Cabriite

Cabriit is a very rare mineral from the mineral class of elements, specifically the metals and intermetallic compounds. It crystallizes in the orthorhombic crystal system with the chemical composition Pd2SnCu and constitutes up to 4 mm of pink color in Mooihoekit grains.

Etymology and history

Cabriit was the first time in 1970 by T. L. Evstigneeva and A.D. Genkin found in the type locality on the Taimyr peninsula in northern Siberia (Russia). It was named after the Canadian mineralogist Louis J. Cabri.

Classification

In the classification by Strunz Cabriit is counted among the metals and intermetallic compounds, a subset of the elements. After the 8th edition forms a group together with Naldrettit, Paolovit, Taimyrit and Tatyanait. In the 9th edition it forms with Paolovit a subgroup of the PGE ( platinum group elements ) metal alloys.

In the classification by Dana, it forms a separate subgroup of the metallic elements and alloys with platinum metals.

Education and Locations

Cabriit forms in Mooihoekit ores and galena - chalcopyrite veins. It is associated with Mooihoekit, Sperrylit, Geeversit, Putoranit, Paolovit, Talnakhit, Sobolevskit, polarity, Froodit, Auricuprid, silver, cassiterite, stannite, chalcopyrite, Valeriit, galena, sphalerite and magnetite.

In addition to the type locality further finds from the Sayan Mountains in Tuva are (Russia) and Lac- Mégantic known in the Canadian province of Québec.

Crystal structure

Cabriit crystallizes in the orthorhombic crystal system, space group Pmmm with the lattice parameters a = 7.88 Å, b = 7.88 Å and c = 3.94 Å and four formula units per unit cell.
