摘要
韧性剪切带为二甲金矿的控矿构造.剪切带内的构造岩具有良好的分带性.韧性剪切带的变形变质作用伴随化学组分的变化、围岩蚀变具多样性.构造变形,围岩蚀变型式及共强度与金矿化类型之间具有密切的对应关系.
Ductile shear zone is an ore-conirolling structure in Erjia gold deposit. Well developed zoning is found in tectonite in the ductile shear zone where the dcformation-metamorphism makes the chemical compositions change with variety of wall rock alterations in this area. The close relationships among deformation intensity and wall rock alteration pattern and gold mineralization type arc described.
