摘要
钨矿是我国的优势矿产资源,储量、产量、消费量和出口量均居世界首位,尤其自本世纪以来,我国钨的年产量稳居全球80%以上。钨在现代工业和生活中有广泛的应用,是一种重要的战略资源。对近20年来,钨的地球化学研究进展进行了概括性综述,包括钨在太阳系、行星地球及其各种主要内生、表生产物中的分布,钨在岩浆-热液过程和表生作用中的地球化学行为,以及钨的生物效应和环境影响等。值得指出的是,近十年来,最值得关注的是有关钨的生物效应和环境影响方面的研究进展。我国作为世界产钨大国,对钨在生物地球化学和环境化学及其健康影响方面的研究几乎还是空白,亟需尽快开展这方面的数据积累和研究。
China＇s tungsten reserves, production, consumption and volume of export all rank first in the world. China has been producing more than 80% of the total production in the world since 2000, and has preponderant influence in the nonferrous metal market of the world. Tungsten as an important strategic resource has found a wide utilization in modem life, industry, oil exploration, military equipments etc. The present paper reviews the progress in research on geochemistry of tungsten in last 20 years, including tungsten distributions in the solar system, in the earth and in the principal units and products from both endogenesis and supergenesis. The geochemical behavior of tungsten in magmas, hydrothermal fluids, supergenesis, and related effects on bionts, environment and health are also discussed. It is pointed out that the study on geochemistry of tungsten in its effects on environment and health is almost a research gap in our country now. Special attention should be paid to this aspect of research.
