摘要
绿泥石化是铀矿床的一种重要近矿蚀变,其成分类型、成因的研究因受其颗粒细小的影响受到很大的限制。本文采用矿石中提取的绿泥石作x衍射鉴定,然后再用绿泥石的X衍射特征峰值求出富镁的斜绿泥石,同时还根据其氢氧稳定同位素结果判断绿泥石为大气降水与岩石热交换的产物。
Chloritization is an important wallrock alteration near the ore body. The study of chloritic compositional types and origins has been greatly limitted owing to its very fine shape. This paper uses the chlorite separated from the ore to identify X-ray diffraction, and then uses the peak value of chlorite X-ray characteristics to work out the grastite of magnesium. At the same time, the paper judges chlorite as the product of atmospheric water and rock exchange of heat in terms of its results of stable isotopes of hydrogen and oxygen.
