Thermobaric Depth Settings of Sedimentary Rock Basins and Their Fluid Dynamics: Communication 1. Zonation of the Stratispheric Structure and Constraints of Anomalous High and Superhigh Fluid Pressures

Abstract

The paper addresses zonation of the stratisphere: thermobaric conditions in its deep zones with anomalous high (AHP) and superhigh (SHP) fluid pressures, as well as main types of fluid-dynamic setting in the upper zone. Mechanisms of the clay dehydration and processes of oil-and-gas formation governing the development of superhigh fluid pressures in the lower zone of rock formation are also discussed.
