1. 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
