lamproite magmas and thereby obtaining a direct indication of the potential for resorption diamonds. In this contribution, we present results detailed chemical analysis perovskite in kimberlite samples from several localities southern Africa, Russia Australia. Oxygen fugacity is estimated using oxygen barometer compared to estimates based on diamond population studies. The work are used evaluate general applicability kimberlites lamproites worldwide further constrain relationships between magma degree resorption. Samples methods
