摘要： 非洲拥有丰富的油气资源,是世界油气勘探的热点地区之一,也是我国石油公司海外油气勘探的重要区块。阿尔及利亚北部阿特拉斯造山带构造特征复杂,构造演化规律不明确,成为其内部山间盆地油气勘探难点。以现代构造地质与地球动力学理论为指导,划分了研究区构造演化阶段:三叠纪–早侏罗世裂陷期、中侏罗世–白垩纪裂后沉降期、新生代反转隆升期3 个阶段。并指出了其动力学机制:中生代新特提斯洋、大西洋开启及冈瓦纳大陆解体,是阿特拉斯造山带裂陷沉降的动力学背景;新生代特提斯洋关闭、非洲与欧亚板块汇聚,是造成阿特拉斯造山带反转隆升的主要原因。

Abstract: Africa is rich in petroleum resources. It is one of the hotspots for oil-gas exploration in the world and major blocks of China's overseas investment for it. The Atlas orogen in northern Algeria is characterized by complex structures and unclear structural evolution regularity, which becomes the bottleneck for inside hydrocarbon prospecting in its intermountain basin. Based on the theories of modern structural geology and geodynamics, the structural evolution in this area can be divided into three stages such as Triassic-Early Jurassic rift stage, Middle Jurassic -Cretaceous subsidence stage and Cenozoic reverse-uplifting stage. It is pointed out that its dynamic mechanism is that the open of the Mesozoic Neo-Tethys and Atlantic oceans and the dismember of Gondwana land are the dynamic settings for rift and subsidence of Atlas orogen, while the close of the Cenozoic Tethys ocean and the convergence between Africa plate and Eurasian plate are the main reasons for the reverse-uplifting of Atlas orogen.

Key words: Algeria, Atlas orogen, structural evolution, dynamic mechanism
