Recycling of Paleo-oceanic crust: Geochemical evidence from early Paleozoic mafic igneous rocks in the Tongbai orogen, Central China

Abstract Crustal subduction generally develops from oceanic to continental subduction in collisional orogens, with the disappearance of previously subducted paleo-oceanic crust. However, it is not straightforward to trace the fate of subducted paleo-oceanic crust due to modification by subsequent continental collision. In this study, we...More
