摘要
本文主要介绍大多数层控铅锌矿床是产在半封闭沉积盆地碳酸盐岩中,属同生沉积成因。在地台活化时期,由于扬子地台西南缘从稳定地块转向活化。在构造-岩浆作用时期,火山喷气导致了金属聚积。因此,所有的矿床均表现出受超壳大断裂控制,这些矿床可认为是同生沉积-火山喷气成因。
Most stratabound lead and zinc deposits occurs in carbonates,in semi-closed sedimentary basin. They are of syngenetic origin. In the period of mobilization of the South-western margin of Yangtzi Platform as a result of tectonicmagmatism ,the volcanic exhalation brought about the metal concentration. Thus,all of these deposits appear to be cutting crust deep-seated fault controlled. The deposits may be syngenetic sedimentary-volcanic exhalative in orighin.
