河淮地幔亚热柱的隆升，使岩石图发生强烈减薄的同时，地幔物质呈蘑菇状向外围造山带之下拆离。当幔源拆离薄层被造山带陡倾韧性剪切带切割造成减压释荷，使韧性软化岩石转变为深熔岩浆上侵，形成沿造山带轴部展布的点状或线状构造岩浆带，表现为以构造岩浆带为核部的隆升构造一幔枝构造。隆升较快的构造区段上覆盖层里揭顶式大幅度拆离，形成典型的变质核杂岩构造。地幔亚热柱→幔枝构造→变质核杂岩演化过程控制着成矿物质的运移、聚集、成矿作用，并在幔枝（变质核杂岩）构造的不同部位形成不同的矿床类型。
The uplifting of the Hehuai mantle plume, making the rock diagram strongly thinned at the same time, the mantle material was mushroom-like detachment to the periphery of the orogenic belt. When the mantle source detachment thin layer is cut by the steep ductile shear zone of the orogenic belt, the decompression and release load is caused to transform the ductile soft rock into deep lava to invade and form a point-shaped or linear structure distributed along the axis of the orogenic belt Magmatic belt, the performance of the magmatic belt as the core of the uplift structure of a mantle structure. The uplift of the overburden in the uplifted tectonic segment was largely detached to form a typical metamorphic core complex structure. The mantle plumes → mantle structure → metamorphic core complex control the migration, accumulation and mineralization of ore-forming materials, and form different deposit types in different parts of the mantle (metamorphic core complex) structure.
