Composition and Equation of State of the Lower Mantle from the p VT Data of Perovskite

摘要：

@@ For the earth”s lower mantle, a long-standing issue is whether it has a composition similar to that of the upper mantle represented by Ringwood”s py-rolite model. Although a homogeneous mantle issupported by geophysical studies, and also used as an apriori assumption to estimate the composition of the bulk silicate earth (BSE) or primitive mantle( PM), it is inconsistent with a number of geochemi-cal observations.
