Glacial deposits and “watershed pebbles” in the Western Baikal area

Abstract

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.

Pyrolysis of Technogenic-Redeposited Coal-Bearing Rocks of Spoil Heaps

“…Mineral particles 0.25-0.05 mm in size were separated using bromoform into light and heavy fractions. The weighted fractions were subjected to immersion analysis using a polarization microscope according to the traditional method [15]. The mineral content was calculated from 500 randomly selected grains taken as 100%.…”

Deposits from the Glacial Age at Lake Baikal

“…2) and block-boulder-sand (Fig. 3) deposits with debris and gruss, which form a thick uniform rock unit called by us "Del'bichinda" Akulov et al, 2008). Gray silty inequigranular sand is the main filling material occurring in the form of a polymict glacier milk.…”
