摘要
提出“序列-阶段”期次分析方法;讨论了矿床的热液演变过程,铀的富集因素及成矿物质之来源;对矿床成矿温度,压力和成矿介质的pH.Eh及组分等进行了研究,从而提出“双溶液混合”成矿的成因观点。
Presented in this paper is an approach to the analysis of 'sequence-stage' division. The processes of hydrothermal evolution involved in ore deposition, the factors affecting the enrichment of uranium and the source of ore-forming elements in uranium deposit No. 720 are also discussed. In addition, the ore-forming temperature and pressure as well as the pH, Eh and chemical composition of ore-forming medium are studied with reference to the fluid inclusion data available. A double-solution mixing model has been proposed to explain the metallogenic origin of the uranium deposit studied.
