Abstract

Abstract: The original thickness of salt layers and some geological constraints of growth strata of Kuqa Depression in the northern Tarim Basin were predicted.The plastic flow of salt bodies and the kinematic characteristics of salt structures were analyzed by using the balanced section technology.The analysis results indicate that the original thickness of Paleogene Kumugeliemu Formation in Kuqa Depression is about 1130 meters,and the intense structural distortion of salt structures occurred in the later Himalayan period from the Kuqa period to the Quaternary.The balanced sections of salt structures in Kuqa Depression show that the shortened distance along northwest to southeast is 18~31 kilometers,and the shortening rate is from 16% to 34%.In addition,the kinematic characteristics of varying structural belts,sectors and layers in Kuqa Depression are obvious different.The salt layers acted as important detachment and harmonizer in the differential structural distortion.

Key words: Kuqa Depression, salt structure, kinematic characteristics, balanced section technology, differential structural distortion

摘要： 预测了塔里木盆地库车坳陷盐层初始沉积状态,分析了盐体塑性流动过程,并结合生长地层等地质约束条件,应用平衡剖面技术,分析了该地区盐构造的运动学特征。分析结果表明,库车地区库姆格列木组膏盐层初始沉积厚度约为1130m,盐构造强烈变形主要发生在库车期—第四纪(距今1.64Ma以来)的喜马拉雅运动晚期;库车坳陷NW—SE向缩短量约为18~31km,缩短率为16%~34%;库车坳陷构造变形具有分层缩短、分带缩短、分段缩短的特点,盐层在这种差异构造变形过程中起到了重要的滑脱、调节作用。
