中国碳硅泥岩型铀矿地球化学指示元素特征及异常模式

摘要

根据全国铀矿资源潜力评价项目研究成果，在大量研究我国碳硅泥岩型铀矿地球化学异常特征的基础上，总结了一套对碳硅泥岩型铀矿勘查稳定且行之有效的指示元素及其组合，确定了碳硅泥岩型铀矿地球化学异常模式，并以实例说明。%Uranium deposits in China are mainly divided into four types:granite type,volcano rock type, sandstone type and carbonaceous siliceous argillaceous rock type. Carbonaceous siliceous argillaceous rock type account for about 7% China's proven uranium reserves. Based on the study of geo-chemical character of large amount of deposits in the national uranium resource potential evaluation pro-j ects,a set of stable and effective indicator elements and combinations for carbonaceous siliceous argil-laceous rock type uranium deposit was summarized in this paper and the geochemical anomaly model was determined by the case study.
