Internal Structure and Assemblage Features of Tectonic Slices in Dong Cuo Melange Zone

Abstract

In order to make a thorough study of the Dong Cuo melange zone,the authors used remote sensing interpretation to divide the Dong Cuo melange zone into three secondary tectonic slices belts,and found that the three belts extend nearly in parallel in the plane,converge eastward and westward,and thrust southward one by one in profile.Field investigation shows that the interpretation results are in accordance with the practical situation,and the material composition and geometric structure of rocks in various slices are different.The ophiolite melange belt is the main belt in the Dong Cuo melange zone.
