Quaternary stratigraphy and developmental history of the Central Russian Periglacial–Loessal Province

Resumo

As a result of complex investigation in the Central Russian Loessal Province, detailed lithologic, geochemical, paleopedological, and paleontological characteristics of the young deposits of the stratotype section Mikhailovka are obtained. They provide the basis for facies genetic differentiation, stratification, and correlation of particular horizons chronologically coordinated by paleopedological and paleontological data with the geological scale of the Neopleistocene. The loess–soil sequences corresponding to climatolites of the Lower, Middle, and Upper Neopleistocene are established and characterized. In dynamical history of the Central Russian Periglacial Loessal Province, thirteen paleogeographical stages of natural–climatic changes (seven warm interglacial and interstadial epochs, six cold epochs alternating with them) are revealed. A rhythmic climatic substantiation for the stratigraphical division of recent sediments in the investigated region is provided.
