Аlternative local stratigraphical scales of the Upper Miocene of the Rostov Dome

Background . Definition of local stratigraphical units, the main which are formations, is important for geological mapping and correct understanding composition sedimentary complexes. This task yet to be solved some territories. Thus, Upper Miocene deposits extend widely across Rostov Dome in southwest Russia; however, definition formations there still its nascent phase. Aim Systematization ideas about units Dome, taking previous assumptions into account. Materials methods An analysis related was carried out. These were systematized with a focus on validity based current code. Results improved scale proposed. implies defining Taganrogskaya (Lower Sarmatian), Rostovskaya (Middle–Upper Donskaya (lower Maeotian), Merzhanovskaya (upper Aleksandrovskaya Pontian) formations. The correspondence alternative shown: Mokrochaltyrskaya Berdanosovskaya correspond Formation, while later proposed Formation corresponds Discussion. noted; priority highlighted. question creating an automatic system generalizing information discussed. Conclusion need parallel existence scales absent. However, subdividing relevant requires further discussion refinement.
