摘要
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.
