| 摘 要： | 天然热释光测量方法是近几年发展起来的寻找隐伏铀矿体的方法。同时也是一种新的地质研究手段。经多种类型铀矿床的试验结果表明,该方法能有效地发现埋深几十米至二百多米深的盲矿体。此外,还可划分复式岩体不同侵入期和确定其侵入时代;区分产铀岩体与非产铀岩体;划分硅化带中各期石英岩的先后活动序次,进而确定与矿化有关的断裂带及各种热液铀矿脉的成矿时代。

| Abstract: | The method of natural thermoluminescence used to search for blind uranium ore bodies has been developed in recent years, and is a new means in geological research as well. From the experimental use in various types of uranium deposits, the results showed that this method is effective in finding blind ore bodies ranging from tens of meters to more than two hundred metrs deep. The other uses in geological aspects include the classification of the different intrusive stages of the compound rock bodies and the determination of their intrusive ages; the distinction betwee uraniumoccurring rock bodies and non-uranium-occurring rock bodies; the division of the activity sequences of quartzite in different stages in silicified zones, so as to ascertain the fault zones connected with mineralization and the minerogenetic epoch of varions hydrothermal veins. |
