 | | for the megacrysts with the oxygen fugacity data for spinel lherzolite xenolites from the Shavaryn-Tsaram volcano (Geokhim., 1988, N.6, pp.783-793) suggests that their formation is characterized by the oxygen fugacity values close to the WM buffer equilibrium. |
 | | The conducted runs have shown that the oxygen fugacity of Cpx, Sa, and Gr are practically identical and are located 1-1.5 order higher than the buffer equilibrium of WM whereas the oxygen fugacity characteristic of Py megacryst is close to the WM buffer equilibrium. |
 | | The experiments were conducted according to the following scheme: lherzolite sample (olivine, clinopyroxene, orthopyroxene, and chromospinelides) (25 mg) and amphibolite sample (amphibole and plagioclase) (900 mg) were placed in the upper and lower parts of the capsule respectively. |
