| 英文摘要 | The Mengxi Cu-Mo deposit located north to the contact zone of Qiongheba granite batholith at the eastern segment of Beitashan-Qiongheba are, eastern Junggar, is characterized by strong alternation, development of fracture-filled veins, and vertical zoning of veins with various mineral composition, and is kind of porphyritic Cu-Mo deposit strong affected by fault structures in the ore district. Diorite porphyries and feldspar porphyries are ore-forming porphyry, in the Mengxi Cu-Mo deposit. Granite in the Qiongheba area are cale-alkaline, and characterized by high Ph, K, Sr, U, Th and Zr, low Rb, Nb, Y, Ta, Yb and Ti, enriched LREE with (La/Yb)(N) value from 3.1 to 15.5. All the 22 analyzed intrusive samples have plots in the VAG (volcanic arc granite) domain in diagrams of Rb-Y + Nb, Nb-Y, Rb-Ta + Yb and Ta-Yb, and similar trace element and REE spiders with that of continental are volcanic in Andes. These granite were production of continental arc magmatism with a composition containing component from the Upper, middle and lower continental crust and equal to the average of continental arc volcanic rocks in Andes. Result of Re-Os dating shows that both the molybdenite and Cu-Mo deposit in the Mengxi area were formed at about 411 Ma BP, the diorite porphyries and feldspar porphyries in the Mengxi ore district and granite in the Qiongheba area were possible formed at latest Silurian- earlist Devonian. This indicates that Yemaquan-Beitashan- Qiongheba porpbyries and porphyry copper mineralization belt is most likely the western extending of the the Oyu Toigoi Silurian-Devonian porphyry copper mineralization belt. The granite belt in the Qiongheba area, as a part of Paleozoic continental are magmatic bell, is a potential target for porphyritic CU deposit. |
