- Abstract:
- Multiple deposits of Cu-Pb-Zn-celesite-U-gypsum-coal-gas are enriched in mosaic tectonics of Mesozoic to Cenozoic basin-mountain-plateau, the western Tarim Basin, which is the special intracontinental mineralization element in China. Guided by metallogenic system theory and theory of wave-mosaic tectonics, based on the method of tectonic lithofacies, the matter-time-space patterns for glutenite-type Cu-Pb-Zn-celesite-U-coal metallogenic system were studied in order to better understand regional metallogenic regularities for this special intracontinental mineralization element. According to the sequences and combinations of tectonic lithofacies, prototype basin and basin dynamics, the glutenite-type Cu-Pb-Zn-celesite-U-coal metallogenic system in the western Tarim Basin may be classified into Yanshanian metallogenic sub-system of Cu-polymetallic-U-coal, Late Yanshanian-Early Himalayan metallogenic sub-system of Pb-Zn-celesite-U, and Late Himalayan metallogenic sub-system of Cu-U. Their matter-time-space distributions might be obviously controlled by the compression-extension converting basin in the mosaic tectonics of basin-mountain-plateau, the western Tarim Basin. Yanshanian metallogenic sub-system of Cu-polymetallic-U-coal is located in Cenozoic intracontinent apart-pulled basin, and is synthetically controlled by hedge-type base-involved fold-and-thrust slice, ruched multiple syncline and intrusive tectonic system of gabbro-diabase dykes. They are formed during the stage of basin-positive-inversion, and coupled by positive inversion by thermal materials derived from the upper mantle. Whereas, Late Yanshanian-Early Himalayan metallogenic sub-system of Pb-Zn-celesite-U is located in Cretaceous to Palaeogene compression-extension converting basin, and is synthetically controlled by rear-propagation base-involved fold-and-thrust slice at the southern edge of the southwestern Tianshan, Wulagen inclined synclina and interlayer slip structure. The glutenite-type Pb-Zn-U deposits form during the peak stage of basin-positive-inversion; however, the celesite deposit forms during the beginning stage of basinnegativeinversion. Nevertheless, Late Himalayan metallogenic sub-system of Cu-U is located at Mesozoic intermountain enclosed salted-lake-basin, and is controlled by fold-and-thrust slice belt with piggyback propagation and thin-skin type.
