Abstract:

苏鲁超高压变质带南部的花岗岩体为中生代的Ⅰ型花岗岩,侵入到围岩片麻岩中,属碰撞后花岗岩。SiO2含量为56.15%~66.67%,Na2O含量为3.58%~4.54%,K2O含量为2.16%~4.58%,Alk为6.93~8.62%。里特曼指数为2.7~3.1,属于高钾钙碱性岩石。δEu=0.76~0.82,为弱的负铕异常。围岩片麻岩SiO2含量较高,为70.55%~77.28%,Na2O为3.12%~5.39%,K2O为1.78%~6.22%,δEu为0.38~0.59,具有明显的负铕异常。花岗岩与片麻岩的地球化学特征有明显差别,表明两者在成因上关系不大,花岗岩的源岩为未出露地表的中下地壳岩石。拆沉模式可较好地解释碰撞后花岗岩与超高压变质岩的“共生”现象。
