| 摘 要： | 通过对雪山花岗闪长岩中锆石SHRIMP U-Pb同位素年龄测定,获得了14个测点构成的谐和线上交点年龄数值为2 491±5 Ma（MSWD=0.43）,该年龄基本代表了花岗闪长岩的形成时间。从区域地质条件分析,将雪山岩体的形成时代确定为新太古代晚期。

| Abstract: | Based on the zircon SHRIMP U-Pb dating research of the granodiorite of the Xueshan intrusion in Yishui County of Shandong province,concordant ages of 2 491±5 Ma（MSWD=0.43） composed by 14 points is obtained.It is regarded that this age can represent the formation age of the granodiorite.According to regional geological condition,it is conclued that the Xueshan intrusion is formed in the late stage of Newarchean. |
