Keithconnite
Keithconnite is an IMA-recognized mineral species in the sulfide class, with the chemical formula Pd₂₀Te₇.
It crystallizes in the hexagonal crystal system (space group R-3).
Key properties: specific gravity 11.72.
IMA symbol Kei, IMA status: approved, named in 1978.
Rare with other platinum-group minerals in layered ultrabasic complexes and their placers.
It is found associated with Merenskyite, kotulskite, telluropalladinite, moncheite, vysotskite, gold, magnetite (Stillwater complex, Montana, USA).
The mineral was named to honor H. Keith Conn (1923–), the geologist largely responsible for the discovery of Pt–Pd mineralization of parts of the Stillwater complex, Montana.
