| 摘 要： | 塔里木盆地库鲁克塔格地区新元古代冰碛岩剖面是目前世界各大陆中唯一发育有4套新元古代冰碛岩和多期火成岩事件的剖面。近年来。“雪球事件”的提出为全球新元古代冰碛岩的研究注入了新的活力，各国地质学家根据新元古代冰碛岩在全球各大洲发育的特点、同位素年龄扣C／O、Sr同位素在新元古界划分出4个冰期。因此，新疆库鲁克塔格地区新元古界发育的4套冰碛岩的沉积特征、沉积环境和年代地层学研究的进展始终为各国地质学家所注目。本次获得的库鲁克塔格地区特瑞爱肯组的锆石SHKIMPU-Pb新年龄．为完善库鲁克塔格地区新元古代冰碛岩的年代地层学提供了新的证据。

| Abstract: | Neoproterozoic glaciations of Quruqtagh area in Tarim basin are recognized, four of which appear to be global and with different volcanic rocks. In recent years, ＂Snow earth＂ hypothesis put forwards to the study of glaciation, any advancement of sedimentary, depositional environment and glaciation chronostratigraphic dating for the four glaciations in Quruqtagh area in Tarim basin, which will put more attention to global. This paper gives a new zircon SHRIMP U-Pb dating to be showing an evidence for the Neoproterozoic glaciations of Quruqtagh area in Tarim basin. |
