The article presents data on the structure of transition zones from areas of relative downwarping (intramountain depressions) to anticlinor uplifts dividing them. The geological and geophysical data obtained by the authors in recent years in different areas of the Northern Tien Shan are considering and discussing to compare the structure and tecton...
Structural-morphological ensembles of different ranks for Pamir — Tien Shan segment of Central Asia and their possible correlation with the data of remote geophysical investigations are considered in the paper. Results of such correlation analysis are discussed. A bright example of the morphostructures of cross-regional scale on the territory of th...
The basement surface and sediments of the Kochkor basin have been studied by structural geological and geophysical methods. The work included high-resolution mapping of the southern basin margin, with a focus on Cenozoic basin stratigraphy, structural unconformities, basement/sediment contacts, and latest deformation (folds, fractures, and faults)....
Based on a complex study of the upper crust structure in the southern margin of Kochkor basin (Northern Tien Shan), including study of the structure of the Cenozoic sedimentary cover, the deep geoelectrical structure, the structural unconformities, and occurrences of recent deformations in the basement rocks, new geological–geophysical cross sectio...
18.11.2016 г. Проведены детальные структурно-геологические исследования на северном склоне Киргизского хребта. Изучены деформации пенепленизированной поверхности палеозойского фундамента, структуры дезинтеграции гранитов и морфоструктурная выраженность позднекайнозойских текто-нических движений. На основании данных о положении останцов предпалеоцен...
A structural–geological study has been performed on the northern slope of the Kyrgyz Ala-Too Range. Deformations of the peneplaned Paleozoic basement surface, structures of granite disintegration, and morphostructural manifestation of Late Cenozoic tectonic movements have been investigated. Based on the location of pre-Paleocene peneplain remnants...
После вхождения в состав консолидированной коры гранитные тела не остаются ее пас-
сивными составляющими, а выдвигаются в верхние горизонты, образуя разобщенные кря-
жи или группы возвышенностей, часто в окружении более устойчивых к выветриванию ком-
плексов. Геологические и геоморфологические наблюдения свидетельствуют, что подъем про-
исходил имп...
Presented data show that granites after they become a part of consolidated crust do not remain passive units and move upwards, finally forming separate ridges or mountain groups, often surrounded by more resistant to weathering rock assemblages. Geological and geomorphological evidences suggest impulsive nature of the massifs uplift that continued...
We studied the infrastructure of granite massifs of the Central Tien Shan and its correlation with the electric conductive layer of the upper crust, which made possible to reveal new peculiarities of the structure of the granite layer in the region and to clarify the nature of low resistivity layers.
The Ysyk-Köl Basin filled with Lower Jurassic–Quaternary sedimentary rocks is the largest intermontane negative structural unit of the northern Tien Shan. The basement of this basin is composed of Precambrian–Paleozoic rocks, largely of Ordovician and Silurian granitoids exposed in mountain ranges of the basin framework and as separate anticlinal d...
Значительные объемы (до 50% и более) верхней коры континентов представлены гранитами, и грани-
ты, безусловно, должны влиять на формирование структуры земной коры и особенности ее эволюции.
Обычно полагают, что граниты после остывания и вхождения в состав фундамента представляют со-
бой достаточно пассивные объемы, не подверженные серьезным структу...
The paper describes tectonic assemblies determining structure and kinematics of the plate evolu�
tion in the eastern segment of the Gobi Altay and Gobi Tien Shan intraplate reactivation zones in southern
Mongolia. These zones are characterized by deformations corresponding to a 3D brittle–ductile shear flow.
The structural and compositional reworki...
Clastogenic rocks spatially associated with granite massifs have been reported in the geological literature from different regions: Caucasus (Leonov, 1974, 1991), Urals (Puchkov, 1968), Kazakhstan (Svarichevskaya and Skublova, 1973), Transbaikal region (Leonov, 2008; Lobanov et al., 1991), Tien Shan (Leonov et al., 2008), North America (Beroush, 19...
Disintegrated granitoids, which frequently enclose abundant clastic material of the same rocks, are widespread in the upper parts of the Earth’s crust. They occur both on the surface and under the thick sedimentary cover. Two processes are responsible for the formation of such rocks: supergenic (chemical and physical weathering) and tectonic (proto...
The structural setting and geochemistry of the Devonian dikes in the Kola Peninsula are considered. The alkaline dikes are controlled by rift- and drift-related structural elements. The first type of structures is exemplified by the Khibiny-Kontozero Fault Zone, which is regarded as a propagation zone of the East Barents Rift. The second type compr...
Complex geological and geophysical data obtained during recent research by the Marine Arctic Geological Survey Expedition
OJSC (MAGSE) indicate that the Riphean Chapoma graben located on the southeastern shore of the Kola Peninsula has its extension
under the Gorlo Strait of the White Sea water area and joins the Leshukonsk riftogenous graben as an...
Specific rocks (tectonomixtites) developed in the framing of Mongolian granite massifs (Dzuramtai and some others) at the
Mesozoic section bottom are studied. It is shown that the tectonomixtites are tectonic rocks rather than eluvial or sedimentary
rocks, as was considered previously. They formed in the Cenozoic in the process of granite protrusio...
The tectonic evolution of the Por’ya Guba segment of the White Sea Rift System began in the late Paleoproterozoic, i.e., soon
after completion of the Svecofennian collision. The fracture system that controlled localization of the lamproite dike complex
was formed under conditions of horizontal compression combined with shear. Subsequently, this sys...
The southeastern coast of the White Sea and Kii Island incorporates outcrops of conglomerate-type rocks similar to boulder dikes filling tensile fractures in the early Precambrian basement of the platform. They are related to the southwestern flank of the Onega Graben representing the southeastern segment of the Onega–Kandalaksha paleorift. Genesis...
The REE geochemistry of alkaline rocks in the Kandalaksha (9 samples), Kachinnyi (25 samples), and Kuzokots (22 samples) dike swarms of the Belomorian dike belt has been studied. Dikes from the Kachinnyi and Kuzokots swarms are related to the respective outer and inner parts of a concentrically zoned system. The Kandalaksha swarm belongs to another...
A lineament map of the system of greenstone belts of the Northern part of the Baltic Shield is used to analyse the correlation between 36 measurements plus 34 additional derived geometric parameters of the lineament network and phenomena relating to gold mineralization. The results of the analysis show a specific structural control for certain type...
