论中国钙芒硝矿床

钙芒硝矿床与芒硝矿床一样都是提取化工原料———硫酸钠的重要非金属矿产。中国钙芒硝矿产储量丰富 ,已被开发利用 ,更是潜在的具有重要经济价值的矿床。按其成因可划分为第四纪盐湖型、中新生代陆相碎屑岩型及古代海相碳酸盐型三大类。对钙芒硝矿物精心研究表明 ,钙芒硝的成因与生物作用关系极为密切 ,钙芒硝矿床当属生物化学成因。通过对中国钙芒硝矿床的深入研究 ,得出认识是 :该类矿床具有分布广、成矿延续时代长、矿床成因类型多的特点。中国西部地区钙芒硝矿床发育次生富集带 ,形成可供工业利用的次生芒硝矿床。

ON GLAUBERITE DEPOSITS IN CHINA

Like mirabilite deposits, glauberite deposits are important nonmetallic ore resources used for extracting from them a chemical raw material, sodium sulfate. They have rich reserves in China, which have been tapped and utilized, of a great potential economic value. Genetically, they may be classified as three primary types, Quaternary saltlake type, Mesocenozoic continental cataclasite type and old marine carbonate type. Mineralogic studies reveal that they formed, to a great degree, with aid of organism and hence are believed to be of biogenesis. Further probe also indicates that they are characteristic of wide distribution, long mineralization and various genetic types. There is a secondary enrichment zone of glauberite in the western part of China to have developed a number of usable glauberite deposits.
