本文通过对塔里木盆地航磁资料的综合解释,探讨了该区深部基底构造及区域构造特征。指出在盆地深部存在一个较古老的结晶地块,它对盆地的形成及发展起着明显的控制作用。通过对重、磁及地震测量资料的分析,探讨了该区古生界、中生界及新生界等构造层发育的一般概况;并将盆地内划分为中央隆起带、西南拗陷带、塔东拗陷区、塔北隆起区、库车山前拗陷及塔东南断阶构造带等单元;指出了该区断裂发育及华力西期基性岩的分布情况。最后对西南拗陷带及塔东拗陷区的油气远景作了初步评价。
Based on the comprehensive interpretation of aeromagnetic data in the Tarim Basin, this paper discusses the deep basement structure and regional tectonic features in this area. It is pointed out that there is an ancient crystalline block in the deep basin, which plays a significant role in controlling the formation and development of the basin. Through the analysis of heavy, magnetic and seismic data, the general survey of the tectonic development in the Paleozoic, Mesozoic and Cenozoic is discussed. The basin is divided into central uplift, southwest depression, tower Eastern depression area, northern Tabeng Uplift, Kuqa piedmont depression and east southeast fault structure tectonic belt; pointed out the fault development and the distribution of the Variscan basic rocks. Finally, the oil and gas vistas in the southwestern depression zone and the Tadong depression area are initially evaluated.
