    Petrogenesis and Geological Implications of Early Jurassic Granodiorites in Renqinze Area, Central Part of Southern Lhasa Subterrane

    • 摘要: 青藏高原拉萨地块南部新特提斯洋的打开和俯冲时间,目前还未得到统一的认识.南拉萨地块上广泛发育早中生代花岗质岩石,为探讨亚洲-印度大陆碰撞前的新特提斯洋俯冲过程提供了天然样品.对仁钦则地区一套花岗闪长岩进行了详细的年代学、元素和同位素地球化学分析.锆石U-Pb定年结果显示,这套花岗闪长岩主要形成于180 Ma左右,为早侏罗世岩浆活动产物.仁钦则花岗闪长岩具有相对较高的SiO2含量(62.77%~64.18%)、较低的K2O/Na2O(0.29~0.60)和A/CNK值(0.90~0.98),表明其属于Ⅰ型钙碱性岩石系列.岩石明显富集Ba、U等大离子亲石元素而亏损Nb、Ta等高场强元素,具有弧岩浆岩的地球化学特征.花岗闪长岩具有较高的CaO含量、较低的全碱和Al2O3含量,与含水的变基性岩部分熔融形成的熔体成分一致.锆石Ti和全岩Zr饱和温度计结果显示花岗闪长岩可能形成于下地壳源区.仁钦则花岗闪长岩具有较低的(87Sr/86Sr)i(0.703 671~0.703 794)、较高的εNdt)(5.41~5.66)和锆石εHft)值(12.6~14.8),进一步表明其很可能为新生基性下地壳的部分熔融产物.综合分析认为,仁钦则花岗闪长岩主要形成于新特提斯洋北向俯冲背景之下,新特提斯洋的打开时间至少在晚三叠世之前.
