摘要: 根据对西汉水群的详细解体、划分，首次在西和—成县地区发现元古代地层单元。在多尺度、多层次构造解析的基础上，建立了该区自古生代以来的构造演化序列。
Abstract: According to the latest data of 1∶50 000 regional surveys in the Xihe Chengxian area, the Xihanshui system is disintegrated. The Middle Upper Proterozoic Haijiushan Formation and Upper Silurian Shuangliuzhou Formation have been newly established. On the basis of a detailed structural analysis, a succession of tectonic evolution since the Paleozoic has been set up .
