| 英文摘要 | Western Junggar in China and Circum-Balkhash in Kazakhstan are located in the central section of the central Asian metallogenic domain. A number of the super large- and large-sized porphyry copper deposits well developed in this domain and comprise the most important concentration region of the porphyry copper deposits. Their mineralization dynamic setting has no significant difference. Their ore-bearing magma series and materials source are slightly different. These result in the formation of the porphyry copper deposits with slightly differences. The porphyry copper deposits occurred in the western Junggar is the Baogutu deposit which is located in the southern part of the Carboniferous Darbut immature arc. The host magma is the intermediate calc-alkaline series and emplaced at unusually depth (5 similar to 10km). The ore-forming materials derived from the mantle based on the values of the S (delta(34) S = -2. 4 parts per thousand similar to 0. 4 parts per thousand) and Pb ((206)Pb/(204)Pb = 17.92 similar to 18. 89, (207)Pb/(204) Pb = 15.45 similar to 15. 62, (208)Pb/(204)Pb = 37.68 similar to 38. 36). The host stocks are the intermediate complex which consists of the early main diorites and quartz diorites, and minor late diorite porphyries. The host stocks have been overprinted by basic (biotite-quartz and chlorite-epidote) and minor acidic (quartz-sericite) alteration assemblages where a predominance of disseminated mineralization together with lesser amounts of vein mineralization occurred. The porphyry copper deposits occurred in the Circum-Balkhash are the Kounrad and Aktogay deposits which are located in the northern part of the Late Paleozoic Balkhash-Yili magamtic are. The host magma is the intermediate-acidic calc-alkaline series and emplaced at shallow depth. The ore-forming materials derived from both mantle and crust based on the values of the S (delta(34) S =0. 7 parts per thousand similar to 6. 0 parts per thousand) and PI) isotopes. The host stocks are the intermediate-acidic complex which consists of the gabbro, diorite, quartz diorite, granodiorite and plagiogranite. The host stocks have been overprinted by prominent acidic (advanced argillation, quartz-sericite) and rare basic (K-feldspar-biotite-quartz) alteration assemblages in the Kounrad and main basic (K-feldspar-biotite-quartz) and minor acidic (quartz-sericite) alteration assemblages in the Aktogay. They well develop the disseminated and vein mineralization. |
