Objectives of this study include: 1) determining mineral composition of olivine, clinopyroxene, and orthopyroxene in the xenoliths; 2) examining individual chemical zoning characteristics or orthopyroxene, clinopyroxene, and olivine; 3) comparing mineral chemistry and zoning differences between xenoliths from different eruption styles; and 4) use xenolith compositions to determine lithospheric mantle pressure and temperature.
