Heat field of the south-eastern part of the Dnieper basin of Dnieper-Donets depression

Abstract

The values of the deep heat flow were studied in 182 boreholes. They are grouped into 104 points. The resulting densification of the network eliminates some of the "white spots" in the study of the heat flow of the south-eastern part of the DDD. A chain of positive anomalies of the heat flow exceeding 50 mW/m² is assigned to the south-western boundary DDD fault. Near the center of the region, the highest heat flows exceed 70 mW/m². The negative heat flow anomalies are common in the region considerably wider. Some of them tend to the activated fault zones. The analysis of data and related information allows us to consider the increased heat flows as a consequence of the modern activation.
