A basanite dyke in the Kerguelen Archipelago contains abundant composite mantle xenoliths consisting of spinel-bearing dunites cross-cut by amphibole-rich veins. Two types of veins (thick and thin) have been distinguished: the thick veins represent almost complete crystallization products of highly...
