Whole-rock elemental and Sr-Nd-Hf-Pb-Fe isotopic evidence for the Initial ‘return’ of recycled paleo-Pacific oceanic crust observed in the early Cretaceous (~123 Ma) intraplate magmatism from eastern China

With the aim to seek if subducted paleo-Pacific slab had ‘returned’ through Mesozoic magmatism, we focus on an early Cretaceous (~123 Ma) diabase with OIB affinities in eastern China and provide robust whole-rock elemental and Sr-Nd-Hf-Pb-Fe isotopic evidence.
