Geochemical characteristics indicate S-type granites and volcanic rocks depleted in sodium and enriched in potassium, with 62.42%～78.02% w(SiO2), 7.66%～9.13% w(K2O+Na2O), 1.18～2.62 w(K2O)/w(Na2O), and Rittmann index δ of 1.67～3.78. They are enriched in LREE with an average LREE/HREE ratio of 10.94×10-6, and generally depleted Eu with an minimum δEu less than 0.31 especially in the ignimbrite and biotite granite, which have experienced a significant process of separation and crystallization of plagioclases.ΣREE at the main stage of the magmatic activity decreases with time.
