(2004)We model evolution of a continent-continent collision and draw some parallels with the tectonic evolution of the Himalaya. We use a large-scale viscoplasto-elastic thermomechanical model that has a free upper surface, ...
-
(2003)The Verkhoyansk–Kolyma belt (VK) forms the western part of the Verkhoyansk–Chukotka Mesozoic orogen (NE Asia) and lies between the Siberian craton on the western side, the Mesozoic–Cenozoic Koryak–Kamchatka accretionary ...
-
(2012)In this paper we present the results of a generalization of paleomagnetic data for the territory of the Siberian craton and its folded framing that were obtained during the last fifteen years. We propose a new version of ...
-
(2001)We report generalized paleomagnetic data on the Vendian-Cambrian island-arc complexes of the southwestern framing of the Siberian Platform. They allow restoration of the arrangement of fragments of paleoisland arcs in the ...
-
(2002)The distribution of the heat producing elements within the lithosphere provides an important control on continental thermal regimes and the mechanical strength of the lithosphere. Moreover, the strong temperature dependence ...
-
(2001)Structural studies of BDP-98 core recovered during deep drilling on the Akademichesky Ridge (Baikal Drilling Project) have shown that the Baikal bottom sediments are cut by tension and shear joints of various scales, locally ...
-
(2001)The geology of Lake Sevan is characterized by the structure of a pull-apart basin. Methane emission from the lake surface correlates with evidence of physical and chemical water properties, remote sensing, etc., and suggests ...
-
(2004)Metamorphic pressure (P)–temperature (T) paths are commonly used as tools to interpret the tectonic history of orogenic belts, those deformed belts of rocks that record past activity along active plate margins. Many studies ...
-
(1986)Whether the tectonosphere is active or passive depends on the thermal regime of the Earth's interior and the depth of the lithosphere-astenosphere boundary. Lithospheric thickness increases as it cools and decreases as it ...
-
(1988)There is reason to think that the origin of the seismoactive (focal) layer is determined by deformation of an earthquake-generating layer of large volume. The earthquake-generating layer includes not only the part of the ...
-
TECTONIC NATURE AND SEISMIC RESPONSE OF TOP-BASEMENT DETACHMENT FAULTS IN MAGMA-POOR RIFTED MARGINS (2003)Top-basement detachment faults (TBDF) represent exhumed segments of downward-concave detachments accommodating tens of kilometers of offset. TBDFs are key structures of magma-poor rifted margins, but are difficult to ...
-
(1999)The locations of great earthquakes that occurred in 1994 at the eastern margin of the Eurasian continent were examined in relation to the geology and geophysics of the region. These data are used to derive a seismotectonic ...
-
(2002)The NW-Caucasus fold-and thrust belt essentially corresponds to the inverted western Flysch Zone of the Great Caucasus Mountains, a deep basin that developed from Late Jurassic to Eocene times between the Scythian Plate ...
-
(2002)Early to Middle Triassic rift-related basaltic magmatism occurred along the entire length of the northern circum-Pacific margin and was followed by Triassic to Early Jurassic (230-190 Ma) development of marine island arcs ...
-
(1998)More than 420 million oz of gold were concentrated in circum-Pacific synorogenic quartz lodes mainly during two periods of continental growth, one along the Gondwanan margin in the Palaeozoic and the other in the northern ...
-
(2001)Samples from plutonic belts and individual intrusions in the Sakha Republic (Yakutia), northeastern Russia, were analyzed using 40Ar/39Ar geochronology and trace element geochemistry. Four phases of activity were identified: ...
-
(2003)A tentative tectonic subdivision for the Chukchi and East Siberian seas has been created based on the processing and analysis of new satellite altimetry and magnetic data and published materials that include information ...
-
(2001)Characteristics are given of pre-Cenozoic and Cenozoic structural-material complexes of southeastern Kamchatka, and paleogeodynamic conditions of their formation are considered. A tectonic sketch map has been compiled of ...
