我校閱並稍微修改了此文而且將它附加到我原作的下面。因此f1371就變更豐實了。 -
The low - ti series show variable degrees of nb - ta depletion in primitive mantle - normalized spidergrams with slightly enriched to depleted nd isotopic compositions, whereas the transitional series exhibit similar geochemical features to emii - oib and have transitional characteristics between the high - ti and low - ti rocks. all three groups show no continuous shift in major and trace elements and cannot be regarded as different phases during magma differentiation process. on the basis of normalization to mgo = 8 %, the high - ti diabases have the lowest sig, nag and highest tig and peg
通過詳細的巖石學和元素-同位素地球化學研究,這些巖石具有各自不同的地球化學特徵,其中高ti系列的低la nb 、 zr nb比值和虧損的nd同位素組成顯示其類似於oib的特徵,過渡ti系列則顯示出emii - oib的特徵,而低ti系列則高la nb 、 zr nb比值和變化的nd同位素組成顯示出一定比例的富集巖石圈地幔或地殼物質的參與。
