福建丁家山铅锌矿稀土元素特征
|
摘要
通过对福建丁家山矿区铅锌矿床不同类型岩石和矿石的稀土元素地球化学特征的研究,探讨了岩石和矿石中稀土元素地球化学行为。结果显示,丁家山铅锌矿区的稀土元素呈现轻稀土富集、重稀土亏损的地球化学特征,说明成矿流体和围岩具有继承性,丁家山铅锌矿虽呈层状,但该矿床具有热液矿床的特征。热液在运移过程中,随着温度不断降低,在成矿有利部位形成低温蚀变矿物,如绿泥石、绿帘石、阳起石等,同时伴随着Cu、Pb、Zn、Ag等成矿元素和稀土元素的沉淀富集。
This paper analyzed the REE geochemistry features of various rocks and ores in the Dingjiashan Pb-Zn deposit of Fujian Province and studied their REE geochemistry performance.The results show that rare earth elements of this area are characteristic of LREE-enrichment and HREE-loss,which suggests that the ore-forming fluid is inherited from surrounding rock.Despite of the stratified structure of this deposit,it still has the features of hydrothermal deposits.In hydrothermal migration,as the temperature decreases,the low-temperature altered minerals were formed in the favorable areas of mineralization such as chlorite,epidote,actinolite,accompanied with the deposition and enrichment of Cu,Pb,Zn,Ag and other oreforming elements and rare earth elements.
