A System of Geophysical and Geochemical Exploration Technology for Sandstone-type Uranium Deposits
为充分发挥物化探勘查技术在砂岩型铀矿勘查中的作用,本文通过梳理砂岩型铀矿勘查阶段及其地质目标任务,将铀矿勘查空白区开始找矿工作,到铀矿床落实与资源量估算的勘查过程,划分为战略选区、调查评价、普查、详查和勘探5个阶段.其中,调查评价阶段进一步细分为预测、查证和评价3个阶段,物化探勘查技术的作用也主要聚焦于该阶段.在此基础上,结合砂岩型铀矿勘查实践,总结物化探勘查技术的勘查作用与地质问题解决能力,构建砂岩型铀矿物化探勘查技术体系,同时提出不同勘查阶段的物化探勘查工作部署建议及应用示例.
To fully leverage the role and capabilities of geophysical and geochemical prospecting technologies in the exploration of sandstone-type uranium deposits,this paper proposed that the exploration process from blank areas survey to the identification of uranium reserves be divided into five stages:strategic selection,investigation and evaluation,prospecting,detailed prospecting and exploration based on the geological tasks of sandstone-type uranium deposits.Among them,the investigation and evaluation stage is further subdivided into three sub-stages:prediction,verification,and evaluation,which is the main application stage of geophysical and geochemical exploration technology.By summarizing the ability of geophysical and geochemical prospecting technology in solving geological problems of sandstone-type uranium deposits exploration,a geophysical and geochemical prospecting technology system for sandstone-type uranium deposits was constructed in combination with the exploration workflow of sandstone-type uranium deposits.And suggestions for the deployment of geophysical and geochemical exploration work in different exploration stages were proposed for some case of sandstone-type uranium deposits.
