中国铜矿床成矿系列研究进展

Study advancement on minerogenetic series of copper deposits in China

矿床成矿系列理论在中国经过三十多年的发展,已被广泛应用于找矿勘查实践。文章在以往矿床成矿系列研究的基础上,对中国铜矿床的成矿系列进行了补充与完善,厘定出30个以铜为特色的矿床成矿系列。结合全国地质与成矿演化,分析铜矿床成矿系列在主要地质历史时期的特点与时空分布规律,其中,前寒武纪7个铜矿床成矿系列,矿床类型以变质型和岩浆型为主;古生代8个铜矿床成矿系列,矿床类型以海相火山岩型为主;中生代13个铜矿床成矿系列和新生代2个铜矿床成矿系列,矿床类型均以斑岩型和矽卡岩型为主。西藏地区铜矿找矿突破显著,新增2个全国范围的铜矿床成矿系列。矿床成矿系列的复合,是中国铜矿床成矿系列研究的重要成果和特色。

The theory of minerogenetic series of ore deposits in China has been widely accepted and used by Chinese geologists for mineral exploration after its thirty-years development. Based on the previous study on mineroge- netic series of ore deposit, authors supplemented the minerogenetic series of copper deposits in China. There are 30 minerogenetic series of copper deposits determined. Combined with the evolution of geology and mineraliza- tion in China, the characteristics and the temporal and spatial distribution of minerogenetic series of copper de- posits are analyzed in the main geological history. There are 7 minerogenetic series of copper deposits in PreCam- brian with major sedimentary metamorphic type and magmatic rock type copper deposits. There are 8 mineroge- netic series of copper deposits in Paleozoic with major marine volcanic rock type copper deposits. There are 13 and 2 minerogenetic series of copper deposits in Mesozoic and Cenozoic with major porphyry type and skarn type copper deposits. Copper deposits in Tibet region have been explored significantly in recent years, and there are 2 metallogenic series of copper deposits created. The composite of the ore deposit minerogenetic series is an impor- tant achievement and a feature of metailogenic series of copper deposits in China.
