Circular structures of the Northern Black Sea Region a consequence of a planetary catastrophe

The paper formulates a new vision of the reasons for the formation of the modern structural-geological appearance of the Northern Black Sea and the offshore area of the Azov Sea. The catastrophic events in the Northern Black Sea, during the Permian-Triassic period, about 250 million years ago, allegedly occurred. Giant asteroid exploded (or just collapsed) when it entered the dense layers of the atmosphere, and its multifarious debris formed numerous circular structures on the Northern Black Sea during the fall. It has suggested that this space catastrophe is the forerunner of the famous Permian extinction of the terrestrial biota.  Graphically and descriptively, it has been proved that approximately along the Bataisk-Krasnoperekopsk-Izmail line, according to the RSD, 3 large circular structures and up to 20 small ones are decoded. It is proved – the line corresponds to the Northern suture zone, which separates the East-European platform from the Scythian epiorogenic zone. The suture area has been active for approximately 250 million years. It has been theoretically proved that it is the invasive effect of the cosmic body that is the root cause of the fault zone, which in Cimmeria evolved into the Northern suture zone. Using modern RSD made it possible to identify large circular structures of the Northern Black Sea Region. These are Azov, Bataisk and Kalamitska. Major research interest in the segments of the Azov astrobleme in the context of the oil and gas exploration work is determined. It is proved by retrospective geological information that the identifying structures have a significant depth of occurrence and here the earth’s crust should be saturated with a significant number of supply channels (decompression zones) favorable for hydrocarbon migration.
