| 英文摘要 | The beilekuduk syenogranite pluton is located in the beilekuduke alkali-rich granite belt, east junggar. this alkali-rich granite belt is composed of syenogranite, arfvedsonit granite and riebeckite granite plutons. shrimp u-pb dating for zircons from the beilekuduk syenogranite pluton yielded a (206)pb/(238)u age of 306 +/- 5 ma, suggesting that the emplacement of the pluton occurred at the end of the late carboniferous. on the basis of this new shrimp zircon u-pb age, combined with the zircon u-pb ages of the granite belt reported in the literature, the beilekuduk alkali-rich granite belt is determined to be terminal late carboniferous to initial early permian (307 similar to 290 ma) in age. geochemically, the beilekuduk syenogranite is enriched in silica, alkalis, ree, rb, th, ce, nd and hf and depleted in ba, sr, p, ti, eu, nb and zr and exhibits lree enrichment and a strong eu negative anomaly, with (ga/al) x 10(4) = 4 to 4.1, showing the features of an a(2)-type granite. it formed in an extensional environment during the post-collision stage, immediately following the orogenic movement. |
