一个褶皱控矿的典型——厚婆坳银多金属矿床成矿构造浅析

A Typical Example of Mineral Deposits Controlled by Folding——Analysing on the Metallotectonics of Ag-Polymetallic Deposit at Houpoao

广东潮州厚婆坳银多金属矿床,是一个成矿裂隙严格受褶皱控制的典型。矿区内含矿裂隙带与褶皱要素,如层面、劈理面、轴面、枢纽以及某些显微构造等,具有密切的空间展布和相同的应力与应变关系,褶皱构造地球化学控制成矿逆分带。文中讨论成矿构造展布规律与找矿的指导意义。

The Ag—Polymetallic deposit at Houpoao of Chaozhou,Guangdong Province,was a typical case in whichmetallogenetic cracks were strictly controlled by folding.In the field,there are close spaoe configuration and identicalstress-strain relationship between orebearing crack belts and folding elements,the elements include bedding plane,cleavage,axial plane,hinge and some microstructures etc.The inverse zoning of ores was dominated by the geochemistry of foldtectonics.The space configuration of metallotectonics and its significance in prospecting are discussed in this paper.
