    Genesis of Late Cretaceous Qusang'gele Granitie in Central Lhasa Block, Tibet: Constraints by Geochemistry, Zircon U-Pb Geochronology, and Sr-Nd-Pb-Hf Isotopes

    • 摘要: 目前关于班公湖-怒江缝合带的构造演化时限及俯冲方向仍存在较多争议.中拉萨地块北缘发育众多白垩纪岩浆岩,是认识拉萨地块白垩纪时期的岩浆成因机制和构造动力学过程的有效探针.在对尼玛县曲桑格勒花岗正长岩体详细的野外地质调查基础上,对其岩相学、地球化学、锆石U-Pb年代学及Sr-Nd-Pb-Hf同位素特征开展了综合研究.曲桑格勒花岗岩的地球化学特征显示其具有较高的SiO2(75.23%~77.66%)、总碱(K2O+Na2O)(8.41%~8.94%)含量,低A12O3(11.96%~12.38%)、CaO(0.18%~0.55%)含量,里特曼指数(σ43)为2.05~2.33,铝指数(A/CNK)为0.99~1.03;富集大离子亲石元素(LILE)如Rb、Th、U、K、Pb,亏损高场强元素(HFSE)如Nb、Ta、P、Ti;轻稀土元素(LREE)富集,重稀土元素(HREE)相对亏损,轻重稀土分异偏低(LREE/HREE=2.42~5.00),呈现典型的“海鸥型”配分模式,具有强烈的负Eu异常(δEu=0.048~0.078),无明显Ce异常(δCe=0.739~1.471).锆石饱和温度计算结果显示曲桑格勒花岗岩的结晶温度为763.50~850.65℃,平均795.2℃,这些特征与A型花岗岩相符.通过LA-ICP-MS方法测得正长花岗岩锆石206Pb/238U年龄加权平均值为101±1 Ma(MSWD=0.45),表明曲桑格勒花岗岩的岩浆作用发生在晚白垩世早期,具有正的εHft)值(4.44~5.85),一阶段、二阶段模式年龄分别为536~592 Ma、702~781 Ma;(87Sr/86Sr)t为0.706 2~0.710 6、(143Nd/144Nd)t为0.512 315~0.512 441、εNdt)为-6.27~-3.82,(206Pb/204Pb)t为18.653~18.794、(207Pb/204Pb)t为15.709~15.731、(208Pb/204Pb)t为38.960~39.100;构造环境判别图解显示其具有拉萨地块与羌塘地块后碰撞阶段上地壳的变质泥质岩部分熔融的特点,因此曲桑格勒花岗岩应该是碰撞后伸展阶段岩浆活动的产物.结合区域构造演化历史认为曲桑格勒花岗岩源自加厚的拉萨地块中上地壳,受减薄减压效应影响深部前寒武纪变质基底发生部分深熔作用,形成具有以上地壳为主要岩浆源特点的A型花岗岩.
