Abstract: The ophiolite migmatitic complex is in Hong shishan deep hugerift of the north margin of Tarim slab. It formed in the environment of the small ocean basin for its constitution of material in the later Early Carbon iferous. And by reform of a tleast three stage structural deformation metamorphism,it returned to terrene by shearing at the Late Permian. The authors discuss constitution and deformation metamorphic characteristics in Hongshishan region,and provide the recently material for the researching of the north belt of Beishan.
