Thermal regime of a downgoing slab

Tectonophysics, 1970
Abstract The thermal regime of a downgoing slab of lithosphere as implied by the global tectonic hypothesis is important for interpreting the geophysical data and for testing the hypothesis. Heat flow, seismic velocities, density, the occurrence of volcanoes and earthquakes are influenced by the temperatures. Using a finite difference solution of the

The Thermal Regime of Cryosols

2004
Cryosols are soils whose development is affected by permafrost, ground that remains frozen for two or more years (ACGR, 1988). Cryosols develop both within the active layer, the surface layer of the ground above permafrost that freezes and thaws each year (Muller, 1947), and in the upper portion of the permafrost. For the requirements of classification,

Thermal regime of a blast furnace

Metallurgist, 1987
A parameter analysis was made of blast furnace regimes: blast, charging, slag, and thermal. It was found that blast furnace efficiency could be increased by equipping the furnaces with computer control technology. A West Siberian metallurgical shop introduced an automatic data processing and control system which automatically controlled batching of ...

Thermal state and thermal regime of the Earth's interior

Physics of the Earth and Planetary Interiors, 1985
Abstract A simplified version of the thermal state and thermal regime of the Earth's mantle is given. It is supposed that the large-scale convection in the mantle is double-layered. Convection in the upper mantle is determined by heat flux from below, and in the lower mantle by internal heating. It is estimated that the thermal relaxation time of the

Thermal Regime of Bovan Lake

Proceedings Volume 3
<p>Bovan Lake is a reservoir in southeast Serbia, used mainly for water supply, flood protection and recreation. The purpose of this study is to better understand seasonal variations in water temperature by examining the thermal characteristics of the lake at various depths within the intake tower.

Thermal regime of brazing carbides

Journal of Engineering Physics and Thermophysics, 1994
A problem of unsteady thermal conductivity in a multilayer material with an internal heat source of variable power is solved. Using induction brazing as an example the effect of energetic, temporal, and geometrical parameters on the temperature field, temperature gradients, and rates of heating and cooling of materials, which provide the required ...

The Thermal Regime of Permafrost Regions

2014
The permafrost base is defined as 0 °C isotherm, and thickness is defined as the depth from the surface to that isotherm. Permanent ice is found on or beneath approximately 20 % of dry land: 75 % of Alaska, 63 % of Canada, and 47 % of the Russian Federation are covered by permafrost.

Thermal regime of the continental lithosphere

Journal of Geodynamics, 1984
From studies of the global heat flow data set, it has been generalized, with respect to the continental lithosphere, that there is a negative correlation between heat flow and the lithosphere's tectonic edge, and that the lithosphere's thermal evolution is similar to that of the ocean basins, resulting in a 'stable geotherm' in both environments. It is

Thermal Regime of a Prairie Snowcover

Soil Science Society of America Journal, 1977
Abstract An energy budget approach was used to study the melting of a shallow prairie snowpack. In the analysis, all the terms of the energy budget were determined independently. The major source of energy for the melt was the net radiation flux.

Lithospheric thermal regimes in Europe

Physics of the Earth and Planetary Interiors, 1993
Abstract The heat flow pattern of Europe, derived from more than 8000 observations, is dominated by a general northeast to southwest increase in geothermal activity, which is the consequence of the tectonic evolution of the whole continent. This paper reviews the history of the geothermal mapping of Europe, and describes the recently compiled set of ...
