The multi-layered key section of Tologoi is situated on the Selenga River left bank, 15 km southwest of Ulan-Ude city (51o45′ N, 107o29’ E), in the Western Transbaikal region. It holds a long record of Quaternary sedimentation since early Late Pliocene through Holocene, with the only minor gap in the beginning of Early Pleistocene. Comprehensive studies have been carried out on the lithology, geochemistry, fauna succession and paleoenvironment reconstructions. This paper summarizes the data acquired on the geology and stratigraphy of the Tologoi section. The authors investigated the composition, structure and formation conditions of the section, as well as the intensity of weathering, rock geochemistry, grain size and biostratigraphy. |
