Spinel crystals in mantle ultramafic xenoliths as the source of P-T conditions of alteration above the magma chamber beneath the Avacha Volcano (Kamchatka)
This study focuses on the ability of spinel crystals in ultramafic xenoliths, like zircon, to store the primary composition and structure when exposed to magma fluid flows or the thermal heating of ultramafic fragments in magma flows during volcanic eruptions. Mantle ultramafic rock xenoliths from e...
