3D chronostratigraphic model of the Paleogene in the onshore part 
of the Dolna Kamchia Basin (Eastern Bulgaria)

This study is based on biostratigraphic data from 53 boreholes and chronostratigraphic interpretation of 16 seismic profiles from the onshore part of the Dolna Kamchia Basin (DKB). Seven Paleogene chronostratigraphic units were recognized (the Danian, Thanetian, Ypresian, Lutetian, Bartonian, Priabonian stages, and the Oligocene Series). For visualization of their spatial distribution and relationships, a 3D chronostratigraphic model is created.
