We report high-precision multiple collector inductively coupledplasma mass spectrometry (MC-ICP-MS) analyses of Hf isotopiccompositions for 39 Kerguelen Archipelago volcanic rocks thatadd a new perspective to the temporal evolution of the Kerguelenmantle plume. Samples cover the entire range of chemical andSr, Nd and Pb isotopic variations reported for the archipelago,and vary in age from 29 to 0·1 Ma. Their Hf isotopiccompositions show the largest variation for an individual oceanicisland and  相似文献
