(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 ...
-
(2004)Mapping in the East Gobi basin, supplemented by seismic data, reveals a structural and burial history for basins adjacent to the Zuunbayan and Tsagaan Els oil fields. The tectonic framework was combined with available well ...
-
(2002)The new Far East transregional ore belt of the meridional strike is considered. It was theoretically and practically justified in the last two decades. The structural base of the ore belt is an elongated (more than 3000 ...
-
(1986)The Pamir-Punjab syntaxis consists of two structural arcs with the crests facing northward—the Pamir and Hindu-Kush-Karakorum arcs. These arcs are mutually disharmonious, and the exterior (Pamir) arc is more tight, as ...
-
(1997)The tectonic structure of the Gulf of Avacha shelf is described on the basis of the interpretation of medium-scale geological and geophysical surveys. Large tectonic elements of the land and continental slop are correlated. ...
-
(1996)The geological structure of the Perekatnaya-Chernaya (Imbisha-Taukhe) interstream area is represented by a complex combination of synsedimentary tectonic inclusions (allochthonous sheets of different origins and age ranges) ...
-
(2002)This article reviews new data on the geological structure, geological-structural setting, and zonality of the Zgid deposit. Due to the discrepancy between the geological structure of the deposit atb the surface and at lower ...
-
(1990)Domelike volcanic uplifts are widespread on Venus. The author has compiled a map of such uplifts and coronae for the comparatively well studied northern part of Venus, as well as the less well known southern part of that ...
-
(2003)Tectonic stress is one of the fundamental data sets in Earth sciences comparable with topography, gravity, heat flow and others. The importance of stress observations for both academic research (e.g. geodynamics, plate ...
