Аннотация:This paper summarizis the results of previous and recent studies of minerals in Lower Mesozoic terrigenous rocks of the Koltogor-Urengoy trough and adjacent structures of the northern West Siberian Plate. The study reveals stages and paragenetic sequences of detrital and authigenic mineral formation with implications for the stages of the geodynamic evolution of the basin: syn-rift, transitional to syneclise, syneclise, and tectonic inversion. The microscopic observations of the textural and structural relationships between detrital and authigenic minerals were used to explain the mechanisms of mineral formation and sources of material, as well as the means of their interformational, intraformational, and basin-wide redistribution under the influence of different thermodynamic and hydrodynamic factors as a function of the geodynamic setting. The problems considered here may be applicable in hydrocarbon-reservoir studies.
