Provenance and tectonic setting of the Mesozoic to Cenozoic sedimentary rocks around the western Bogeda Mountains, Xinjiang

The integration of petrological, trace element and rare earth element analysis for the Jurassic to the Palaeogene sedimentary rocks around the western Bogeda Mountains, Xinjiang shows that the source rocks of the sedimentary rocks should be derived from the upper crust, and consist dominantly of felsic rocks with the mixtures of andesitic and basic rocks. The tectonic settings of the provenance should be represented by the magmatic arcs and recycled orogens. The results of research in this study may provide essential provements for the study of tectonic evolution and attributes of the provenance of the Jurassic to the Palaeogene sedimentary rocks around the western Bogeda Mountains, and thus are of great significance to the oil and gas exploration in the Junggar Basin, Xinjiang.
