(2000)Data for the Altai-Sayan region were used to compare land relief, neotectonic structure, the morphology and kinematics of active faults, and seismotectonic crustal deformation to the topography of the top of a low-velocity ...
-
(1997)The velocity structure of the crust and uppermost mantle beneath the DSS profile Quartz in northwestern Russia is determined using a linearized seismic tomography scheme. The analysis is performed on the northern 2200 km ...
-
(2003)The Sutai Range is a structural and topographic culmination at the southeastern end of the Mongolian Altai and a world-class example of an actively forming restraining bend. The range occurs at a major stepover zone along ...
-
(2004)Felsic magmatism has occurred over a large region of East Asia since Jurassic times and has provided important mineral resources such as tin, tungsten, base metals and gold. The circum-Japan Sea region preserves various ...
-
(1980)The paper discusses the results of geodetic investigations performed in the region of the large 1975-1976 Tolbachik fissure eruption in Kamchatka. Using data from repeated triangu-lation and trigonometric levelings, ...
-
(2003)We propose that the internally zoned, Li-bearing Tin Mountain pegmatite in the Harney Peak granite-pegmatite system of the Black Hills, South Dakota, crystallized from fluid-rich, compositionally complex melts at 400-350C. ...
-
(2004)The existing 2D and 3D depth imaging approaches using multichannel teleseismic receiver functions (RFs) can result in significant artifacts caused by misinterpretation of signal-generated noise resulting from broadside ...
-
(2001)Unravelling the underlying causes of mountain building is one pivotal issue of geotectonics. The most popular model invokes crustal thickening through horizontal, across mountain ranges, contraction of the area occupied ...
-
(1988)In recent years much attention has been paid to the study of crustal movements within tectonically active regions. The present work is specially of interest since it deals with the site where one of the largest hydroelectric ...
-
(2002)The Alfred Wegener Institute of Polar and Marine Research, the University of Bergen and Hokkaido University acquired new seismic refraction data along a transect from the Knipovich Ridge to the inner Van Mijenfjorden in ...
-
(2002)An investigation of the teleseismic P-wave coda is performed using the single-scattering approximation. The method allows one to image short-wavelength scale (<=2 km) velocity and density heterogeneities and structures ...
-
(1999)An analysis of deep crustal structure and seismicity was performed along four traverses (Bazalt, Rubin, Kvarts, and Armash-Akhaltsikhe), which cut across seismic areas, to detect differences in crustal structure between ...
-
(1985)Based on deep seismic sounding data, a velocity model of the Earth's crust has been developed for the Kamchatkan segment of the Pacific transition zone. The velocity difference in the structure of the continental and oceanic ...
-
(1989)Despite the large amount of deep seismic sounding [DSS] work done in the Northwest Basin, the traverses were set out very unevenly, and mostly cross the central and southwestern parts of the basin, west of the Shatskiy ...
-
(2002)The Cenozoic rift system of Baikal, located in the interior of the largest continental mass on Earth, is thought to represent a potential analog of the early stage of breakup of supercontinents. We present a detailed P ...
-
(2003)Despite the various opening models of the southwestern part of the East Sea (Japan Sea) between the Korean Peninsula and the Japan Arc, the continental margin of the Korean Peninsula remains unknown in crustal structure. ...
-
(1999)Wide-angle seismic reflection/refraction data, recorded on ten seismographs from five large explosive charges, clearly define the crustal and upper mantle velocities of the Makarov Basin. These data are combined with a ...
-
(2001)Integrated analysis of the gravity data measured in the northern Baltic Sea in 1997 and the near-vertical BABEL data shot in 1989 provides important constraints for the Subjotnian (1600–1500) rift-related evolution of the ...
-
(1988)The Obruchev Rise is located near the junction of the Kurile-Kamchatka and Aleutian trenches. Continuous seismic profiling (CSP) has identified the structure of the sedimentary cover and the variations in its thickness. ...
