Tectonic interpretation after Kapp and DeCelles (2019). (A) Middle–Late Jurassic accelerated slab rollback during formation of the Zedong Arc drives the opening of an extensional backarc basin. This is consistent with the generation of the late-stage, juvenile (asthenosphere derived) Yeba volcanics (Liu et al., 2018). (B) Late Cretaceous slab rollback results in the opening of a backarc ocean basin.
