Abstract:The Yanshanian granites in Yifeng Area is located in Jiuling tungsten molybdenum tin copper gold polymetallic fluorite kaolin mineralization subzone, where holds more than 10 porclain stone deposits (lithium-bearing). Through a series of studies of Dagang and Baishihuashan porclain stone deposits (lithium-bearing), the ore-bodies are mainly hosted in the medium-fine grainedmuscovite granite of Early Cretaceous Baishuidong rock mass. The major elements of the Yanshanian granites show high SiO2(70.01%—72.74%), Al2O33(14.75%—15.85%), Na2O(2.21%—3.96%), low CaO(0.07%—0.77%), and high A/CNK（A/CNK＞1.25）, which indicates the granites belong to highly differentiated peraluminous granite; the rare earth elements show low ∑REE (∑REE=3.30×10-6—39.41×10-6), slightly fractionation between light and heavy rare earth elements, and strong negative Eu anomalies, the trace elements are rich in Cs, Rb, Ta, P and depletion of Ba、Nb、Ti, which are similar to the S-type granite. In conclusion, the Yanshanian granites in Yifeng area are highly differentiated S-type peraluminous granite which are formed in a co-collision environment and originated from the partial melting of crustal argillaceous components.
