诸广山岩体南部钍、钼物化探场与铀成矿关系初探

在铀成矿富集过程中，主元素和伴生元素可形成呈指数衰减的物化探晕。利用放射性仪器对原生晕进行测量，把实测数据按一定的场级圈定物化探场，并结合地质情况分析研究，可推测地下铀矿体的含量、形态、规模等特征。选择了诸广山岩体南部的钍和钼元素为研究对象，探讨其与铀成矿关系。结果表明，钍、钼元素以及其他元素引起的物化探晕与铀成矿存在一定的关系，可以为铀矿找矿提供依据。通过对主元素和伴生元素原生晕的研究，利用多种物化探方法综合测量、分析，剔除分散性矿化等影响因素，进而在实际工作中能以更准确、更有效的物化探信息去指导铀矿深部探索。

Initial Discussion about the Relationships of Uranium Mineralization and Thorium,Molybdenum in the South of Zhuguang Granites

The main elements and associated elements can generate the geophysical and geochemical halos which is exponential decay in the enrichment process of uranium ore. The datas that are measured by radioactive apparatus which delineating geophysical and geochemical halos according to a certain grade, it＇s possible to estimate the content, shape, size of hidden ore bodies by researching geological conditions. Choosing thorium and molybdenum as the research objects to discuss their relationships with uranium mineralization. The results express that there are certain relationships amomg uranium mineralization and thorium, molybdenum as well as other elements, they can provide basises for exploring uranium mineralization. Geophysical and geochemical informations are more accurate and effective to find hidden uranium ores in actual work by researching primary halos of the main elements and associated elements, making use of a variety of geophysical and geochemical approaches to measure, analyse, excluding factors of dispersed uranium ores and so on.
