Abstract


The article presents the first results of the study of native platinum extracted from chondrite. The native platinum forms microinclusions in carbonaceous matter andchromites, which are found in ordinary chondrite. Native platinum forms micrograins and aggregates of cubic microcrystals, most of which are free from impurities. The composition of platinum-containing chromites corresponds to terrestrial analogues of ultrabasic mantle rocks. Assumption about the magmatic origin of platinum-containing carbon is made.

Keywords
