Abstract

The lithophile trace and major element characteristics of the upper mantle reflect crystal/liquid fractionations at high temperatures in the interior of a global magma ocean in the Earth. The combined evidence from the lithophile and siderophile elements in the mantle is indicative of a substantially molten Earth at the end of accretion. Thus, the geochemical data from the mantle support the modern theories of planetary accretion which require an initially molten Earth. © 1992.
