... Nd and 87 Sr/ 86 Sr isotopic data and REE modelling indicate that the magmas were formed by 1–2% melting of an ocean-island basalt (OIB)-like source containing about 3–4% garnet. Deviations from OIB are explained by mobilization of incompatible elements from potassic layers in the lithosphere during...
