英文摘要 | The Baogutu large-scale porphyry copper deposit is located in the west margin of Junggar basin. Copper mineralization which mainly occurs as disseminated and veinlet- disseminated, is hosted by porphyritic ( quartz) diorite, diorite porphyrite, crypto-explosive breccia, minor in granodiorite. Based on cross-cutting relationships and mineral assemblages of the ore veins, the ore-forming process underwent three stages as follows; Biotite-potassic feldspar-albite stage, quartz-sulfide stage and quartz carbonate stage. The delta D(SMOW) values of quartz vein range from - 107 parts per thousand to - 86 parts per thousand, and the delta(18) O(SMOW) values range from 11.3 parts per thousand to 16.2 parts per thousand, with corresponding delta(18)O(H2O) values range from 4.4 parts per thousand to 9.3 parts per thousand. The combined isotopic data suggested that the ore-forming fluids were derived from deep-seated source magmatic water. The delta(34)S values of sulfide range from -5.1 parts per thousand to 0.77 parts per thousand with an average of -1.8 parts per thousand, indicating that the sulfur in the fluids was derived from deep-seated magma or the mantle. Combining LA-ICP-MS zircon U-Pb dating on the II, III and V magmatic body and the Re-Os dating on molybdenite, we suggest metallogenesis of the Baogutu porphyry copper deposit took place in the Late Carboniferous, and its mineralization is closely related to the intruding of the intermediate-acid porphyry body. |
