Past Experience and the Present in the History of the Man and Nature Relationship in the Great Steppe

The considerable part of the Northern Asia is occupied with the steppe and forest-steppe landscapes stretched by a wide strip from Caspian Sea to mountains of Big Khingan.Archeologists claim, that from here on the Bering Bridge after a glacial age ancestors of American Indian tribes have left to the North America. In the Baikal Lake basin we find settlements of ancient Huns, subdued the Eastern and Western Europe in the beginning of last millennium.     

Investigation of forest-resources potential of Selenge River Basin on transboundary territory of the Republic of Buryatia and Mongolia

The author studied the issues of the present-day status of forest resources and forest management of the Selenge River Basin on the transboundary territory of the Buryat Republic and Mongolia. It is necessary to establish a good policy for wood cutting of the main and secondary use and reforestation.     

全球构造地貌中的大悬崖(英文)

高大并且广泛分布的构造悬崖是全球构造地貌的重要组成部分,是南方大陆和次大陆边缘的基本构造地形类型,同时也发育在亚洲东部的陆-洋过渡区。它们位于大陆边缘区的后缘,其地球动力学作用以大陆架、大陆斜坡和边缘海沉降区域的裂谷作用为特征。大悬崖的形成始于大陆岩石圈的变薄和裂解,持续发育过程较长,期间经历一系列的平行后退过程——即所谓构造夷平作用,导致大陆架沉积基准面的形成。大悬崖见于被动大陆边缘以及西太平洋陆-洋过渡带后缘。在陆内区域大悬崖不常见,而是在陆地升、降交界边缘区域出现其他的地貌构造特征。     

Geotechnogenesis problems

Geotechgjgensis is mineralogical geochemical transformation of minerals, rocks, and ores as consequence of impact on them in the process of performing geological-exploration and irrigation works, extracting and processing mineral resources, constructing transport, civil and military objects. These effects lead to discontinuity and moving different scale fragments ofuppor part of lithospere and conjugate hydro-and biosphere zones. Discontinuity predttermines the disturbance of matural systems dynamic equilibriu and acceleration of mftter transformation and migration processes. The final aim of studying geotechnogenesis minseralogy and geochemistry is the establishment of scientific foundations for developing ecological safety measures including also utilization fo geotechnogene deposits.     

Global Change and Regional Landscape Response and Desertification in Siberia

Climate changes and associated natural and anthropogenic processes have manifested themselves particularly clearly during the last two decades. The study of consequences of these changes has become one of the central scientific, social and political issues of our time (Pilot 2000; UNEP 2007).     

Technogenic hydrogeochemical anomalies of tungsten deposits in Kykylbey ore region

Peculiarities of the tungsten deposits drainage flow chemical composition formation, the development of which was ceased almost 40 years ago, have been considered. Migration peculiarities of ore components have been covered, and forms of their migration have been calculated. Inertial characteristics of the surface flow contamination are shown.     

Geodynamics and ore content of basite-ultrabasite complexes ofSiberian Platform southern framing rocks （Kodaro-Udokan and Muja zones of North Transbaikalye）

In southern framing of Siberian Platform, basite-ultrabasite intrusive complexes were forming over a long period of time (Early Proterozoic-Paleozoic Era) as a result of collisional and post-collisional processes. In Muja zone they formed mainly in island-arch geodynamic conditions, in Kodaro-Udokan zone-in continental. Most productive toward noble metals in Muja zones are basite-ultrabasites of the Dovyrensk complex‘, in Kodaro-Udokan basites of the Chiney complex. Gold in these formations has both mantle and crustal springs.
