Thermobaric Depth Settings of Sedimentary Rock Basins and Their Fluid Dynamics: Communication 3. Superhigh Pressures in the Stratisphere and Salt Diapirs

Abstract

The paper addresses regularities in the location and conditions of the formation of salt diapirs. Their formation is attributed to a thick salt “cover” characterized by the generation of superhigh pressures owing to phase transformations in closed physicochemical systems. Such transformations are responsible for the flow of salts and their injection along tectonic fractures and faults toward the Earth surface. Similarity of the formation scenario of salt diapirs and mud volcanoes is emphasized. Influence of superhigh pressures on the autonomous orogeny of the sedimentary cover is inferred.
