環(huán)太平洋成礦域主要銅-金礦床地質(zhì)特征、成礦作用及找礦潛力
發(fā)布時(shí)間:2018-08-14 18:04
【摘要】:環(huán)太平洋成礦域是全球最重要的成礦域之一,一直是世界找礦勘查開(kāi)發(fā)和成礦理論研究的熱點(diǎn)地區(qū)。域內(nèi)斑巖型、矽卡巖型、淺成低溫?zé)嵋盒、造山型、卡林型等大?超大型礦床在特殊構(gòu)造背景中密集分布,資源潛力巨大。這些礦床的成礦時(shí)代以中、新生代為主,構(gòu)造背景多為顯生宙造山帶,成礦作用多與太平洋內(nèi)各大洋板塊俯沖作用密切相關(guān),礦床的形成和產(chǎn)出具有明顯的偏在性、專(zhuān)屬性。介紹了環(huán)太平洋成礦域的成礦環(huán)境,選取代表性的銅和金礦床,歸納總結(jié)了其地質(zhì)特征和成礦作用,梳理討論了不同類(lèi)型礦床的成礦背景、分布規(guī)律,分析了區(qū)域找礦潛力。
[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.
