..., and Salair Ridge, the compositions of PGM and microinclusions in them, and the dominant mineral assemblages testify to several possible primary sources of PGE mineralization: (1) UralianAlaskan-type intrusions; (2) ophiolite associations, including those formed in a subduction zone; (3) ultramafic alkaline...

...”. The appearance of these thiospinel- and konderite-type chalcogenides, which are uncharacteristic of layered intrusions, is related to the anomalously S-poor character of the Kirakkajuppura PGE deposit, which is similar in this respect to the UralianAlaskantype complexes.

... Columbia are associated with volcanic belts in which principal rock types are alkaline augite and hornblende porphyries ranging from ankaramite to augite alkali basalt and hornblende trachybasalt.

... intrusions of UralianAlaskan type. Ninety percent of the PGM grains studied consist of Pt–Fe alloy, typically with a rhodium content in the 1–2 wt.% range. Pt-bearing Os–Ir–Ru alloy occurs in three variants: (1) heterogeneous grains with an exsolution texture, (2) intergrowths of Os–Ir alloy with Pt–Fe...

... are present (because of the presence of minor PGE). For instance, the iridium trend is most characteristic of platinum deposits of UralianAlaskan and Aldanian types, related to zonal mafic-ultramafic intrusive bodies in both orogenic (Urals, Colombia and others) and platform (Inagli, Kondyor and others...
