| 摘 要： | 保梅岭中粗粒黑云母钾长花岗岩是我们在海南岛首次发现的加里东期花岗岩。岩石以富硅、碱，贫镁、钙，较小的稀土总量和轻重稀土比率，特别低的钡、锶含量，明显的负铕异常为特征。它是加里东期主造山运动之后地壳隆升阶段侵位的，属晚（非）造山花岗岩类

| Abstract: | Baomeiling medium mega grained K fledspar granitite is Caledonian granite which was firstly found in Hainan Istand.It is characterized by rich in SiO 2,K 2O Na 2O,poor in MgO,CaO,specially low in Ba,Sr,lower in total REE,Eu and LREE/HREE ratio,obviously negative Eu anaomaly.Lithogrochemical characteristics show that it is a residual later rock unit in an old granitoid superunit,and was formed at the uplift stage after Caledonian main fold orogenic movement. |
