The modeling results demonstrate that a sediment-derived melt produced at 1050 °C and 1.0 GPa changes its composition from rhyolitic to andesitic as it dissolves olivine and clinopyroxene and crystallizes orthopyroxene. The resulting reaction product possesses major and incompatible trace element compositions close to high-Mg andesites in the Setouchi volcanic belt, southwest Japan.
