Alkali basalts from the Kerguelen islands have entrained many mantle peridotites (harzburgites and dunites) in addition to various other ultramafic and mafic xenoliths. The harzburgites and the dunites were equilibrated in the spinel peridotite stability field (T = 850-1150°C). They attest to the ex...
