摘要： 阿尔金构造带位于天山一昆仑山之间,宽约200km,延伸1500km以主,是一个以东西向构造为背景,以北东向构造为主导的断裂隆起构造带。前者控制着构造带的基底构造格架,后者控制着区域构造格架。北东向构造、东西向构造,以及它们的联合、复合构造,构成了阿尔金构造带的主要构造面貌。在阿尔金构造带内及其邻近地区发育着拉张型、扭动型、挤压型三种盆地。它们均具有一定的油气远景,其中以扭动型盆地最具有找油现实意义。

关键词: 阿尔金构造带, 东西向构造, 北东向构造, 盆地类型

Abstract: Altun tectonic belt lies between Mounts Tianshan and Kunlun, with about 200 km in width and extension of over 1500 km, which is a faulting and uplifting tectonic belt with EW-trending tectonic setting control in tectonic frame work of basement as NE-trending leading tectonics controlling regional tectonic framework. NE and EW tectonics, along with their conjunction and compounding, form the major tectonic forms of Altun tectonic belt. Three types of basins with certain degrees of prospectives (tensional, shear and compressional) are present within Altun tectonic belt and adjacent regions, amongst which the shear basin is the most promising target for oil.

Key words: Altun tectonic belt, EW-trending tectonics, NE-trending tectonics, Basin type
