Sedimentation aspects of the Precambrian history of Phanerosoic
Abstract. In the paper the results of research and comparative analysis of events, stages and situations of the Precambrian sedimentogenesis as historic and genetic prerequisites for the estimation of common regularities of the hydrocarbons' behaviour during the four-milliard-year prehistory of Phanerosoic have been considered. The evolution model of geologic events in Precambrian based on the original data from the Baltic shield in comparison with other Precambrian regions has been given. It has been shown that the levels of hydrocarbon relative concentration in the exterior and interior Earth spheres and the potential of stratisphere oil and gas-bearing were undergoing a wave (pulsation) variation during Precambrian (as well as in Phanerosoic). Four exosphere-endogenous-exosphere turnovers of carbon dioxide correspond to four transgressive-regressive recourse megacycles composing Precambrian stratisphere. The hydrocarbons were accumulated in the sediment during the transgression, whereas carboniferous sediments were metamorphically transformed during the regression and hydrocarbons became highly mobile. The endogenous reservoir of the Earth carbon dioxide had been increasing.
