北京密云环斑花岗岩锆石U-Pb年龄和Hf同位素及其地质意义
Zircon U-Pb ages and Hf isotopes and their geological significance of the Miyun rapakivi granites from Beijing, China

摘要: 密云岩体位于华北克拉通东部,由环斑花岗岩和斑状黑云母花岗岩组成,是典型 A 型环斑花岗岩岩体之一。锆石的 LA-ICPMS U-Pb 年代学研究表明,密云环斑花岗岩形成于1681±10Ma 和1679±10Ma,而围岩片麻岩的原岩形成于2521±14Ma。锆石的 LA-MC-ICPMS Hf 同位素研究表明,太古代片麻岩来源于亏损地幔物质的部分熔融,从而表明2.5 Ca 是华北克拉通地壳重要的生长期;环斑花岗岩中锆石 Hf 同位素组成为δ_(Hf)(t)=~-5,两阶段模式年龄为 T_(DM2)=2.6~2.8Ga,表明它们来源于太古代新生地壳的部分熔融,密云环斑花岗岩侵位于华北克拉通大陆裂解、伸展环境,可能与全球古元古代未期Columbia 超大陆的裂解有关。
