| Abstract: | The Gejiu superlarge tin polymetallic deposit is located in the southeastern part of Yunnan Province,China,which comprises five separate orefields:the Malage,Songshujiao,Gaosong,Laochang and Kafang orefields. The pre-Triassic and Early Triassic sedimentations were marine source predominated,and shifted to terrestrial source dominated after Early Triassic. Multiple periods or stages of magmatic activities ranging from Proterozoic to Cenozoic along with main tectonic movements were recorded in the area. This ... |
