| contents | The purpose of this work is to prove the genetic diversity, i.e., heterogeneity of the Duvanny Yar edoma sequence, as well as its nonsimultaneous formation, i.e., the heterochronous nature of its different parts along both vertical and lateral directions, based on the study of the cryogenic structure of the whole massif and the correlation of previously obtained radiocarbon ages with the AMS and other new data on the ages of organic microinclusions, alkaline extracts, and spore-pollen concentrate, which have been extracted directly from the Late Pleistocene syngenetic recurrent ice wedge complex. The results obtained have made it possible to propose a fundamentally new version of the structure, age, and formation conditions of the studied Late Pleistocene polygonal ice-wedge complex. |
