The intense construction of the objects of the Sochi 2014 Olympics in the valley of the Mzymta River is proceeded within very complex geological structure of the region and the development of modern exogenous processes (modern or ancient landslides). The main difficulties in the division and correlation of geological sections is the similar lithological composition of units of Cretaceous and Quaternary ages (mainly terrigenous, clay-dominated) and the inability to establish and trace the geological boundaries in natural and artificial outcrops and the core. In this regard, the application of the method of the sequence analysis of the cyclic sequences is very actual. This study was supported by 5 geological routes and 386 points of observation, description of the cores from 86 wells and 10 test pits, petrographic study of rocks in thin sections, micro- and macropaleontological analysis, geochemical analysis of elements and oxides using a MARC.GV X-ray-fluorescent spectroscope and Rock Eval 6 pyrolysis analysis. By this complex method of study the problem of stratigraphic division and correlation within arera of construction was solved. A polygenetic model for Aptian and Quaternary rocks was proposed. This work was supported by the Russian Foundation for Basic Research, project no.12-05-00263.
