... for the Oshurkovskoe fields. The carbonatite vein of the Torei field is also no older than Late Mesozoic, because it crosses the Middle-Late Jurassic trachybasalts of the Ichetui Formation. For the other fields we have only indirect geochronological data. Trachydolerites in the vicinity of the Gurvunur field, which...

... Ivan located west of it, which is part of the Lena River drainage area. This orography is the reason for the absence of extending tributaries of Arakhlei (the longest tributary, Gryaznukha River, is only 9.8 km) and specifies the formation of the water balance of the lake and its sedimentation...

... NE movement of deformed material (along the strike of the Okhotsk-Mongolian folded system). It was proposed that the arch formation began during the Late Riphean and continued in pulses during the Paleozoic and Early Mesozoic. The last two stages of the cover-folded arch formation with the emergence...

.... The process of thrusting was accompanied by the formation of olistostrome, then by the formation of isoclinal folds, structures of plastic current and melange, tectonization of olistostrome, protrusive injection of ultrabasite and calcareous tectonic erratic masses. It was conditioned by the southward...

... chemogenic carbonates and secondary aluminosilicates. The performed thermodynamic calculations confirm their possible formation in lakes. It is shown that the lake water is in equilibrium not only with carbonates, clays, and hydromica but also with zeolites, and the most alkaline and mineralized water...

...F.I. Enikeev Abstract Paleogeographic reconstructions for the Samarovo, Taz, Murukta, and Sartan glaciations reveal the formation conditions of proglacial lakes dammed by ice in intermontane depressions and valleys of large rivers in eastern Transbaikalia.
