我国单一萤石矿床地质概要
GEOLOGICAL OUTLINE OF SINGLE FLUORITE ORE DEPOSIT IN CHINA
【摘要】 我国单一萤石矿床 ,成矿大地造单元主要为华南造山带和北山内蒙吉林造山系。酸性岩浆岩和碳酸盐岩及断裂构造与成矿关系密切。成因类型有热液充填型和热水沉积型两种 ,以前者为主 ,热液充填型矿床 ,矿体主要呈脉状、透镜状 ,以大中型矿床为主 ,成矿介质为大气降水 ,成矿温度为中低温 ,成矿时代为中生代 ;热水沉积型矿床 ,矿体呈层状 ,规模为大型 ,成矿时代为二叠纪。氟主要源于酸性岩浆岩 ,钙主要源于碳酸盐岩。可划分出 6个成矿区带 ,酸性岩浆岩、碳酸盐岩及断裂是主要控矿因素
【Abstract】 Minerogenetic geotectonic elements of single fluorite ore deposit in China are mainly southern China oro-genic belt and orogenic system of Beishan, Inner Mongolia and Jilin. Acid magmatic rock, carbonate rock and fracture structure close related with mineralization. The genetical type divided into hydrothermal filling type and hot water depositional type, and primary one in front. About hydrothermal filling ore deposit, the ore body mainly present vein and lens in shape, mainly as big to mid scale ore deposits, and minerogenetic medium was rainwater, and there were mid-lower minerogenetic temperature, it produced in Mesozoic Era. About hot water depositional ore deposit, the ore body present layer in shape, large scale ore deposit, and formed in permian period. Fluorine mainlystem from acid magmatic rock, calcium mainly stem from carbonate rock. It’s may be divided into 6 minerogenetic zones, and the acid magmatic rock, carbonate rock and fracture are main orc-controlled factors.
【Key words】 fluorite ore deposit; minerogenetic geological background; genetical type; minerogenetic zone; ore-controlled factor; China.;
