摘要
塔里木盆地自前震旦—石炭纪经历了多期次的构造演化，前震旦纪盆地基底固结，震旦—奥陶纪为克拉通内坳陷、坳拉槽、被动大陆边缘；志留—泥盆纪为克拉通边缘隆升及石炭纪的克拉通内幼陷阶段。每次构造演化都与其周边的构造活动事件密切相关，从而控制了塔里木陆块内的沉积盆地样式及盆地属性的演化。本文讨论了塔里木盆地前震旦—石炭纪构造演化的阶段性，以及石炭纪原型盆地的属性，指出构造迁移现象是塔里木盆地构造演化的一个重要特征。
Talimu Basin has experienced polyperiod tectonic evolution from pre -Sinian to Car-bonifeous.Four stages are divided:(1)basement consolidation during pre-Sinian;(2)intracraton depression;aulacogen and passive continental margin from Sinian to Ordovician;(3)margin rise of the craton from Silurian to Devonian;(4)Intracraton depression during Carbonifeous.Each tec-tonic evolution stage within Talimu Basin results from tectonized events around Talimu Basin,and each tectonic movement controls the style of sedimentary basin and the changes of basin properties in Talimu craton. This paper discuss,es the stages of tectonic evolution from pre-Sinian to Car-bonifeous and the properties of primary basin during Carbonifeous.Furthermore,it shows that tec-tonic migration is an important character of the tectonic evolution of Talimu Basin.
