Telargpalite
Telargpalite is an IMA-recognized mineral species in the sulfide class, with the chemical formula (Pd,Ag)₃Te.
It crystallizes in the cubic crystal system.
Key properties: specific gravity 7.378.
IMA symbol Tlp, IMA status: approved, named in 1972.
Found in metasomatically altered Cu–Ni sulfide ores (Talnakh area, Russia); in the layered ultramafic Stillwater complex (Nye, Montana, USA).
It is found associated with Chalcopyrite, bornite, millerite, braggite, silver, kotulskite, clausthalite (Talnakh area, Russia).
The name refers to the constituent chemical elements, TELlurium, ARGentum silver, and PALladium.
