Petrologic and geochemic features of the ore-containing substratum in hydrothermal gold deposits. P. 1. Petrology of the near-ore metasomatism

The relevance of the research is caused by the necessity to correct and elaborate on geological (metallogenical) component of the hydrothermal gold deposits formation theory within the framework of which the conflicting ideas about ore-formation geological making (energy and metalliferous fluids sources) go in four competing hypotheses eliminating one other. Therefore it is impossible to develop a complex of effective forecast-search mineralization criteria. The main aim of the study is to prove the belonging epigenetic mineral associations at the ore-formation stage in near-ore alterating black shales series to metasomatic formations, contrary to the wide-spread ideas, and, as consequence, material-genetic similarity of apoblackshales zoning metasomatic columns (haloes) with those, formedin non-shale (crystalline) substratum; external (non-rock) sources of gold and other metals, concentrated in deposits formed in black shales series.
