(2001)The terrestrial heat-helium imbalance [O'Nions and Oxburgh, Nature 306 (1983) 429-431] is based on the observation that significantly less 4He is released from the Earth's mantle than is predicted from the radiogenic element ...
-
(2000)Equilibrium lithospheric geotherms are generally assumed to have a self-similar shape with a nearly linear thermal gradient in the upper portions of the thermal lithosphere and a smoothly decreasing gradient in its lowermost ...
-
(2002)The global heat flow is the surface representation of thermal processes within the earth's mantle. The long-wavelength pattern of observed heat flow closely resembles the plate tectonics and its most prominent feature is ...
-
(1999)The objective of this paper is to quantitatively assess the role of mantle plumes in transporting heat to the base of the lithosphere. We first review the mechanisms responsible for mantle heat flow. We take the total ...
-
(1997)Hydrothermal convection in the upper oceanic crust has been inferred to be a globally common and important process. Under the simplest conditions of planar boundaries, lateral dimensions of convection cells provide a strong ...
-
(2002)Marine heat flow data, obtained with a Lister-type probe, consists of two temperature decay curves, frictional and heat pulse decay. Both follow the same physical model of a cooling cylinder. The mathematical model describing ...
-
(2000)Large-scale, lateral fluid flow through oceanic crust provides an explanation for regionally low heat flow in several seafloor settings. A well-mixed aquifer (WMA) model provides a quantitative and conceptual tool for ...
-
(2002)A new probe for autonomous high precision temperature measurements in deep sea sediments has been developed by Fa. Antares and the University of Bremen and extensively tested during several expeditions. The miniaturized ...
-
(2002)The distribution of the heat producing elements within the lithosphere provides an important control on continental thermal regimes and the mechanical strength of the lithosphere. Moreover, the strong temperature dependence ...
-
(2001)The dynamic coupling between plate motion and mantle convection is investigated in a suite of Cartesian models by systematically varying aspect ratios and plate geometries. The aim of the study presented here is to determine ...
-
(2003)The geological record indicates that stages of relatively steady plate motion have been punctuated by comparatively brief periods in which plate velocities have reorganized. The distribution of buoyancy sources in the ...
-
(1996)The most common model used for representing the evolution with age of the oceanic lithosphere is the 'plate model' where the temperature is set at a fixed depth, called the base of the plate. This 'base of the plate' has ...
-
(2004)We discuss two types of physical constraints derived from thermodynamics that can be applied during seismic inversions. The first constraint involves assimilating heat-flow measurements in seismic inversions. This can ...

(2005)На континентальной территории Восточного Китая тепловой поток варьирует в интервале 26- 106мВт/м2 со средним значением 61+2мВт/м2. Здесь выделяются 4 кайнозойские рифтовые зоны, входящие в западную и восточную рифтовые ...
