Abstract:

This study investigates the origin of the Black Sea, focusing on the East and West Black Sea basins. Data such as Curie Point Depth values, heat flow, bathymetry, Moho depth, sediment thickness, and magnetic depth estimation were analyzed to explore the region’s geological features. Correlations between these parameters were assessed for each basin, shedding light on their tectonic history and the influence of volcanic rocks. Thinner sedimentary covers enhanced the detectability of rocks with higher magnetic properties, while the interiors showed lower magnetic anomalies due to younger sedimentary rocks. Edge detection techniques, like tilt angle and Local Wavenumber methods, improved magnetic data interpretation. The study computed Curie Point Depth and heat flow using 65 blocks, revealing greater depths in the Western Black Sea (up to 32 km) compared to the Eastern Black Sea (24-28 km). Two profiles (A-A’ and B-B’) were examined for further insights. Overall, this study provides valuable insights into the geological evolution of the Black Sea basins.
