| 中文摘要:斑岩铜矿床的铜金属储量占世界的一半以上,是全球最具经济意义的矿床类型。中国大陆具有独特的地质演化历史,显生宙以来一系列构造-岩浆活动,促成了富水岩浆的浅成、超浅成侵位,为斑岩铜矿床的形成创造了有利的环境。文章立足于中国大陆的成矿地质背景,对中国大陆的斑岩铜矿床的时空分布再次进行了梳理和分析,在三大古板块边界控制成矿域的基本体制下,进一步强调次级"微板块"构造与斑岩铜矿床的成因联系,提出了"3大成矿域、7大成矿区"的区划方案,并以特提斯成矿域"陆缘增生-陆内深熔作用"为重点,探讨了具有中国大陆特色的板内成矿作用。 |

| Abstract:As a kind of ore deposits with most important economic significance, the porphyry copper deposits possess more than half of the global copper reserves. China's mainland has its unique geological evolution history. A series of tectonic-magmatic activities promoted the hypabyssal -ultrahypabyssal invasion of magma with rich water, which created the favorable environment for the forming of porphyry copper deposits. Based on the metallogenic geological background of China's mainland, this paper systematically analyzes temporal and spatial distribution of porphyry copper deposits, highlights the genetic connection between secondary "micro plate" tectonics and porphyry copper deposits under the basic system of three metallogenic domains controlled by paleo-plate bounda-ries, puts forward the regionalization system of "three metallogenic domains, seven metallogenic regions", and studies the intraplate mineralization with characteristics of China's mainland by placing emphasis on "continental margin accretion-inner continent anatexis". |
