摘要
我国天青石矿产资源比较丰富,成矿条件良好。经多年的普查勘探和综合评价,已经积累了一定的矿床地质资料和研究成果。本文即在前人工作的基础上,通过分析锶的地球化学和成矿机理,对我国天青石(包括菱锶矿)矿床的成因类型进行了初步划分,并根据各类型的特点,指出了我国天青石矿床的找矿方向。本文撰写过程中,得到成都地质矿产研究所许效松、王吉礼同志和地质矿产部钱大都、任希文同志的大力支持,在此表示感谢!
This paper mainly analyses the geochemical characteristics and mechanisms of concentration and dispersal of strontium in various metallogenic processes such as magmatism,pegmatitization,hydrothermal processes,hot brine deposition,sedimentation and supergene enrichment,and,on that basis,divides celestite deposits of China into eight types of five categories.According to the associations of country rocks,the sedimentary category is subdivided into the type of marine clay-carbonate sedimentary association,the type of marine sulfate sedimentary association and the type of continental sulfate sedimentary association.The stratabound category includes the sedimenary hot brine or hydrothermal type.The volcanogenic category includes the volcanic fluid type.The hot brine or hydrothermal category is subdivided into the type of celestitecarbonate association and the type of sulfidecelestite association.The supergene category includes weathering-leaching type.Moreover,on the basis of a preliminar summing-up of the geological charateristics,laws of distribution and metallogenic ages of different types of deposit,this paper points out the direction in search for celestite deposits in China.
