Mineralogy and geochemistry of rocks in interformational contact on Sauripe ridge

New data on petrographic, geochemical and mineralogical features of basic lithological rock types, composing basal horizons of uralides, have been presented. Conclusions about genetic and stratigraphic affiliation of deposits, sources and supply of terrigenous material were made. The stages of epigenetic transformations and their contribution to modern rock patterns were traced. The lithochemical features of gold mineralization were determined. The comparison and typification of interrelations of the basement and sedimentary cover was made. The type sections were described that were related to each possible variant of basement/cover interrelations. The lithochemical features of gold mineralization were determined that were necessary for the forecast of rare- and noble metal mineralization in Northern Ural Lower Paleozoic strata.
