摘　　要：基于对断面域前寒武纪基底、古生代碎屑岩和花岗质岩石的化学组成分析，结合区域成矿和构造演化特征，建立了断面域前寒武纪和古生代两个不同时间域的地球化学分区。通过地球化学分区与构造演化的关系研究，探讨了地球化学区形成的构造过程。Based on the chemical analyses of Precambrian and Paleozoic clastic rocks and granitic rocks, in conjunction with the characteristics of regional mineralization and tectonic evolution, the geochemical division patterns have been established for the two areas of Precambrian and Paleozoic ages. According to the relationship between the geochemical division and the tectonic evolution, the tectonic process during the formation of geochemical regions is discussed.
