Structure and condition of formation of Campanian deposits of the North-Western Caucasus (Galitsyno section)

Abstract

The description of rocks in the Galitsyno quarry located in the Adler region of the North Caucasus is given. The quarry is interesting because the excellent exposure in a relatively homogeneous stratum of carbonate rocks was able to identify certain changes that reflect the events common to the Late Cretaceous, in this case, Late Campanian, interval of events. These include carbonate sedimentation characteristic of this geochronological interval, constant fluctuations of the relative sea level, and periodic manifestations of volcanic activity. All these features confirmed both by the structural features of the section, the presence of various lithological types of rocks in it, and by the features of the composition of the complexes of microorganisms. The use of different methods of analysis of the factual material makes the obtained conclusions convincing.
