南祁连哈拉湖——青海湖一带,于二迭——三迭系地层中发育数条北北东向展布的构造形迹,与区域性北西——北西西向构造线很不协调,尤以阳康地区最为醒目。北北东向构造是阳康地区长期活动的构造,它们形成于加里东时期,结构面多为张性,并控制了本区华力西——印支期的建造和形变过程。本文通过阳康地区构造形迹的剖析,试 In the area along the Hala Lake-Qinghai Lake in the Southern Qilian, several tectonic traces of the NE-EAST distribution are developed in the Permian-Triassic strata, which are not in harmony with the NW-NWW tectonic line To Yangkang most eye-catching. North-EAST tectonics is a long-term active structure in the Yangkang area. They formed during the Caledonian period and were mostly extensional and dominated the construction and deformation processes of the Variscan-Indosinian. This article through the analysis of the structure of Yangkang region, try
