摘　　要：提出了超高构造变质流体的概念及特征，指出该类流体富含气液及贵金属络合物，主要产生并活动于韧性剪切带，在剪切带由压扭性向扭张性转化过程中，该流体发生浆、液、气分异而充填交代成矿。This paper poses a conception of superhigh tectonometamorphic fluid,i.e.it is a mixture of magma,liquid and gas produced in the superhigh dynamic metamorphic action.The author points out this fluid is rich in gaswater and noble metal′s complex.Such fluids occur and act mainly in some ductile shear zones.When those shear zones change from compressoshear to tensile shear,the fluids are differentiated into magma,liquid and gas,and occur fillingreplasement mineralization.
