Reconciling Mantle Rare Gas Geochemistry with Tomographic Evidence of Whole Mantle Convection
Mineralogical Magazine, 1998High-resolution seismic tomography clearly shows that lithospheric plates penetrate the 670 km discontinuity (e.g. van der Hilst et al, 1997). A common view defended by geochemists (Turekian, 1959; Allbgre et al. , 1996) holds that the isotopic composition of He and Ar is incompatible with geophysical evidence because (a) the inventory of terrestrial ...

Isotope and Trace Element Geochemistry of the Earth’s Mantle
1979Chemical and isotopic information about the Earth’s mantle can be obtained from several sources, but all require certain assumptions: 1. Chondritic Meteorites are assumed to represent primitive matter of the solar system. Chemical models for the mantle usually assume loss of volatile elements, possibly including alkalis, during and after ...
