摘要
α径迹蚀刻方法应用于铀矿研究,可简便有效地研究岩石、矿石中铀的分布状况、存在形式,研究与铀矿化相关的蚀变作用等,根据矿石的α径迹特点得出铀以分散吸附状态、铀矿物、类质同像3种形式存在。本文以相山热液型铀矿石为例,介绍了采用α径迹蚀刻方法研究热液型铀矿石中铀的赋存状态,铀的富集规律,根据矿石的α径迹特征得出热液型铀矿石中的铀主要以吸附状态和铀矿物2种形式存在,铀矿化与黄铁矿化有密切的关系。
Alpha particle track etching method applied to uranium research, can be simple and effective to study the distribution status and existence form of uranium in the rock and ores, and alteration associated with uranium mineralization, and so on, based on alpha particle track features concluded that uranium adsorption in three different form, such as decentralized state, uranium minerals and isomorphism. The Xiangshan hydrothermal uranium ore as an example, the occurrence and enrichment regularity of uranium in hydrothermal uranium ore by alpha particle track etching method were introduced in this paper, the results showed that uranium mainly adsorption in adsorption state and uranium mineral two forms, uranium mineralization and pyritization were closely related.
