SILVER SPHEROIDS IN GRAPHITE-BEARING ROCKS OF THE MAKSYUTOV COMPLEX, SOUTHERN URALS

Abstract

Findings of graphite pseudomorphs after diamond and metamorphic nanodiamonds have been reported in the recent literature. Therefore, we attempted to extract and scrutinize graphite pseudomorphs and diamond particles from graphite-bearing rocks of the Maksyutov Complex. We used the thermochemical dissolution method applied for the extraction of microdiamonds. The byproduct of the insoluble residue in the experiments contained unusual spherical particles mainly represented by very interesting spheroids of native silver.
