| 摘 要： | 团岭花岗岩体侵位于大别山南部超高压变质带变质表壳岩中， 由细粒少斑二长花岗岩和中粒少斑二长花岗岩组成。通过岩石学、岩石化学、地球化学的研究， 确定其为Ｓ 型花岗岩， 源岩可能来自大别山变质杂岩。结合同位素资料， 认为其属燕山期花岗岩， 侵位机制为底辟式强力就位。

| Abstract: | The Tuanling granite intrusive that emplaced into the meta-crutose of UHPMB in the southern Dabie Mts is composed of fine-grained adamellite and medium-grained adamellite both with less phyenocrysts The petrological,petrochemical and geochemical study indicates that it is of S-type granite,whose source rock may be from the Dabie meta-complex The isotopic data suggest that it was formed in the Yanshanian period The emplacement is thought to be in a diapiric forceful mechanism |
