Aleksandr Genkin
Formula:
(Pt,Pd,Rh)4Sb3
Colour:
Pale brown or yellowish tan
Hardness:
5½ - 6
Specific Gravity:
8.83 (Calculated)
Crystal System:

Name:
Named by Louis J. Cabri, John M. Stewart, J.H.T. Laflamme, and J.T. Szymanski in honor of Aleksandr Dmitrievich Genkin (28 July 1919 - 9 July 2010), Russian mineralogist at the Institute of Geology of Ore Deposits, Petrography, Mineralogy, and Geochemistry, Russian Academy of Sciences (IGEM RAS) in Moscow. He was a specialist in the ore mineralogy and geology of the platinum group minerals, in particular working on the Cu-Ni mineral deposits of the Noril'sk area of the Russian Federation. Later in life he was a pioneer of advanced techniques in the search for trace amounts of precious metals in sulphides and sulpharsenides. He helped to describe 20 minerals and was a founder of the journal Geologiya Rudnykh Mestorozhdenii (Geology of Ore Deposits).
The Pt analogue of ungavaite. Possibly the Pt-Sb analogue of 'UM1984-07-As:Pd'.
