庙背垅地区位于诸广山岩体中段鹿井铀矿田南部，也是重要的铀成矿区。通过对区内控矿构造基本特征、构造岩及蚀变分带特征、构造控矿及铀矿化特征进行研究，探讨了构造–岩浆活动与铀成矿成因关系，认为庙背垅铀矿床属于中低温热液充填交代成因矿床，且密切与煌斑岩脉、辉绿岩脉等基性岩脉密切相关，提出了本区新的找矿方向及思路。 Miaobeilong area is located in the south of Lujing uranium deposit in the middle of Zhuguang Mountain rock mass, and is also an important uranium metallogenic area. Based on the study of the basic characteristics of ore-controlling structure, tectonite and alteration zoning, structural ore-controlling and uranium mineralization characteristics, the relationship between tecton-ic-magmatic activity and uranium mineralization is discussed. It is considered that Miaobeilong uranium deposit belongs to medium-low temperature hydrothermal filling metasomatic deposit, and is closely related to basic dikes such as lamprophyre veins and diabase veins. A new pros-pecting direction and idea in this area are proposed.
