摘要
<正>We used 1290 published and 8 newly acquired zircon U-Pb ages of granitoids from the Da Hinggan Mountains and adjacent areas(Fig.1).According to these data,Phanerozoic granitoid magmatisms in these areas occurred during 517-102 Ma,and they can be subdivided into five dominant stages(Fig.2):Early Paleozoic(517-410 Ma),Middle Devonian-Early carboniferous(400-340 Ma),Late Carboniferous-Early
