Figure 5. $\mathrm{MgO-TiO_2}$ diagram for mica in xenoliths from the Roca Negra volcano in comparison with mica compositions in xenoliths collected elsewhere. 1, 2 – Biotite and phlogopite, the Roca Negra volcano; 3 – phlogopite in phlogopite pyroxenite xenoliths, Roccamonfina [Gianetti and Luhr, 1990]; 4 – average composition of phlogopite in spinel lherzolites [Ancochea and Nixon, 1987]; 5 – phlogopite in spinel lherzolite xenoliths hosted by basalts in the Baikal rift and Mongolia [Ionov and Hofmann, 1995]; 6 – garnet peridotite, Tanzania [Dawson, 1972], 7 – phlogopite in xenolith from the Roberts Victor kimberlite pipe [MacGregor, 1979]; 8 – phlogopite in xenoliths form the Premier Mine pipe, South Africa [Danchin, 1979]. The rectangle outlines the composition field of phlogopite in xenoliths of the MARID suite [Dawson and Smith, 1977].
