In this paper, geochemical data of the major and trace elements are analyzed. Based on these data, together with some other achievements, geochemical comparisons between and within these two cycles are discussed, and their petrogenesis are constrained. The major element characteristics indicate that their variation was well dominated by the mineral assemblage modal which are controlled by fractional crystallization of the rocks. Besides the positive Eu anomaly, LREEs are clearly fractionated, while no fractionation of HREEs occurs.
