Lithological-magneto-palynological characteristics of the Upper Miocene, Pliocene and Gelasian deposits of the Cenozoic reference section of the Dnieper-Donetsk depression (Ukraine)


 Well 11 is located near the village of Velika Lanna, Krasnograd District, Kharkiv Region, and at current stage research most representative section continental Upper Cenozoic deposits Dnieper-Donets depression. For first time, a comprehensive description Miocene, Pliocene, Pleistocene obtained from results paleopedological, palynological, paleomagnetic studies presented for region. Characteristic features 13 climatolites (pedocomplexes intersoil clays) including five upper three lower two Pliocene correlated with Gelasian International Stratigraphic Scale were determined. According to miner- alogical studies, mineralogical strata such as montmorillonite-kaolinite, hydromica-montmorillonite, hydromica traced section. The boundaries are confined levels Salgir–Liubimivka Siversk–Beregove climatoliths. spore-pollen complexes all studied described. It was established that characterizing each climatolith differ in taxonomic composition, ratio pollen main groups plants, presence characteristic taxa. Changes composition spectra soils pedocomplexes well clays embryonic formed during short-term warming time cool stages periods traced. described compared those same age adjacent regions, which allowed identifying general regional complexes. A detailed record changes geomagnetic field formation Miocene-Pleistocene obtained, enables construct reflecting areas normal, reverse anomalous polarity. nature distribution areas, tied Cox scale. All these materials carrying out stratigraphic dissection Miocene-Gelasian section, substantiate feasibility defining it reference depression.
