甘肃敦煌－北山地区广泛出露早前寒武纪岩石。这些岩石在早期的《甘肃省区域地质志》中被确定为前长城系、长城系、奥陶－志留系及部分石炭系。本文认为这些岩石应属太古宙和古元古代。据此，重新厘定了该区早前寒式纪岩石－构造框架。自南向北划分为敦煌太古宙杂岩区、北山南带古元古代剪切构造区和北山北带古元古代－太古宙杂岩区，并根据变形特点和岩石组合，进一步划分出次级带。
Gansu Dunhuang - Beishan area widely exposed early Precambrian rocks. These rocks were identified as the former Great Wall, Great Wall, Ordovician-Silurian and some Carboniferous in the early Gansu Province Regional Geology. This paper argues that these rocks belong to Archean and Paleoproterozoic. Based on this, we re-determined the Early Precambrian rock-tectonic framework in this area. It is divided into Dunhuang Archean Complex, South Paleoproterozoic shear structure zone and North Paleoproterozoic-Archean complex from south to north. According to the deformation characteristics and rock assemblage, sub-level band.
