Prospecting Potential and Geochemical Characteristics of Lingshan Granite,Northeastern Jiangxi
摘要
Abstract
Lingshan granite which is located in the east side of Songshugang Ta-Nb deposit mainly consists of albite and biotite gran-ite.The major elements of Lingshan granite show high SiO2,rich in Al2O3 and alkali,deleption of Ca,Ti,Mg,P and high A/CNK.The rare earth elements show low ∑REE,no fractionation between light and heavy rare earth elements,and very strongly negative Eu a-nomalies.The trace elements are rich in Rb,Cs,Ta,Th,U,Zr,Hf,and depletion of Ba,Srand Ti.The geochemical cheracteristics of the granites show that they belog to weakly peraluminous-peraluminous calc-alkaline-high-potassium calc-alkalin A-type granite.The geochemical cheracteristics of the granites also indicate that they are probably formed in the intracontinental lithospheric extensional en-vironment and the Nb2O5 content of Lingshan granite can reach up to 0.1％which shows that there is a very promising prospcting po-tential for Nb-rich rare metal deposit in the area.关键词
