| 英文摘要 | Yemaquan granitic pluton in east junggar of xinjiang is a granitic complex, which dominantly consists of granodiorite, monzogranite, and alkali-feldspar granite. these rocks have nearly coincident zircon u-pb ages (similar to 300ma) within errors, suggesting that this pluton was emplaced in late carboniferous by the post-collisional magmatic activity in east junggar. the geochemical compositions show that all of these rocks are metaluminous, and their major elements and trace elements, such as cao, al(2)o(3), na(2)o, k(2)o, rb, sr have obviously linear relationship with sio(2). all these rocks display similar characteristics in incompatible-element spidergrams and bee patterns, and with sio(2) content increasing, their negative eu anomalies become stronger. in addition, in situ hf isotope analysis of zircons reveal that the rocks in the yemaquan pluton have much close hf isotopic compositions, their epsilon(hf)(t) values ranging from +11. 8 to +12. 7. according to the age and geochemical characteristics, we argue that the yemaquan granitic complex was probably formed by the same magma which experienced some evolution. |
