Fluid Nature of Carbonification and Bulk Argillization on the Gusevskoe Deposit of Porcelain Stones (Southern Primor'e)

摘要

Significant interest in natural carbonaceous systems is determined by their metallogenic role as concentrators of rare metal and Au-PGE mineralization [3, 6, 8]. Carbonaceous matter, which underwent the stage of thermolysis or was formed as a result of fluid carbonification of rocks, contains microphases of ore elements of different valent states including native ones, as well as mineral parageneses "forbidden" for common hydrothermal systems [2, 4, 6]. It is important to study the mechanism of replacement of silicate matter by carbon and the related character of textural and chemical transformations.
