Geothermal conditions of the Black Sea basin and its flanking

© Kutas R.I.

A scheme of thermal flow distribution in the Black Sea and adjacent areas of the land has been given, results of geological-geophysical analysis of thermal field including the model of formation during the process of evolution of sedimentary basin. Deep water depression of the Black Sea is specified by low heat flows (20-40 mVt/m2). The anomaly of low heat flows practically coincides with the contour of the Neogene-Quaternary depression, which indicates determinative role of its Post-Oligocene history in formation of modern morphology of thermal field. The anomaly of high heat flows (40-44 mVt/m2), specific for the structures of Late Mesozoic-Cenozoic stage of active development, is distinguished at the surface level of the upper mantle under the Black Sea mega-depression. The adjacent structures of the land are specified by preferably increased heat flows (50-80 mVt/m2). Several levels of thermal field are traced here, which conform with main stages of tectonic activization of this region.
