摘　　要：通过对内蒙古色尔腾地区白彦花斜长花岗岩锆石U_Pb法年龄的分析 ,确定该岩体的形成年龄为 2 40 0～2 5 0 0Ma ,结合区域地质特征厘定其形成于新太古代。Based on survey and research, the authors have found a suite of Neo-Archaean intrusive rocks composed of plagiogranite, quartz diorites, and diorites in Seerteng area, Inner Mongolia. Isotopic dating of plagiogranite indicates that the age of the rocks is at 2?400～2?500 Ma. According to isotopic age and regional geologic characteristics, the authors hold that the intrusive rocks might be products of Neo-Archaean.
