柴北缘都兰地区片麻岩的起源及形成时代:锆石U-Pb年代学、REE和Hf同位素的证据
都兰 片麻岩 锆石 U-Pb年代学 Lu-Hf同位素

在柴北缘HP-UHP变质带东端的都兰地区,大量正、副片麻岩中包裹有少量榴辉岩和超基性岩。这些片麻岩普遍显示出角闪岩相变质作用特征,但是野外关系和少量副片麻岩中的柯石英包体显示这些片麻岩与榴辉岩一起经历了超高压变质作用。本文通过两个片麻岩样品的锆石U-Pb年代学测定,结合稀土元素和Hf同位素分析,来确定这些片麻岩的原岩起源和变质作用时代。锆石的阴极发光图像分析、稀土元素特征、U-Pb定年结果显示锆石...

水泉沟杂岩体位于尚义 赤城断裂的南侧,侵位于太古宙桑干群变质岩中。岩体形成于晚加里东至早海两期。其稀土元素含量为8.543×10~(-6)~211.6×10~(-6),随着岩石的CaO、MgO、FeO、Fe_2O_3含量降低,SiO_2、K_2O、Na_2O含量增大,稀土含量减小,稀土分布模式由右倾直线型变为近平直的“~”型。在铅同位素构造模式图上杂岩体落在地幔铅同位素演化线附近。在ε_(Nd)-...
