甘肃龙首山成矿带芨岭铀矿床地质特征及找矿潜力分析

芨岭矿床位于龙首山成矿带中段，区内以发育钠交代热液型铀矿床而备受瞩目。在研究前人资料的基础上，结合近几年的铀矿勘查工作，本文对矿床的地质特征进行了系统总结，查明铀矿化受马路沟断裂构造、钠交代岩和热液蚀变三者共同控制。本文通过对该区成矿条件和最新勘查成果的分析，认为在芨岭矿床深部和外围有较好的成矿潜力，值得开展进一步铀矿勘查工作。

Analysis on metallogenic geological characteristics and prospecting potential of Jiling uranium deposit in the Longshoushan metallogenic belt, Gansu province

The Jiling deposit is located in the middle of Longshoushan metallogenic, the sodium metasomatic hydrothermal uranium deposit was well-developed in this area. On the basis of previous data and combined with uranium exploration in recent years, the geological characteristics of uranium deposits are systematically summarized, and it is found that uranium mineralization is controlled by Malugou fault, sodium metasomatic rock and hydrothermal alteration. Through the analysis of the metallogenic conditions and latest exploration results in this area, it is considered that there has a great potential for the deep and periphery of Jiling deposit, and further uranium exploration is worth to be carried out.
