广西某些内生金属的成矿期

THE MATALLOGENIC STAGES OF SOME ENDOGENIC METAL DEPOSITS IN GUANGXI

摘要: 本文依大地构造与成矿学的观点,将广西境内某些内生金属矿床划分为五个成矿期,即雪峰期、加里东期,海西期、燕山期和喜山期。并初步探讨了它们各自的时空分布及成矿特征。

Abstract: From the tectonic and metallogenic points of view, five metallogenic stages may be distinguished for some endogenic metla deposits in Guangdong and their respective temporal-spatial distribution and metallogenic features are discussed preliminarily. The Yanshanian stage was a peak stage of mineralization, and the deposits formed duing the stage are numerous in type, large in scale and widespread. Next come the Xuefengian and Caledonian metallogenic stages: the deposits formed in this stage are mainly distributed in northern and eastern Guangxi and dominated by tin, copper and gold deposits. Mineralizations in the Hercynian and Himalayan metallogenic stages ware generally weak.
