| 摘 要： | 大别山地区的主薄原，天柱山，白马尖三个花岗岩体主要由花岗闪长岩和二长花岗岩组成，岩石为准铝质到弱过铝质（ACNK＝0．78－1．05），为轻稀土富集型，富含大离子亲石元素Rb,Th，以及稀土元素La,Ce,Nd,Sm，通过花岗岩地质学，岩石学和地球化学研究，认为这在个岩体的地球化学特征相似，属I型花岗岩，其构造背景为碰撞后环境。

| Abstract: | Zhubuyuan,Tianzhushan and Baimajian intrusives in Dabieshan area,are mainly composed of granodiorite and monzogranite.They are metaluminous (ACNK=0.78～1.05) and rich in LREE.They are also rich in LILE:Rb and Th,and REE,La,Ce,Nd and Sm.The data show that the three granitic intrusives are I-type granite and formed in post-collision. |

| Keywords: | Dabieshan Geochemical characteristics I type granite post collision |
