This project included both direct work with core material, conducting a series of laboratory studies on it in order to determine the conditions of sedimentation, understanding their extent, determining the age of rocks, their qualitative and quantitative characteristics, and facies modeling to obtain facies maps, correlation schemes and profiles. One of the most interesting and important stages of the project implementation was biostratigraphic analysis and the construction of a correlation scheme on its basis in order to conduct a qualitative correlation of the section, which is the basis for identifying the conditions of sedimentation and understanding their strike in space.</em></p>TriassicUpper Permianostracodscorrelationтриасверхняя пермьостракодыкорреляция
