New available geological and geochemical data of volcanic rocks indicate the coexistence of an islandarc system in the Gangdese and an extensional setting in the Himalayas during the Early to Middle Permian. Peraluminous Stype granites near Pikang (~263 Ma), the Songdo eclogite of the same metamorphic age (~262 Ma), and the regional angular unconformity between the Middle and the Upper Permian from the same geotectonic location suggest that the presentday Gangdese Retroarc Uplift Belt experienced a syncollisional orogeny at the latest Middle Permian (~263 Ma).
新的地质和地球化学资料显示早-中二叠世时俯冲背景和伸展背景共存于现今的冈底斯带和喜马拉雅带,中二叠世末期(大约263 Ma)侵位的皮康过铝质S型花岗岩以及同期发生的松多榴辉岩的高压变质作用和区域性角度不整合指示现今的冈底斯弧背断隆带在那时经历了同碰撞造山事件。
