| 摘 要： | 围山城金银多金属成矿带处于秦岭造山带东段核部,其由多个形成于不同构造环境,有着各自独立的建造特征、变形变质和构造演化序列的构造地层地体,经多次聚合后拼贴并焊结为一体的复杂构造带。研究该矿带成矿作用和在不同时代岩浆岩、主要脉岩、围岩蚀变、微量元素及地球化学特征,了解元素富集变化规律,建立了地质-地球化学找矿标志。

| Abstract: | Lying at the core part of Qinling orogenic belt, the Weishancheng Au-Ag polymetallic ore belt is a complex tectonic belt produced by repeated convergence, piecing together and welding of several strata and terrains which were formed in different tectonic settings and had their respective formation characteristics as well as independent deformation, metamorphic and tectonic evolutionary sequences. This paper has studied the ore-forming process of this ore belt and magmatic rocks, major vein rocks, wall rock alterations, trace elements and geochemical characteristics of various epochs, probed into the regularity of element enrichment and variation, and established geological-geochemical ore-prospecting criteria. |
