This study is concerned with the eolian deposits on the Baikal shore. It has been established that (1) the eolian sands are distinctly divided into two sequences: Khuzhir (Late Pleistocene) and Peschanka (Holocene); (2) the ilmenite enrichment of the sands is due to the removal of sand grains (containing mainly light minerals) by strong winds up the shore, first, from a dewatered beach zone, and then, from zones of psammitic-material transition. This leads to the concentration of ilmenite and other heavy minerals, first, within the beach zone, and then, within the zones of prevailing eolian-sand transition. The accumulation-transition zones are most enriched in heavy minerals, including ilmenite; (3) the ilmenite content in the study Ti-ore placer deposit shows a high correlation (R = 0.89) with the total content of heavy minerals.
Results of the activity of Quaternary glaciations in the western Baikal area are considered based on new factual material. Also, the problem of the formation of “watershed pebbles” in the area is discussed. Data indicating the fluvioglacial origin of the pebbles are reported. Special attention is given to the composition, lithology, and stratigraphy of glacial deposits and their geomorphologic position in the study area, which is one of the most hardly accessible and interesting regions in East Siberia in terms of both the geology of Quaternary deposits and archaeology. Results of spore-and-pollen analyses and archaeological evidence are reported.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
