摘　　要：古生代是中国大陆重要的成矿期之一,在空间分布上,磷、锰、铝、煤、重晶石、金刚石等矿产主要分布在华北、扬子等稳定地台区,稀土、大理岩、硅灰石、云母、水晶、萤石、铜钼、锂铍、金等矿产主要分布在天山—兴蒙造山系,铅锌矿分布在秦岭弧盆系和武夷—云开造山系。油气主要分布在塔里木、华北陆块沉积盆地内,页岩气主要分布于扬子陆块沉积盆地内。整个古生代以沉积作用成矿为主,晚古生代岩浆成矿作用有所增强。在全面搜集、综合研究以往资料的基础上,本文以板块构造与地幔柱理论为指导,以活动论的观点,划分古生代地质构造单元,讨论了中国古生代主要成矿作用类型,进一步完善了中国大陆古生代成矿规律。The Paleozoic is one of the important mineralization periods in China's Mainland.In terms of spatial distribution,minerals such as phosphorus,manganese,aluminum,coal,barite and diamond are mainly distributed in stable platform areas such as North China and the Yangtze,while rare earth,marble,wollastonite,mica,crystal,fluorite,copper,molybdenum,lithium beryllium and gold are mainly distributed in Tianshan-Xingmeng orogenic system.The lead-zinc minerals are distributed in the Qinling arc basin system and the Wuyi-Yunkai orogenic system.Oil and gas are mainly distributed in Tarim and North China continental Block sedimentary basins,and shale gas is mainly distributed in the Yangtze continental Block sedimentary basin.The entire Paleozoic was dominated by sedimentary mineralization,and magmatic mineralization increased in the late Paleozoic.Based on the comprehensive collection and study of previous data,guided by the theory of plate tectonics and mantle plumes,and from the perspective of activity theory,the Paleozoic geological structural units were divided,the main types of mineralization in the Paleozoic in China were discussed,and the Paleozoic in China's Mainland was further improved mineralization rules.
