The latter have compositions that replicate the situations where by diamonds kind, which include extreme melt depletion or superior pressures in eclogites. Even so, indicator minerals can be deceptive; a greater tactic is geothermobarometry, in which the compositions of minerals are analyzed as should they were in equilibrium with mantle minerals.[66]
