鄂东南成矿区壳幔结构及其特征

Crust-Mantle Structure and Characteristics of Southeast Hubei Metallogenic Province

鄂东南成矿区壳幔具有典型的层状结构，各层具有鲜明的地质、地球物理和地球化学特征。硅镁层为地球形成时的原始地壳，硅铝层和上构造层为地球形成后膨涨增生而成。建立了壳、幔结构综合理想模式。

Crust-Mantle of Southeast Hubei Metallogenic Province possesses a typical layered structure.Each layer is characertistic of itsgeolgy,geophysics and geochemisty. Si-Mg layer is the original crust which was formed during thde earth formation,Si-Al lay-er and upper tectonic layer was formed after the earth formation.The ideal synthetic model of crustmantle has been outlined.
