Short summary
Plate tectonics theory is the motion of rocky plates (lithosphere) over ductile zones (asthenosphere). The causes of the lithosphere–asthenosphere boundary (LAB) are controversial; however, petit-spot volcanism supports the presence of melt at the LAB. We conducted geochemistry, geochronology, and geochemical modeling of petit-spot volcanoes on the western Pacific Plate, and the results suggested that carbonatite melt and recycled oceanic crust induced the partial melting at the LAB.
