【摘要】 根据钻井资料、地震资料及露头剖面资料,对塔里木盆地西南坳陷第三纪沉积物进行了沉积通量研究,编制了不同时期沉积通量的平面等值线图;结合沉积演化特征探讨了青藏高原隆升与研究区西南缘沉积物的响应,提出了青藏高原西北缘在中新世以前隆升缓慢,之后隆升幅度增大,上新世是快速隆升期,高原的形成过程不是以整体抬升为主,而是分块体阶段性抬升的结果。更多还原

【Abstract】 Based on drilling, seismic and outcrop data, a sedimentary flux study is conducted on Tertiary deposits in south-west depression of Tarim Basin, plane isograms of sedimentary flux at different periods are plotted. The uplift of Qinghai-Tibet plateau and the response of south-west marginal deposits in the studied area are discussed in combination with sedimentary evolution, it is proposed that Qinghai-Tibet plateau uplifts slowly at north-west margine before Miocene and then amplitude of uplift is boosted. Pliocene is the period of speeding up uplift, the process of Qinghai-Tibet plateau formation is not elevated integrately and elevated in blocks at each period.更多还原
