COMPARATIVE DEGASSING HISTORY OF EARTH AND VENUS. S. Franck and C. Bounama,
Introduction: Parameterized convection models have provided important results for the thermal history of the Earth and of other planets [1,2,3]. Schubert et al. [4] calculated a secular cooling of about 150°C-300°C since the Archaean and showed that a substantial portion of the present terrestrial heat flux is primordial with a Urey ratio of 0.65 to 0.85. For the first time Jackson and Pollack ...
متن کاملRanges of Atmospheric Mass and Composition of Super-earth Exoplanets
Terrestrial-like exoplanets may obtain atmospheres from three primary sources: capture of nebular gases, degassing during accretion, and degassing from subsequent tectonic activity. Here we model degassing during accretion to estimate the range of atmospheric mass and composition on exoplanets ranging from 1 to 30 Earth masses. We use bulk compositions drawn from primitive and differentiated me...
متن کاملThe xenon record of extinct radioactivities in the Earth.
Analyses of xenon from well gas rich in carbon dioxide reveal a large excess of radiogenic xenon-129 from the decay of extinct iodine-129. Smaller excesses observed in the heavy xenon isotopes are from fission. These results place narrow limits on any age difference between the earth and the oldest meteorites. The occurrence of excess radiogenic xenon-129 in well gas also suggests that any quan...

متن کاملThe Effect of Depth-dependent Viscosity on Convective Mixing in the Mantle and the Possible Survival of Primitive Mantle
The effect depth-dependent viscosity has on convective mixing and sampling (or degassing) of primitive mantle beneath ridges is explored in two-dimensional models. Higher relative viscosities in the deep mantle decrease convection velocities and strain rates and prolong the residence time of material in the deep mantle. If the average viscosity of the lower mantle is at least 100 times the visc...
