摘要: 塔里木盆地北部地区在海西晚期塔里木板块北缘和南天山造山过程中发生的斜向碰担和逆冲一走滑作用的影响下, 形成了既有逆冲推覆又有走滑扭动的构造变形。这种构造变形形成了不整合、断块、背斜、古潜山、风化壳等多种类型的圈闭, 为塔里木北部地区的油气藏(田)的形成创造了有利条件。

Abstract: Deformation structures including thrust nappe and strike slip shear formed in north area of Tarim basin in late of Hercynian orogeny being influenced by oblique collision of north margin of Tarim plate with south Tianshan mountain during orogeny and thrust-strike slip action, which produced many types of traps including unconformity, fault blocks anticline, buried hill and weathering crust. These traps are favorable for the formation of reservoir (oilfield) in north area of Tarim basin.

Key words: Tarim basin, Hercynian orogeny, Nappe, Strike-slip fault, Oil and gas reservoir
