柴达木盆地西北缘阿尔金山前的一系列弧形条带,早已引起人们的注意。笔者通过在盆地的工作,在前人研究的基础上[1][2],进一步提出和探讨盆地中的阿尔金弧形构造带。认为它们是在印度板块或洋壳的水平挤压下,受阿尔金深断裂剪切牵引而形成的中新生代弧形构造带,是基岩断裂带控制下的构造复合带,也是有利的油气富集带和多种油藏类型
A series of arcuate bands in front of the Altun Mountains on the northwestern margin of the Qaidam Basin have drawn people’s attention. Through the work in the basin and on the basis of previous studies [1] and [2], the author further proposes and discusses Argun arc structural zones in the basin. They are considered as Mesozoic-Cenozoic arcuate tectonic belts formed by horizontal shear deformation of the Indian plate or oceanic crust under the shear of Altyn Deep Fault. They are structural composite belts under the control of bedrock fault zones and are also favorable oil and gas Enriched belts and a variety of reservoir types
