Garnets mantle-derived xenolith

Carbonate is rarely found in mantle-derived xenoliths. It has been found in mantle-derived garnets (McGetchin and Besangon, 1975 Smith, 1987), clinopyroxenes (Hervig and Smith, 1981) and in rare xenoliths (e.g., Ionov et al., 1993a, 1996 Lee et al., 2000 Laurora et al., 2001).
