An incandescent gas mantle, gas mantle or Welsbach mantle is a device for generating incandescent bright white light when heated by a flame. The name refers to its original heat source in gas lights which illuminated the streets of Europe and North America in the late 19th century. Mantle refers to the way it hangs like a cloak above the flame.

Energetics of mantle convection and the fate of fossil heat

Apr 26, 2003 [1] Reconstructing the thermal history of the Earth, consistent with the low concentration of heat-producing elements in convecting mantle as well as with modest secular cooling required by geological records, has been a major challenge in geophysics and geochemistry. By developing the self-consistent energetics of plate-tectonic mantle …

Thermal evolution of Earth's mantle and core: Influence of

In a series of studies on the thermal evolution of Earth’s mantle and core [Nakagawa and Tackley, 2004; 2005; 2010], we have assumed a reference viscosity (at T=1600 K and P=0) of 1022 Pa.s and a concentration of radioactive elements based on the surface heat flux of the Earth’s mantle (6x10-12 W/kg). In addition, the initial mantle temperature in these studies was …

Earth Mantle - an overview ScienceDirect Topics

Introduction. Earth's mantle plays an important role in the evolution of the crust and provides the thermal and mechanical driving forces for plate tectonics. Heat liberated by the core is transferred into the mantle where most of it ( 90%) is convected through the mantle to the base of the lithosphere. The remainder may be transferred upward ...

It is even more unlikely that areas of high concentration develop within the mantle. Thus, concentrations of radioactive elements is not likely to cause melting. Frictional Heat - In areas where rocks slide past one another, such as at the base of the lithosphere, on at subduction zones, heat could be generated by friction. Get Details

Energetics of mantle convection and the fate of fossil heat

mantle can yield a geologically reasonable solution in the thermal evolution model of the Earth. The effect of dehydration on mantle rheology during plate formation with mantle melting results in more sluggish plate tectonics (i.e., lower heat flow) for hotter mantle. This inverse relationship between mantle temperature and surface heat
