摘要
广东凡口铅锌矿田的构造体系比较复杂,争议大。为了查明其构造体系,应用地质力学的理论和方法,对凡口铅锌矿田内各类构造结构面力学性质进行了鉴定。结果表明,矿田内构造形迹有三种类型的构造体系,即大致成生于加里东—海西期的北西构造带、大致成生于印支—燕山期的入字型构造和大致成生于喜山期的东西构造带,这对于凡口铅锌矿田的深边部找矿具有一定的指导作用。
Structure system of Fankou lead-zinc deposit in Guangdong province is complex and has been argued about for years.In order to find out structural system in the ore-field,on the basis of the theory and method of the geomechanics,the mechanics features of structural planes of the structures of Fankou lead-zinc ore-field have been identified.It＇s indicated that its structure is divided into three types of systems,that is,the NW trending tectonic belt which origin from the Caledonian stage into the Hercynian stage,the lambda-type structure which origin from the Indo-Chinese stage into the Yanshan stage and the EW trending tectonic belt which origin from the Himalayan stage,which has definite guiding role in deep and edge prospecting in Fankou lead-zinc ore field.
