Global variations in abyssal peridotite compositions
JM Warren - Lithos, 2016 - Elsevier
Abyssal peridotites are ultramafic rocks collected from mid-ocean ridges that are the
residues of adiabatic decompression melting. Their compositions provide information on the …

Garnet-field melting and late-stage refertilization in 'residual'abyssal peridotites from the Central Indian Ridge
The role of residual garnet during melting beneath mid-ocean ridges has been the subject of
many recent investigations. To address this issue from the perspective of melting residues …
