(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(2001)The thermal thickness of Precambrian lithosphere is modeled and compared with estimates from seismic tomography and xenolith data. We use the steady state thermal conductivity equation with the same geothermal constraints ...
-
(2004)Chloritized annite from the Irizar granite has been used for laser-heating experiments, following the procedures used for 40Ar-39Ar dating (heating steps in the 600-1080 °C temperature range). Four runs, at different ...
-
(2002)Variations in mantle temperatures cause changes in seismic wave speeds and changes in the pressure at which mineralogical reactions occur, changing the depth at which a seismic discontinuity occurs. As an experiment in ...
-
(2004)Hazardous gravitational collapses involving hot lava domes can be triggered by intense rainfall, both in periods of active dome growth and volcanic repose. The collapses can evolve into energetic failures involving as much ...
-
(1999)We studied for the first time the effects of low-temperature plasticity on the formation of shear zones. A thermal-mechanical model has been developed for describing the shear deformation of Maxwell viscoelastic material ...
-
(1998)Thermal-neutron fluences in soil are reported for selected fast-neutron sources, selected soil types, and selected irradiation geometries. Sources include 14 MeV neutrons from accelerators, neutrons from spontaneously ...
-
(2001)Intra-continental deformation of soft zones during continental collision requires weak continental lithosphere which is able to be shortened across considerable width during later convergence. This enables significant ...
-
(2003)We present the results of a thermo-mechanical modelling study carried out to investigate the effect of pre-rift rheology on subsequent basin (de)formation in the Black Sea area. Important differences are inferred for the ...
