本文根据苏联某铀矿区获得的资料,详细阐述了利用地球化学找矿方法寻找热液铀矿床肓矿体的理论基础和工作方法。这分材料比较系统、具体,可供读者参考。但是,在将这分资料介绍给读者的同时,我们认为有必要强调,在应用地球化学找矿方法时,必须注意:(1)首先应对该矿区已知矿体的地质构造特点和矿石物质成分特点进行一定的了解和研究;(2)在每个地区都必须坚持事先进行方法试验,找出在该区利用此方法的具体条件(如地球化学底数值、伴生元素、指示元素、已知矿体的扩散晕发育情况等);(3)地球化学找矿方法必须与共他找矿方法(首先是地质-物探方法)配合,作为综合找矿的一部分,而绝不能孤立进行。只有这样,才能合理利用这一找矿方法,充分发挥它的作用,否剐难以取得应有成效。
Based on the data obtained from a uranium mining area in the Soviet Union, this paper elaborates on the theoretical basis and working methods of using geochemical prospecting methods to find the ore body of hydrothermal uranium deposits. This sub-material more systematic, specific, for readers reference. However, while introducing this material to our readers, we think it is necessary to emphasize that we must pay attention to the following aspects when applying geochemical prospecting methods: (1) Firstly, we should deal with the geological structure and ore composition (2) In each region, the methodological test must be carried out in advance to find the specific conditions for using this method in the region (such as the geochemical bottom value, associated elements, indicator elements, known ore Etc.); (3) The geochemical prospecting method must be used in conjunction with the prospecting method (first of all, the geology-geophysical prospecting method) as part of comprehensive prospecting and must not be carried out in isolation. Only in this way can we make rational use of this prospecting method and give full play to its role, failing to achieve the desired results.
