摘要
黏土矿化是层间氧化带砂岩型铀矿床普遍发育的蚀变作用,黏土矿物在铀成矿过程中作用一直是该类铀矿床研究的重要内容之一。本文通过野外岩心观察、岩矿鉴定镜下分析及扫描电镜和能谱分析对研究区含矿目的层赛汉组中黏土矿物特征进行研究分析。发现目的层赛汉组中发生了明显的黏土矿化作用,研究认为黏土矿物吸附作用是形成铀矿化的主要因素之一。
Clay mineralization is a generalized alteration of interlayer oxidized sandstone-type uranium deposits. The role ofclay minerals in uranium mineralization has always been one of the important contents of this type of uranium depositresearch. In this paper the characteristics of clay minerals in the Saihan Formation of the ore-bearing target layer in the studyarea were studied and analyzed by field core observation microscopic analysis of rock and mineral identification, andscanning electron microscopy and energy spectrum analysis. The author found that there is obvious clay mineralization in theSaihan Formation of the target layer. It is believed that the adsorption of clay minerals is one of the main factors for theformation of uranium mineralization.
