塔北沙雅隆起东段古生代断裂特征及演化
|
摘要
依据二维地震剖面的精细地质解释,将塔北沙雅隆起东段自加里东中-晚期以来的断裂活动细分为3期,并对其复合发育过程进行了探讨.研究表明:加里东中-晚期,区内主要发育近NW向的小型逆断层;海西早期,近EW向的压扭断裂开始大规模发育,部分近NW向的断裂也开始扭动,二者呈复合构造样式;海西晚期,区内断裂继承性活动,EW向断裂发生大规模逆冲活动,地层被大幅抬升,并遭受剥蚀.该项研究对于深化塔里木板块北部古生代构造变形研究以及油气勘探等都具有重要的意义.
Based on geological interpretation on seismic profiles,the characteristics and the evolution of the Paleozoic faults in Eastern Shaya Uplift are studied.The result shows that the Eastern Shaya Uplift mainly suffers from three tectonic movements in Paleozoic,which leads to the development of two sets of multi-tectonic activity faults that showe a compound structural style:the middle-late Caledonian movement leads to the small-scale development of the NW-trending thrust faults;in early Hercynian,the EW-trending lateral-slip faults began to move in large-scale.In the meanwhile,the pre-existing NW-trending thrust fault became reactive.Thus,a compound structure had been formed there;In late Hercynian,the pre-existing EW faults reactivated and thrust violently.As a result,the strata had been greatly uplifted and denuded intensely.It is very significant for this research to prompt the Paleozoic structural deformation and petroleum exploration in Northern Tarim Basin.
