The Dayushan (-Mufushan) dome is one of the largest Mesozoic plutons in the north SCB. Two phases of magmatic rocks form this composite pluton, including a Late Jurassic biotite granite of ∼150 Ma, and Early Cretaceous two-mica granites of 131–127 Ma. Host rocks of these plutons are micaschist, phyllite and slate, derived from Neoproterozoic to Early Paleozoic sandstone and mudstone protoliths. The contact metamorphism produced biotite, muscovite, garnet, and andalusite. The Dayunshan detachment is restricted to the NW border, bounding the Cretaceous to Paleogene basin filled by red beds. This detachment can be interpreted as the northeastern extension of the Ziyuan Detachment of the Yuechengling dome. At the southeast margin, a brittle normal fault strikes parallel to the Dayunshan detachment and probably develops in the similar tectonic setting.
