About this title - Metasomatism in Oceanic and Continental Lithospheric Mantle
Twenty years have passed since Menzies & Hawkesworth extendedthe concept of metasomatism to mantle processes. The aim ofthis book is to gather together progress made on this topicsince then. Most of the 14 papers reported in the volume relyon in situ major and trace element analyses of minerals andglasses in mantle xenoliths, and deal with different kinds ofmetasomatic agents at variable fluid/rock ratios in tectonicsettings as different as intra-plate, mid-ocean ridge (ophiolites)and supra-subduction. The book contributes to the wide debateon the nature of the fluids migrating into the mantle wedge,as well as on the different residential times of the subductionsignature. In addition papers on intra-plate settings deal withthe problem of relating various metasomatic signatures to onesingle metasomatic event through an infiltration-reaction process.
