| Abstract: | The Gejiu superlarge tin-copper polymetallic deposit,located in southeastern Yunnan Province in China,consists of few separate ore fields,for instance,the Malage,Songshujiao,Gaosong,Laochang and Kafang ore fields.This article focused on the study of lithofacies sequence of sedimentary rocks,volcanic rocks,and volcanic sedimentary rocks in the Gejiu superlarge tin-copper polymetallic deposit,as well as the western Guangxi Zhuang Autonomous Region.The tectonic lithofacies analysis and reconstruction of tecton... |
