-
(2004)The ascent history of the Horoman peridotite complex, Hokkaido, northern Japan, is revised on the basis of a detailed study of large ortho- and clinopyroxene grains 1 cm in size (megacrysts) in the Upper Zone of the complex. ...
-
(2003)Thermal infrared emission and reflectance spectra (250-1400 cm(-1); similar to7-40 mum) of experimentally shocked albite- and anorthite-rich rocks (17-56 GPa) demonstrate that plagioclase feldspars exhibit characteristic ...
-
(1985)Many regions of recent tectonic activity are characterized by the existence of mantle inhomogeneties which are revealed by various geophysical methods. It is found that the lithosphere beneath the continental rifts and ...
-
(2004)Pacific plate subduction at the Aleutian–Kamchatka juncture, or corner, could be accommodated by either a large bend or a tear in the oceanic lithosphere. In this paper, we describe a number of observations which suggest ...
-
(2004)Two-dimensional thermal modeling of the subduction and exhumation of the ultrahigh-pressure (UHP) Maksyutov Complex in the south Ural Mountains tests factors influencing the low modern heat flow in the Urals and the feeble ...
-
(2000)Long-term thermal modeling of volcanoes using satellite imagery provides an effective tool for monitoring remote yet dangerous volcanoes in the North Pacific. This region includes volcanoes in Alaska, the Aleutian Islands, ...
-
(1998)Using X-ray diffraction with synchrotron radiation, we have studied the pressure changes induced by laser heating on samples compressed in a diamond-anvil cell. The method has been to compare experimentally observed phase ...

(PANGAEA, 1984-03-19)
-
(2002)Large-scale crustal thickening by tectonic and/or magmatic processes can lead to various complex patterns of multi-layered continental crust, It is well-known from one-dimensional thermal modeling that variations in total ...
-
(Федеральное государственное бюджетное учреждение науки Геофизический центр Российской академии наук, 2016)The study of collision structures is conducted based on the complex model of the thermal and mechanical evolution of overthrusting process for the rheologically layered lithosphere, which includes brittle upper crust and ...
-
(2001)The thermal dependence of the structure of natural phengite-2M1 with chemical formula situ neutron diffraction. The short-range correlated behaviour of the hydroxyl group was probed by FTIR spectroscopy while the long-range ...
-
(1993)Numerous petroleum-geochemical analyses of deeply buried, high-rank, fine-grained rocks from ultra-deep wellbores by different investigators demonstrate that C15+ hydrocarbons (HCs) persist in moderate to high concentrations ...
-
(2003)The thermal state of lithosphere in Mongolia has been modeled on the basis of measured regional heat flows and predicted temperatures at depths from 0 to 50 km. The highest temperatures of 1100-1200 C and heat flows of ...
-
(PANGAEA, 2010-09-13)The results of the International Permafrost Association's International Polar Year Thermal State of Permafrost (TSP) project are presented based on field measurements from Russia during the IPY years (2007-09) and collected ...
-
(2002)Microstructure-based finite element simulations were used to study the thermo-mechanical behaviour of calcite and dolomite marbles. For a given mineral microstructure, thermal stresses and elastic strain energy varied with ...
-
(PANGAEA, 1997-04-05)
-
(2000)Results from seismic tomography provide information on the thermal structure of the continental upper mantle. This is borne out by the good agreement between tectonic age, surface heat flow and a tomographic S-wave velocity ...
-
(1998)Global compilations of surface heat flow data from stable, Precambrian terrains show a statistically significant secular change from 41±11 mW/m2 in Archean to 55±17 mW/m2 in Proterozoic regions far removed from Archean ...
-
(1995)The recent review by Marshall (1994) of the production of amino acids from the interstellar components, formaldehyde and ammonia, is placed in the larger context of the origin of life. Thermal energy, being ubiquitous in ...
