一、前言青藏高原北部拥有我省二条著名的雄伟山系——东昆仑山与祁连山。这两条山系与其间的柴达木盆地北缘前寒武系比较发育,构成本区早期大地构造格架,对早古生代以来构造发展、地层沉积型相变化起有重要控制作用。本文依据我省前寒武系资料及我所震旦系专题组资料,对前寒武系沉积特征与地质构造有关问题作一扼要总结,错误之处,请批评指正。 I. Preface The northern part of the Qinghai-Tibet Plateau owns two famous majestic mountains in the province - the East Kunlun Mountains and the Qilian Mountains. These two mountain systems and the Precambrian in the northern margin of the Qaidam Basin are well developed and constitute the early tectonic framework of the area, which plays an important role in controlling the tectonic development and stratigraphic sedimentary facies changes since the Early Paleozoic. Based on the Precambrian data of our province and the data of the Sinian Specialist Group in our province, this article briefly summarizes the sedimentary characteristics and geological structure of the Precambrian facies and puts forward some criticisms and corrections.
