The material for this work was the data from 18 exploratory drilling wells laid by the Geological Exploration Trust of the Central Black Sea Region in the south-eastern part of the region and along its border with the North Caucasus Territory, which encountered known carboniferous rocks. The importance of studying Carboniferous stratigraphy within the Central Black Sea Region is determined by the geographical location of the region between the Donetsk and Moscow Region coal basins. Thus, the northernmost well in the area of our study, in Novy Oskol, is 240 km from the extreme southern outcrops of the Moscow Carboniferous, and 200 km from the extreme northern Donetsk (see article). Thus, the described Carboniferous deposits are a connecting link between these basins, which were filled with facies of completely different deposits - and which, from the hitherto dominant point of view, represented the results of fundamentally different geological processes.
