鹿井铀矿床成矿规律

Metallogenic Regularity of Lujing Uranium Deposit

鹿井(322)矿床主要有三组构造,其中QF2、F2、F1为矿区的三条主要断裂构造,构成了322矿床构造的基本骨架,形成了对矿化十分有利的构造格局。三个"结构层"的接触带对区内矿化起着一定的控制作用,内外接触带分布的矿体与接触面的起伏凸凹有着明显的关系。基于地质构造背景、断裂构造特征分析了成矿规律,并根据资料对矿床成矿区进行了预测,认为矿床深部及周边有找到大富矿的可能性。

The Lujing(322) deposit mainly has three groups of structures, QF2, F2 and F1 which are the main fault structures in the mining area. They constitute the basic framework of the structure of the 322 deposit and form a tectonic pattern favorable for mineralization. As for the contact zones of the three "structural layers", they play a certain role in controlling the mineralization in the area. The distribution ore body of the inner and the outer contact zone has an obvious relationship with concavo-convex veins of contact surface. The metallogenic rule is analyzed mainly through the geological structure background and the fault structure characteristics. According to the data, the metallogenic area of the deposit is predicted, and it is considered that there is a possibility to find large rich ore in the deep and surrounding areas of the deposit.
