| 英文摘要 | The Dajiashan alkali granite is situated at the central parts of the Kalameili-Haerlike granitic belt of Eastern Junggar, Northwest China. LA-ICPMS zircon U-Pb dating shows that its crystallization age is 284 +/- 1Ma. The Dajiashan alkali granite is characterized by high absolute SiO2, Alkali (A/CNK < 1,AR =3. 9 similar to 6. 67) abundance, low CaO and Al2O3 high FeOT/MgO and 10000 * Ga/Al ratios; enriched REE (except Eu), LILE (Rb, U, Th, K) and some HFSE (Zr, Hf, Nb, Ta) strongly depleted Ba, Sr P, Ti, Eu; Y/Nb (2.71 similar to 3.75) > 1.2. All these facts reveal that the Dajiashan alkali granite is a Permian A(2)-type granite. The distribution of ages of the other A-type and late-orogenic granites belts in the Eastern Junggar area indicates a south-ward younging trend, which is good agreement with the south-ward accretion. |
