| 摘 要： | 大别造山带白马尖花岗岩体属燕山期侵入岩，为中生代大别山区岩浆活动的产物，为碰撞后花岗岩，锶，钕，同位素数据及稀土元素数据表明，白马尖花岗岩体为壳幔混合型，1．2－1．7Ga的钕模式年龄为其源岩的平均地壳存留年龄，北大别花岗岩类岩石的物质来源并不一致。

| Abstract: | The Baimajian granite in the Dabie orogen is a Yanshanian intrusion resulting from Mesozoic magmatism. It is post-collisional granite. Nd and Sr isotope and REE data show that the intrusion is of crust-mantle mixing type. Their Nd model age is 1. 2~1. 7 Ma, which is the average crustal retention age of their protoliths. The material sources of the granitoid rocks at Baimajian in the northern Dabie are different. |
