摘要
在野外地质调查基础上,对准噶尔盆地南缘构造特征进行了系统论述,结合准噶尔盆地南缘部分地震与钻井资料揭示的深部构造情况,将准噶尔盆地南缘构造单元划分为冲断推覆系统和原置变形系统两大类,其分界面应为霍玛吐前锋断裂,此断裂在深部资料上显示为向南倾斜的台阶状逆断层。
The structural feature of the southern fringe of Junggar Basin is described systematically on the basis of geological survey in this paper. Combined with the condition of deep structure indicated by seismic and drilling data of the southern fringe of Junggar Basin, the authors can divide the southern fringe of Junggar Basin fracture zone into obduction-nappe system and homeland deformation system. The line of geological limitation of them should be the Huomatu fault front which is shown as the south-dip step fault in the seismic profile.
