The Wufengjian-Larelaxin volcanic-magmatic zone composed of the Late Jurassic volcanic rocks and Early Cretaceous intermediate-acidic intrusive rocks ((Larelaxin and Changlonghe superunits) is aligned in the northern part of the Bangong-Nujiang suture zone. The volcanic rocks and early (quartz) diorite and granodiorite (Tangzha-Nalielong and Fenghuoshan units) are assigned to the magmatic arc granites generated from the northward subduction and collision of the Meso-Tethyan Ocean and South Qiangtang block during the Late Jurassic to the Early Cretaceous, whereas the late granites (Aiyongco-Songmo unit) belong to the post-orogenic granites formed posterior to the northward subduction and collision cited above.
