About Rutheniridosmine
Formula:
(Ir,Os,Ru)
Colour:
Silver-white
Lustre:
Metallic
Hardness:
6 - 7
Crystal System:
Hexagonal
Name:
The name reflects its composition , being comprised of RUTHENium, IRIDium, and OSMIum.
Rutheniridosmine was defined as a new species by the IMA-CNMMN-approved nomenclature of the natural alloys of Os-Ir-Ru (Harris & Cabri 1973). The natural occurrence of the mineral was confirmed in the same paper by Harris & Cabri (1973) from many Canadian localities, from Japan and from an unknown locality in New Guinea. The compositional field for rutheniridosmine was restricted by the revised nomenclature (Harris & Cabri 1991) to alloys in which Ir is the dominant element.
