摘　　要：在《准噶尔盆地哈拉阿拉特山冲断带构造及找油意义》一文中,用于支持其构造模式成立的和什托洛盖盆地的三叠系和二叠系具有很大的推测成分,与实际地质资料差别大。此外,文中提出的"哈拉阿拉特山冲断带的活动时间起始于三叠纪末,并在侏罗纪末发生继承性活动,白垩纪之后,冲断活动已经基本停止",笔者认为,至少可以说,该冲断带模式中的下构造层最强烈的变形时间应当主要是发生在新生代以来,新构造运动强烈改造了历次前期的构造活动证据,造成前期构造恢复工作的难度。In literature [1] Thrust Belt Structure and Significance for Petroleum Exploration in Hala＇alat Mountain in Northwestern Margin of Junggar Basin, the Triassic and Permian strata in Heshituologai basin, which were used for supporting its proposed tectonic patterns, are in big differences compared with the actual geologic data. Also, it was concluded by above paper that the deformation of Hala＇alat thrust belt originated from the Late Triassic, inherited at the Late Jurassic and ceased after the Cretaceous. The authors in this paper argue that the most intensive deformation of lower structural zone in that pattern should originate mainly from the Cenozoic, and it is the neotectonic movement that transforms intensively all previous tectonic movement evidences, resulting in the difficulties for recovery of previous tectonic/structural deformation in this area.
