- •
We present Sr–Nd–Pb isotope and geochemical data for Korean adakite-like plutons.
- •
Jindong plutons were formed by amphibole-dominated fractionation of arc magma.
- •
Bongnae plutons have adakite-like Sr/Y and La/Yb ratios, but are highly potassic.
- •
Bongnae adakites were formed by partial melting of lower CC and metasomatized SCLM.
- •
Heat source for the melting may be a slab breakoff-induced asthenosphere upwelling.
