Rhyolitic volcanic rocks are generally characterized by rich alkali, silicon, aluminum,and poor calcium, magnesium. They have relatively high Rb,Th and rather low Ba,Sr,Ti,P,and exhibit obviouslv negative europium anomaly (δEu=0.16~0.44).The εNd values of the rhyolitic volcanic rocks range from -5.93 to -2022.Basalts and rhyolites in different cycles show clear geochemical variance.
流纹质岩石总体具富碱、富硅、富铝,贫钙、贫镁特征,其Rb、Th等元素的含量较高,而Ba、Sr、Ti、P等元素含量则明显偏低,并具显著的铕负异常(εEu=0.16'0.44),岩石的εNd值变化于-5.93~~-2.22.I、II旋回玄武岩和流纹岩在地球化学特征上均具明显变异。
