Abstract

Analyses of igneous xenoliths containing high-iron-oxide melt (HIM) indicated that they resulted from crystal fractionation in a deep-crustal chamber of alkali basalt magma. HIM represented a primary magmatic phase. These findings were observed in globules of oxide melts dominated by iron and titanium. Fluid inclusion and mineral composition data showed immiscible separation of the HIM at magmatic temperatures. The HIM separation occurred during clinopyroxene accumulation in an alkali trachybasalt and continued during crystallization of amphibole and K-feldspar.
