摘要
作者根据重力、磁力、地震、钻井及区域地质等地质地球物理资料对准噶尔盆地的基底性质、形成及演化作了探讨,认为准噶尔盆地基底主要由玛纳斯地体和乌伦古地体在石炭纪末期拼贴而成,拼贴交接带在三个泉隆起轴部。自晚古生代至第四纪,准噶尔盆地经历了分离的台地型海相盆地,前陆型海相盆地,裂陷型残留海相盆地,坳陷型陆相盆地,振荡型陆相盆地和收缩型陆相盆地等6个构造—沉积演化阶段。
The author made a discussion to the basement characteristics, formation and evolution of the Junggar Basin, ac-cording to some geophysical data such as the gravity, magnetic, seismic, well drilling and regional geology, and re-garded that basement of Junggar Basin is mainly formed by connection of Manas Terrene and Ulungur Terrene in lateCarboniferous those located in the axis of Sangequan uplift. In Palaeozoic to Quaternary, Junggar Basin was under-going six separated structural-depositional evolution stages, i. e, platformal marine basin,foreland marine basin,taphrogeny-remained marine basin, continent depressional basin, continent vibration basin, and continent contractionbasin.
