The structure of the Romanian Western Black Sea shelf has been studied before 1970 and described in publications that serve today as an important point of reference in the structural geology and geotectonic studies. After the year 2005, a new set of gravimetric data has been acquired by the Romanian National Institute of Marine Geology and Geoecology, that has been obtained by compiling over 13.400 km of profile measurements on the Romanian and Bulgarian offshore. By combining this newer data with an analysis on the structural geology and seismic interpretation, more complex and detailed studies have been made possible, providing us with a better regional understanding of the structural dynamics that took place since the last large-scale hypothesis has been issued, giving us a newer systematic approach to creating newer local structural models and understanding the geomorphology of the continental shelf deep geological structure. For the purpose of this study, two calibration profiles have been chosen, starting from the continental part of the Moesian Platform that continue towards the deep-sea region. The profiles have been verified and compiled by using the geological and structural reference and have been interpreted with the help of the newest gravimetric data so a better geometrical representation of the crustal architecture can be highlighted. The results show different areas where the crustal layer has been affected by the Western Black Sea back-ark opening of the basin, during the early Cretaceous times.
