摘要
北山地区构造单元归属历来为众多地质学家所关注。笔者结合区内的地质实际 ,拟定出一、二、三级构造单元划分和命名的一般原则 ;运用板块构造观点和多旋回开合构造理论 ,将本区共划分出 3个一级构造单元 ,8个二级构造单元和 2 6个三级构造单元 ;阐述了各构造单元主要地质特征。认为本区先后存在红柳河—牛圈子—洗肠井(早古生代 )和红石山—百合山—蓬勃山 (晚古生代 )两条缝合带 。
This paper gives some general principles about the division and naming of tectonic units of Beishan area According to the theory of plate tectonics and polycyclic opening closing tectonics, Beishan area is divided into three first order tectonic units, eight second order tectonic units and twenty six third order tectonic units There are two suture zones in Beishan area: the Hongliuhe Niujuanzi Xichangjing suture zone (Early Paleozoic era) and the Hongshishan Pengboshan suture zone (Upper Paleozoic era), and the latter is the final plate junction between the Tarim Plate and Kazakhstan Plate
