Tectonics and stratigraphy| Summary: | The information on lithofacial composition, stratigraphic position of gold-bearing sedimentary and pyroclastic formations of Volyn-Podіlsky plate and typomorphic features of native gold contained in them is presented. It is established that the gold content of sedimentary formation units is represented in a wide age range - from the reef to modern alluvial deposits of surface watercourses. It was found that regional specifics of gold bearing in sedimentary and pyroclastic formations of the Volyn-Podilsky plate is the presence of copper-, mercury-containing gold, electrum, two- (Au, Cu) and three-component (Au, Cu, Ag) solid solutions, golden copper, spherical grains, as well as gold (lamellar, spherical, lumpy) porous-segregation, myrmecite-like structure. Peculiarities of gold morphology and chemical composition and geological position of the region allow to predict within the territory of Volyn-Podilsky plate different age (from reef to Quaternary) and different genetic (placer, dia-, catagenetic, hydrothermal) ore occurrences of gold in different genetic sedimentary (continental and continental). ) and pyroclastic formations. |
