We present a summary of peridotite in the Subantarctic (46 to 60°S) surrounding the Antarctic Plate. Peridotite xenoliths occur on Kerguelen and Auckland islands. Kerguelen islands are underlain by a plume whereas the Auckland Islands are part of co

Trace amounts of water dissolved in minerals affect density, viscosity and melting behaviour of the Earth’s mantle and play an important role in global tectonics, magmatism and volatile cycle. Water concentrations and the ratios of hydrogen isotope

The smooth seafloor area, located between 62 and 65°E along the ultraslow-spreading South West Indian Ridge, is dominated by exhumed and altered mantle rocks, with very minor basalts and gabbros. This amagmatic region of the global ridge system is a
