A multicomponent heterogeneous system was modeled. As a carbon-containing component, the average composition of sapropel organic matter of the Mesozoic deposits of the West Siberian NGP (according to I.I. Nesterov) was introduced into the multisystem. Solid phases of the multisystem are represented by minerals of sandstones, clay rocks, and limestones.

Volcanic rocks of the Western Baikal region and Syria have similar geochemical characteristics of the sources due to the processes of delamination of the lithosphere, which entailed the isolation of the crustal and restitutic components of igneous melts. Delamination of the lithosphere of the Western Baikal region, which was developed during the transition from the South Baikal depression to the inversion part of the Tunka valley, is confirmed by seismic tomography data. Demination of the lithosphere of Syria is assumed by geochemical characteristics of volcanic rocks. By analogy with the Western Baikal region, which experienced the influence of the Indo-Asian convergence in the late Cenozoic, the development of the delamination of the lithosphere of Syria is associated with the deformation field of the convergent interaction of the Arabian plate and Eurasia, in which the structures of the Levantine basin and the dead sea fault system took shape

Terrestrial volcanism was widely distributed in the Tunka Valley of the Baikal Rift Zone. Underwater eruptions were characteristic only of the areas of connection of the eastern and western ends of the valley, respectively, with basins of lakes Baikal and Khubsugul. The Kultuk volcano erupted in underwater conditions in the early Miocene, about 18 Ma and the Hulugaisha and Gorkhonka ones – in the middle of the Miocene, about 15–14 Ma. Underwater volcanic eruptions, along with the accumulation of fine-grained sediments show existence in the early and middle Miocene of water reserviors that could belong to lakes Baikal and Khubsugul that were formed at that time.

From 5-year monitoring of groundwater in the Kultuk area, long-period (about 2.5 years) and short-period (months) variations in mercury concentration have been established. Long-period variations are associated with the preparation and implementation of the Baikal-Khubsugul seismic reactivation; short-period ones – directly with earthquakes. Mercury concentrations was low in groundwater in 2015, when seismogenic deformations developed in a state of crustal compression, and generally increased to 2020–2021, when seismogenic deformations occurred under extention. The course of the seismic process was reflected in a successive change in mercury/redox potential rеlationship in groundwater. It is proposed that the anomalous behavior of mercury during seismic activity resulted in increasing its concentration in the sedimentary layers of the second half of the 18th century through the present.

Systematized are the Munku-Sardyk high-mountain landforms originated due to exogenous processes of different genesis, age and location. Ancient: supraglacial preceeded Oka and sin-Oka very long development; subglacial progressive stage of Oka; subglacial regressive stage of the Okinsky glacier that developed in areas of relief development of the previous type; subglacial, developed on the periglacial relief of the first type, regressive, after thermal glaciations. Modern: nival-glacial, permafrost and erosion processes that are consistent (developing) with the vertical geocryological zonation of the regressive stage of glaciation: periglacial physical weathering and snowfields developing above modern glaciers and stone glaciers; glacial — within the development of modern glacial processes; solifluctionary; high-altitude-aufeis; mudflowers; permafrost-stone mountain streams and erosion activity of mountain rivers. Landforms resulting from all the above processes are complicated by denudation-accumulation slope processes.

Using of geological methods helps to solve archaeological problems. The chemical composition of Neolithic ceramics from the Tunka Valley (Republic of Buryatia) was studied using X-ray fluorescence spectrometry. Some compositional features of ceramic vessels in comparison with those of the same age manufactures from the Lena River valley have been revealed. A stable discrepancy in the chemical composition of the inner and outer walls of the vessels was found.

The results of an seismic variation experiment at the Babushkin test site and monitoring observations of the 234U/238Uactivity ratio in groundwater from a paleoseismogenic dislocation in a zone of the Main Sayan Fault are presented. Found is a similarity between effects obtained in the experiment and data at the monitoring station in 2014, but no similar effects during preparation and realization of the strong Bystraya earthquake in 2020. It is inferred that the monitoring observation of a single station is not enough for a successful prediction of a strong earthquake. It is necessary to support hydrogeochemical monitoring of several stations located on the test site in different structural conditions and provided different information on seismogenic deformations that change over time.
