摘　　要：断层岩具有构造-化学二重性,断裂混合岩是一种更深位的断层岩.由此,R.H.Sibson提出的断层(岩)垂直分带双模式,可扩展为垂直构造地球化学分带三模式.自上而下为:碎裂岩带;糜棱岩带;断裂混合岩带.不同的带有不同的变形-地球化学特征和成矿专属性.Fault rocks have a double property, structural and geochemical, while fractured migmatites are considered as kind of deep seated fault rocks. In view of this, the bimodal of fault rocks advanced by Sibson^([2]) may be developed into a trimodel of structural-geochemical zonation as cataclasite, mylcnite andfractured migmatite zones from top to below. Different rock zonations have different deformational-geochemical features and metallogenic attribute property.
