摘　　要：中国东部处于亚洲东部巨型裂谷带的成矿背景,受太平洋板块俯冲、岩石圈不连续、岩石圈地幔减薄及花岗岩大火成岩省诸因素的影响,因蘑菇云状亚热幔柱动力学机制的制约,形成大规模成矿成藏作用。文章对东北、华北及华南3个地幔亚热柱的控矿作用的分析,为今后深部找矿和找藏工作提供了地质理论依据。East China is under minerogenic background of huge rift system of East Asia and is influenced by such factors as subduction of the Pacific plate,discontinuous lithosphere,thinning of mantle under the lithosphere,big granitic rock province etc.and is constrained by dynamic mechanism of mushroom-like sub-mantle plume thus large scale metallogeny and oil-gas reservoirs occur here.This paper analyzes mineral resources-control factor of sub-mantle plume structures in Northeastern China,Central China and Southern China so as to provide theoretical basis for future mineral and reservoir exploration to depth in the areas.
