This paper documents the geochemistry of clastic sedimentary rocks from the Upper Carboniferous Zongwulong Group in the Zongwulong structural belt of the Qaidam Basin, NW China, in order to trace the sources of the sediments and to understand their tectonic settings at the time of deposition of the Zongwulong Group. Although the major elements differ among different samples, their low mean chemical...
Two important geological issues have a long history of debate in the Xingmeng area. The first concerns the final closure of the North China plate, Siberia plate and several intermediate massifs in the area, and the other concerns the folding and lifting of the Xingmeng Trough. Disagreements arise because of issues involving the tectonic-palaeogeographical environment of the Upper Permian deposits...
