在 1∶2 5万基础地质调查过程中 ,通过分析前人资料 ,结合野外调查及室内分析 ,对白银地区早古生代地层重新进行了详细划分 ,首次在寒武纪地层中发现早期脆性断裂及顺层韧性剪切叠加变形。在多尺度、多层次构造解析的基础上 ,建立了区内早古生代地层构造演化序列。
In the 1: 250,000 basic geological survey process, the paleozoic strata in Baiyin area were re-classified in detail by analyzing the ancillary data, field investigation and laboratory analysis. For the first time, early brittle fracture and cis Layer ductile shear superimposed deformation. Based on the multi-scale and multi-level structural analysis, the Early Paleozoic stratigraphic evolution sequence was established.
