Figure 4. (a) Mg/Si–Al/Si and (b) Ca/Si–Al/Si diagrams for the compositions of ultramafic xenoliths from Tumbusun-Dulga volcano: 1–4 – mantle beneath Tumbusun-Dulga volcano: 1 – undepleted, 2 – weakly depleted, 3 – strongly depleted, 4 – average mantle composition beneath Tumbusun-Dulga volcano, 5 – pyrolite [Ringwood, 1975], 6 – C1 chondrite [Jagoutz et al., 1979], 7 – primitive mantle [Hart, Zindler, 1986], 8 – same [Anderson, 1983], 9 – same [Palme and Nickel, 1985], 10 – same [Grachev, 1989], 11 – same [Kogarko et al., 1987].
