Proterozoic copper metallogenic framework and geochemistry steep zone in central Yunnan Province

摘要

The wildly horizontal and vertical chemical heterogeneties, which result from the inchoate core-mantle differentiation of the globe and the spatio-temporal difference of various regions in the globe, bring on the mantle and crust from different landmass and oceans with markedly elemental and isotopic signatures. Weherefore these signatures could be used to differentiate the attribute from various landmass or oceans and recover the scent of kinematics and chemical geodynamics process. It is a quantificational method compared with the division by geotectonics facies and plaeontologic fauna.
