豫南熊店高压变质岩块体经历了6期变形和变质作用,即从深地壳层次挤压缩短体制下的不均匀韧性剪切、榴辉岩进变质作用,到中地壳层次挤压体制下的逆冲推覆、钠长绿帘角闪岩相退变质作用,到地壳浅层伸展体制下的脆性—韧性滑脱、绿片岩相变质作用,以及更浅层次的脆性变形,动力变质作用。高压变质岩的形成与向地壳中、浅层次的大幅度抬升均是在挤压机制下韧性变形作用的结果,而高压变质岩暴露到地表是伸展滑脱、断块升降和差异抬升所致。
The high-pressure metamorphic rocks in Xiongdian area of South Henan underwent the deformation and metamorphism of six stages, that is, the inhomogeneous ductile shear under eclogite crustal shortening system and the metamorphic effect of eclogite into the crustal crustal extrusion system , The metamorphic action of the albite amphibolite rocks to brittle-ductile detachment, greenstone facies metamorphism and more shallow brittle deformation and dynamic metamorphism under the shallow extensional crustal system. The formation of high-pressure metamorphic rocks and the substantial uplift to the middle and shallow crust are the result of the ductile deformation under the compression mechanism. However, the high-pressure metamorphic rocks are exposed to the surface due to the extension and desquamation, the rise and fall of the fault blocks and the differential uplift.
