对广东和寮铅锌矿不同岩石样品进行稀土元素地球化学特征的测试对比分析,结果表明,四种岩石样品稀土元素总量存在差异,矿石稀土元素总量介于混合岩和大理岩之间,且更接近于这两种岩石,表明了铅锌矿的形成与混合岩和大理岩关系可能更为密切;铅锌矿矿石的稀土元素配分模式曲线与混合岩和大理岩极为相近,轻重稀土的富集程度介于混合岩和大理岩之间,这也反映了区内铅锌矿的形成与混合岩和大理岩有着密切的关系;混合岩和大理岩为铅锌矿的主要矿源层,在混合岩化作用形成混合岩的过程中,混合岩化作用产生的热液与围岩大理岩发生反应,生成了富含铅锌矿的矿石。所以,在研究区今后进行矿产勘查时,应更加关注混合岩和大理岩的接触地段。
The results show that the total amount of rare earth elements in four rock samples is different, the total amount of rare earth elements in the ore is between the mixed rock and marble, And more close to the two kinds of rocks, indicating that the formation of lead-zinc ore and the relationship between mafic rocks and marble may be more closely; lead-zinc ore ore REE distribution pattern curve and mixed rock and marble are very similar to light and heavy rare earth The degree of enrichment is between that of the mixed rock and the marble, which also reflects that the formation of lead-zinc in the area is closely related to the mixed rock and marble. The mixed rock and marble are the main source rocks of lead-zinc mine. During the formation of mixed rocks by mixed lithification, the hydrothermal fluids generated by the mixed rockification reaction react with the surrounding rock and generate ore that is rich in lead-zinc ore. Therefore, in the future research area of mineral exploration, should pay more attention to the contact area of the mixed rock and marble.
