环太平洋成矿域主要铜-金矿床地质特征、成矿作用及找矿潜力
发布时间：2018-08-14 18:04
【摘要】：环太平洋成矿域是全球最重要的成矿域之一,一直是世界找矿勘查开发和成矿理论研究的热点地区。域内斑岩型、矽卡岩型、浅成低温热液型、造山型、卡林型等大型-超大型矿床在特殊构造背景中密集分布,资源潜力巨大。这些矿床的成矿时代以中、新生代为主,构造背景多为显生宙造山带,成矿作用多与太平洋内各大洋板块俯冲作用密切相关,矿床的形成和产出具有明显的偏在性、专属性。介绍了环太平洋成矿域的成矿环境,选取代表性的铜和金矿床,归纳总结了其地质特征和成矿作用,梳理讨论了不同类型矿床的成矿背景、分布规律,分析了区域找矿潜力。
[Abstract]:The Pacific Rim metallogenic domain is one of the most important metallogenic regions in the world. The porphyry type, skarn type, epithermal hydrothermal type, orogenic type, Carlin type and other large and super-large deposits are densely distributed in the special tectonic setting and have great resource potential. The metallogenic epoch of these deposits is mainly Mesozoic and Cenozoic, and the tectonic setting is mostly Phanerozoic orogenic belt. The mineralization is closely related to the subduction of various oceanic plates in the Pacific Ocean, and the formation and occurrence of the deposits are obviously partial and exclusive. This paper introduces the metallogenic environment of the metallogenic region around the Pacific Ocean, selects the representative copper and gold deposits, summarizes their geological characteristics and mineralization processes, discusses the metallogenic background and distribution of different types of deposits, and analyzes the regional prospecting potential.
