Experimental Study of Platinum Interaction with Carbonaceous Matter and Sulfiir at 200-400℃ and 1 kbar

摘要

The potential of platinum mineralization in carbonaceous rocks (black shales) attracted the attention of geologists after the discovery of a high concentration of PGEs in ores of gold and copper deposits [1-3]. The PGEs in these rocks are characterized by diversity: native metals, intermetallics, sulfides, arsenides, and presumably metal-organic compounds [2, 4]. The existence of platinum-hydrocarbon complexes was supported by experimental studies [5] and later by finds in sublimates of Kudryavyi Volcano [6].
