| 摘 要： | 我国铀矿床主要划分为四大类型，包括花岗岩型铀矿床、火山岩型铀矿床、砂岩型铀矿床和碳硅泥岩型铀矿床。花岗岩型铀矿约占我国已探明铀矿总资源储量的三分之一以上，是我国重要的铀矿化类型。地球化学勘探方法对花岗岩型铀矿床勘查具有良好的效果。根据全国铀矿资源潜力评价项目研究成果，在大量研究中国花岗岩型铀矿化水系沉积物地球化学异常特征基础上，总结了一套对花岗岩型铀矿化勘查稳定的、行之有效的指示元素及其组合，确定了花岗岩型铀矿化地球化学异常模式，并以实例说明典型花岗岩型铀矿化异常模式。水柰沉积物地球化学异常是进行铀矿产预测评价的有效手段，对铀矿资源的潜力评价发挥了重要作用。

| Abstract: | Uranium deposits in China are mainly divided into four types： granite type, volcanic rock type, sandstone type and carbonaceous-siliceous-argillaceous rock type. Granite type uranium deposit accounting for China＇s more than one third proven uranium reserves, is an important type of uranium mineralization. Geochemical prospecting method has a good effect for the granite type uranium deposit exploration. According to the national uranium resource potential evaluation projects research and the study of geochemical anomaly characteristics of stream sediments for granite type uranium mineralization, this paper summed up a set of stable and effective indicator elements and combinations for granite type uranium mineralization exploration, geochemical anomaly model of granite type uranium mineralization was determined, and illustrates some typical granite type uranium mineralization anomaly model with examples. Geochemical anomalies of stream sediments is the effective forecasting means of uranium deposit evaluation, and have played an important role in the potential evaluation of uranium resources. |
