Short summary

The occurrence of boninite in the northern Zambales ophiolite is reported. Boninite is a relatively rare high-magnesium andesite that is intimately associated with early arc volcanism and the initiation of subduction zones. Taken as a whole, the geological and geochemical characteristics of Zambales and Izu-Ogasawara–Mariana forearc volcanic sequences enables a refined geodynamic reconstruction of subduction initiation.
