Description

Volcanoes with ocean island basalt (OIB)-like characteristics occur in all settings. Their origin is particularly enigmatic when they occur in close spatial and temporal association with subduction-related volcanism (e.g., back-arc basin basalts; BABB). A set of cognate enclaves and a late-intruding dike from Dokdo Island (Republic of Korea) were used to probe an intraplate mafic alkaline plumbing system developed in a back-arc basin. Detailed petrography, mineral chemistry, and whole-rock ma...
