Figure 6. $\mathrm{MgO-TiO_2}$ diagram for amphibole in xenoliths from the Roca Negra volcano in comparison with mica compositions in xenoliths collected elsewhere. 1 – Amphibole in xenoliths from the Roca Negra volcano; 2 – amphibole in spinel lherzolite xenoliths from the Baikal rift, Rhine graben, and Mongolia [Ionov and Hofmann, 1995; Ionov et al., 1984; Witt and Seck, 1989]; 3 – amphibole in pyroxenite xenoliths from the canary Islands, Frank Seamount in the Indian Ocean, the Cape Verde Islands in the Atlantic Ocean, Murcia, and the Tien Shan [Kogarko, 1990; Munoz et al., 1974; Reid and Le Roex, 1988; Sagredo, 1969]; 4 – amphibole in pyroxenite xenoliths from the Tien Shan [Dobretsov and Dobretsova, 1975]. The rectangle contours the amphibole composition field in xenoliths of the MARID suite [Dawson and Smith, 1977].
