Subduction Initiation of the Southern Branch of the Paleo‐Asian Ocean in the Middle Ordovician in the Southern Beishan Orogen

Subduction Initiation of the Southern Branch of the Paleo‐Asian Ocean in the Middle Ordovician in the Southern Beishan Orogen

Abstract The subduction initiation and the early‐stage tectonics of the southern Paleo‐Asian Ocean have rarely been discussed. To address these problems, we report new geochemical and geochronological data of arc‐related volcanic rocks in the Huaniushan arc of the southern Beishan. Basaltic andesite...
