 🙂
“I just feel a post comming bubbling out of my system here…”
I thought so too, but then realised it was just the danish beer…:/
😀
ROTFLOL!
Danish beer is not good for the system… had a Lapin or 3 in the sauna…
I’d recommend Karhu with sauna 😉
While I go for a write up… Something to ruminate on.
Ever wonder where Hurricane Leslie got at?
It became a tropical storm that slowly ambled over the Atlantic turning into a extra-tropical storm around Iceland and then it happily wobbled onwards and hit Norway. As it went over the mountains it did what extra-tropical storms do. They die while happily dumping on me.
The thing with extra-tropicals is that they contain equal or even more amounts of rain than they did when they where hurricanes, but they have lost their windspeed oompf.
So, I am just suffering from a little blow, and a lot of dumping. It is not a good day to take a walk outside. Not at all…
And the order of the post got normal again when i un-trashed the comment above…
So for anyone still finding things a bit slow today I just felt I had to share this wonderful link:
Click to access FGS-2003-June.pdf
Possibly even one for the treasury, Carl?
I was looking around on’t’internet for info about the area of Portugal around Sagres, where the cliff-tops felt like walking on pumice. I didn’t find the pumice but I found the volcanic origins of the area, dating back to the opening of the Atlantic, and magnetic anomalies which reverse compasses, and hot springs up in the mountains.
Detailed geological history of the region is in this link which also includes other geological gems.
I had never heard of montmorillonite before either: ‘The chemical composition of pure Fuller’s Earth [cat litter] consists almost entirely of montmorillonite, a clay mineral with a layer structure, which gives it its absorption properties. It is generally believed that montmorillonite is formed by the decomposition of volcanic tuffs and basic igneous rocks.’
Montmorillonite has been used in water softening before the invention of syntethic resins after WW2. Pretty interesting mineral. It has natural ion excahnge properties.
New post is up!
I am the stony product of music that make Pavarotti mate a canis canis sheep mixture, I am spawned out of the apothecary.
Drug music could possibly inspire people to do unpredictable thingies. The apothecary = the drugman.
Spawned out of the drugman? The mineral Drugmanite.
Webmineral.com: Formed at low temperatures in vugs in mineralized limestones, an oxidation product of disseminated sulfides. Location: Found in silicified karst deposits, Richelle (near Visé), 15 km north of Liege, Belgium .
But left out the part of the canis canis sheep mix… 😉
But it is always nice to learn that Drugmanite emanates from vugs. Now going to learn about vugs…
Pavarotti mating a canis canis sheep was a rather unpredictable behaviour to me… drug related? Now I’ll search for the ccs.
Here it is: http://www.dailymail.co.uk/sciencetech/article-1369977/Sheep-gives-birth-dog-Chinese-farm-Ewe-got-kidding.html
Guess at the riddle – Arsenic (play /ˈɑrsɨnɪk/ AR-sə-nik) is a chemical element with symbol As and atomic number 33. Arsenic occurs in many minerals, usually in conjunction with sulfur and metals, and also as a pure elemental crystal. It was first documented by Albertus Magnus in 1250.[5] Arsenic is a metalloid. It can exist in various allotropes, although only the gray form has important use in industry. (Wiki)
Arsenic – canis and aries mixed up. Opera – Arsenic and old lace. Small amounts of Arsenic can increase the risk of pancreatic cancer which is what Pavarotti died of.
Riddle answer from me…..
Wolframite
Wolf (Canis ) Ram (a male sheep) The naming of this of this mineral is ascribed to Johan Gottschalk Wallerius in 1747
Later it was found the mineral contained a new element “Tungsten”. This name is derived from the two swedish words Tung=Hard Sten=Stone
This new element was discovered by the Spanish brothers José and Fausto Elhuyar who were chemists (Apothacaries).
This gives a weak link to Pavarotti one of “The Three Tenors” Pavaotti’s mate (Friend) José Careras also Spanish. Faust was an opera by Gounod in which Pavarotti and Jose would have both performed.
Wolf is Canis lupus not sure why the double canis bit unless is is a wolf in sheep’s clothing to fool us all!!!
Oh and an interesting fact about Tungsten.F or most animals Tungstan is not good. Tungsten in the soil will inhibit earthworms to reproduce. (I wonder if there are any worms in central Montreal near the site of the mine!!!!!) Excess Tungstan is not tolerated by most living things. However some bacteria especially in soil need tungstan to servive as it is an essential trace element in an enzyme that helps control their metabolism
servive?? :oops Survive
This came when I duckduckgoed the double dog: http://www.ign.com/wikis/beyond-good-evil-hd/Canis_Canis
And the website’s name is IGN!
🙂
………..And Bobbette sayeth………..”Let me out! Let meout!”…..
Seriously the sound of El Hierro below ground….Fascinating stuff..

My thanks to Avecan for their spot- on up-to-date information as it is happening.
“I am the stony product of music that make Pavarotti mate a canis canis sheep mixture, I am spawned out of the apothecary.”
Stony product = rock
Pavarotti = He is(was) heavy (??)
= Heavy Rock
Tungsten – from Swedish language “tung sten” = “heavy stone/rock”
high density – 19.3 times that of water
Tungsten – also known as wolfram. Wolf and Ram – “canis canis sheep mixture”
tungsten is found naturally on Earth only in chemical compounds.
A “compound for chemicals” could be a chemists’ shop or an apothecary.
“I am spawned out of the apothecary.”
I might be clutching at straws with some of the above,but worth a go anyway.
My answer – Tungsten
The answer was Tungsten, or WolfRam in another word. The most common ore is Scheelite, discovered by the Swedish apothecar Scheele.
Sadly the riddle has allready gotten answered in a later post…
