Discovery and geological implications of Neoproterozoic metagranite in Jiaozhou Bay

  • 摘要:

    胶州湾为青岛市的半封闭海湾,对湾内基底岩石属性等的基础地质认识是青岛城市重大工程建设与未来城市规划的重要依据。本文借助锆石U-Pb测年的方法,在胶州湾区钻孔岩芯中首次发现新元古代变花岗岩质基底,其形成时代为约772 Ma,与区域上苏鲁造山带内广泛分布的新元古代花岗岩同期。钻孔内新元古代变花岗岩下部为早白垩世花岗岩侵入,花岗岩时代为约120 Ma,与毗邻的崂山花岗岩等岩体时代一致。钻孔岩芯中早白垩世花岗岩锆石与新元古代变花岗岩锆石的微量元素分布特征相似,但其含量值范围更窄。胶州湾区早白垩世花岗岩岩浆可能源自新元古代花岗质岩石的重熔。借助锆石Ti温度计计算获得胶州湾内新元古代变花岗岩与早白垩世花岗岩岩浆结晶温度均超过750 ℃,表明锆石结晶的岩浆源区呈水不饱和状态,暗示两期岩浆活动的动力学机制可能均与洋壳俯冲对应的“大地幔楔”模式无关。

    Abstract:

    Jiaozhou Bay is a semi-enclosed bay in Qingdao City in Shandong Peninsula, East China. Understanding the main geological frame of the basement rocks in the bay is crucial for large engineering projects and future urban planning in Qingdao. In this study, Neoproterozoic metamorphic granites (ca. 772 Ma) was discovered for the first time from drilling cores in Jiaozhou Bay .The basement rock is contemporaneous with Neoproterozoic granites that widely distributed in the Sulu orogenic belt. The lower part of the Neoproterozoic metamorphic granites in drilling cores was intruded by Early Cretaceous granites in age of ca. 120 Ma, which is consistent with the ages of adjacent Laoshan granites. The trace element distribution patterns of zircons in the Early Cretaceous granites and Neoproterozoic metamorphic granites in the drilling cores of Jiaozhou Bay are similar but showing a narrower range. The Early Cretaceous granite magma in the Jiaozhou Bay area might be derived from the remelting of Neoproterozoic granitic rocks. The crystallization temperatures of the Neoproterozoic metamorphic granites and Early Cretaceous granites determined by using zircon-Ti thermometer are both higher than 750°C, indicating that the source magma were water-undersaturated. This results suggest that the dynamic mechanisms of the two magmatic events may not be related to the oceanic subduction-related "Big mantle wedge" model.
