'Brenan' and 'Stalder' assume eclogite is 60 % garnet and 40 % clinopyroxene						

'Kessel' and 'Ayers' are measurements for natural eclogite or peridotite poly-phase assemblages						
'rutile' indicates 1 % rutile was assumed present in the residue.
						
The 6 Gpa data from Kessel et al., 2005b are for an aqueous supercritical phase
