摘要

摘要: 沉积物的形成是地壳差异升降运动的物质记录.位于青藏高原北缘的酒西盆地晚新生代沉积比较敏感和全面记录了高原北部的构造运动和隆升过程.老君庙剖面晚新生代沉积物重矿物分析表明13 MaBP以来酒西盆地南部沉积物中重矿物具规律性变化;依据重矿物具规律性变化和沉积特征,揭示了青藏高原北缘晚新生代以来地壳运动经历了稳定期(13～8.26 Ma)、逐步阶段性隆升期(8.26～<4.9 Ma)和急剧强烈整体阶段性隆升期(>3.66～0 Ma)三个重大构造演化过程。

Abstract: Sediments in basins couId record the ascending and descending difference of the earth crust. The sediments of the Late Cenozoic in the Jiuxi basin,Iocated in the northern margin of the Tibetan pIateau,have sensitiveIy and com-pIeteIy recorded the upIifting process of northern pIateau. The heavy mineraIs of sediments have the reguIatory variety in the Laojunmiao section of Jiuxi basin since 13 MaBP；detaiIed study of the heavy mineraI has reveaIed four heavy mineraI stages of sedimentary evoIution. they are： ①stabIe heavy mineraI associations before 12.18 Ma BP, ②reIativeIy stabIe heavy mineraI associations between 12.18 and 8.26 Ma BP, ③ unstabIe heavy mineraI associations between 8.26 and 4. 9 Ma BP,and ④ the very unstabIe heavy mineraI associations since 3.66 Ma BP. The associated mountain erosion and u-pIift are suggested having experienced three phases on the upIifting process of the northern Tibetan PIateau,that is,tec-tonic stabIe （13 ~ 8.26 Ma BP） ,graduaI staggered upIift （8.26 ~ < 4.96 Ma BP） ,and rapid intense intermittent mass upIift（ > 3.66 ~ 0 Ma BP）.
