[Display omitted] •The TTGs originated from amphibole-dominated fractionation of dioritic magma.•Rocks from different Paleoproterozoic units share a common Neoarchean basement.•The southward-migrating magmatism is a tectonic response to the slab rollback. In the Guyang area, numerous late Neoarchean...
