    Petrogenesis of the Late Cretaceous Jiangba Volcanic Rocks and Its Indications for the Thinning of the Thickened Crust in Xiongmei Area, Tibet

    • 摘要: 江巴组火山岩是西藏雄梅地区近年来发现的火山岩,但其岩石成因尚不明确.通过开展系统的岩相学、地球化学、同位素定年示踪研究,结果表明英安质火山岩锆石U-Pb年龄为85.1±1.0 Ma,为晚白垩世.安山质和英安质火山岩显示出明显的埃达克质岩特征,主量元素显示出较高的SiO2和Al2O3含量及Mg#值;稀土元素整体呈轻稀土元素富集,重稀土元素强烈亏损,轻重稀土元素分异明显,(La/Yb)N值较高,无明显Eu异常;微量元素具有明显的高Sr,低Y、Yb和高Sr/Y值,相对富集Th、Zr和Hf,亏损Nb、Ta和Ti的特点;英安质火山岩锆石εHft)值均为正值,在+2.7~+7.1之间,指示有亏损地幔物质参与成岩作用;以上表明安山质和英安质火山岩可能形成于加厚新生下地壳拆沉的部分熔融并有亏损地幔物质的加入.流纹质火山岩具相对低的MgO、TiO2含量;LREEs富集、HREEs亏损,但轻重稀土元素分馏明显较安山质和英安质火山岩弱,微量元素富集Rb、Th和K,强烈亏损Eu,Sr,Ba,P和Ti,明显的负Eu异常,表明流纹质火山岩为地壳发生深熔而形成.综合对比江巴组火山岩的地球化学性质,表明班公湖-怒江缝合带中段昂龙岗日-班戈弧地区在晚白垩世期间存在一期板内加厚下地壳拆沉减薄事件.
