| 摘 要： | 塔里木盆地深层次推覆-滑脱构造表现为前震旦系基底岩系中的韧性剪切带;中层次表现为古生界逆冲推覆、滑脱褶皱和牵引背斜;浅层次以中—新生界褶皱-冲断层带为特征。塔里木盆地大型隆起带的形成与中、深层次推覆-滑脱作用有关,它们是寻找大型油气田的主要油气聚集带。山前坳陷中发育浅层次推覆-滑脱构造,是寻找中、小型油气田的有利构造带。

| Abstract: | The main features of nappe-detachment structures in Tarim Basin are thrusting, compressional folding and shortening. The deep-level nappe-detachment structures of pre-Sinian are in form of ductile shear belt. The mid-level structures of Paleozoic contain nappes, decollement folds and drag anticlines. The shallow-level structures of Meso-Cenozoic are characterized by fold-thrust belt.
The formation of North, Central and South Uplift has a bearing upon mid-level nappe-detachment . These uplifts are major hydrocarbon accumulation belts in search of huge oil-gas fields. Shallow-level nappe-detachment structures mainly occur in Kuqa, Southwest and Southeast Depression which are favourable belts for searching oil-gas fields of middle-small size. |
