| 摘 要： | 区域成矿作用的地球化学研究必须以岩石圈物质分异的观点来认识地壳地元素迁移和演化，必须以大区域地壳体系的地球化学特征来指导局部地区的基础地质认训和找矿问题，这是由于地壳与地幔体系的物质运动是不平衡的，明显具分异特征，为些不同构造单元岩石圈的化学成分是不均一的，这就决定了不同构造单元的成岩，成矿作用具有不同的地球化学特征，本文从东秦岭及领区岩石圈金的丰度特征研究入手，探讨该区不同构造环境中金（银）成太

| Abstract: | In the geochemical study of the regional minerali2ation, the viewpoint and theory of the material differentiation in the lithosphere were used to illustrate the migration and evolution of the elements in the crust. The local geology and the mineral exploration must be considered the geochemical characteristic of the large regional crust system. because of th?unblance the material movement exisiting between the crust system and the mantie system. They are characterized by distinct differentiation. Therefore, the unhomogeneity of the chemical composition of the lithosphere in various tectonic -units can result in the differently geochemical characteristics of the rock - forming and mineralization. The research begins with the gold abun-dance of the lithosphere in Eastern Qinling and its adjacent areas. The styles of Au(Ag) mineralization in various tectonic settings are discussed, and the geochemical indicators for exploring the various Au(Ag) deposits are provided. |
