Talla says: March 16, 2012 at 21:54 : it’s a potassium feldspar matasomite known as Charoite with Canasite found only on the Murun Massif, Sakha Republic, Russia (volcanic event – Siberian Traps).


Norilsk deposit, a part of the Siberian traps.
Quote Wikipedia: “Charoite (K(Ca;Na)2Si4O10(OH;F)·H2O), pronounced CHAR-oh-ite, is a rare mineral, first described in 1978 and named for the Chara River. It has been reported only from the Sakha Republic, Yakutia, Siberia, Russia.[3] It is found where a syenite, the Murunskii Massif, has intruded into and altered limestone deposits producing a potassium feldspar metasomatite. Charoite is translucent lavender to purple in color with a pearly lustre. However, it is a discrete mineral rather than a rock. Charoite is strictly massive in nature, and fractures are conchoidal. It has an unusual swirling, fibrous appearance, sometimes chatoyant, and that, along with its intense color, can lead many to believe at first that it is synthetic or enhanced artificially.”

Quote: “The Murun massif is located on the Aldan Shield. In the atlas you can find it between the Charaa and Tokko river, south of Olekminsk. The Murun massif is of course famous for charoite. The Murun massif is (type) locality for a number of unusual minerals. This is caused by the very complex geology of the Murun massif.  Vastly simplyfied the Murun massif is a differatiated alkaline intrusion. ” Murun Massif
