Key
Locality type:


Au-Cu-Pd mineralization in "lavas" (tholeiitic basalts and dolerites). Cu-Au-Pd and Pd-Cu-(Te+Sb+S+As) systems phases are present. The source of both the rocks and PGMs is probably a hotspot. The same hotspot may be responsible for PGM mineralization in eastern Greenland. Sampled locations near 80.784660N, 47.604706E

In addition to the listed species, various S-Te-Sb-Pd-Cu phases are reported.
