Abstract
Study of losses sequences with interbeds of Paleosoils, Preglacial phenomena, cycles of sandy horizons and bioturbations, undoubtedly, gives us a great chance of reconstructing Quaternary climatology and its Paleogeographic changes. The most important principle is that the conditions, in which the strata had been formed, should be determined and their relation to different time scales of Quaternary (Climatologic, Lithologic, Bio- or Chronostratigraphic) should also be specified.
Dating of different loess horizons of a stratigraphic section is very useful in evaluation of Paleogeographic events, for variety of its principles and methods.
In summary, dating of loess sequences is based upon intervals of loess and soil horizons. Loess indicates climatologically dry and cold areas, but Paleosoils show warmer and more humid geographical conditions. Thus, in present sequences, loess and Paleosoil horizons are indications of glacial and inter- glacial periods.
This essay deals with problems in determination of Quaternary climatology, its Paleogeographic changes, and loess stratigraphy.
