The qiongzhong and danxian batholiths, as the largest early mesozoic syntectonic granite intrusions in hainan island, are mainly composed of porphyritic biotite two-feldspars granitoids, in which alkali-feldspar phenocrysts and dark minerals are foliated mostly in we-direction . the granites are of metaluminous i-type . major and trace elements show co-variations with sio2, suggesting the fractional crystallization of plagioclase, hornblende, apatite and ti-fe oxides in the evolution of the granites 花岗岩的主量元素和部分微量元素成分与sio_2呈良好的相关关系,显示出明显的斜长石、角闪石、磷灰石和ti-fe氧化物等的分离结晶作用,总体上它们与大陆岛弧花岗岩的微量元素丰度和分布特征相似,系统地亏损ba、nb、sr、p和ti等元素。
