IV V Abstract Southwestern Yunnan is a key region for the understanding of the complex geological evolution of the Paleo-Tethys at the end of the Paleozoic and the formation of the 260 Ma-old Emeishan Large Igneous Province (ELIP), which hosts several important magmatic ore deposits. The same region is also intensively affected by Himalayan escape tectonics, with large-scale strike-slip movements. The most prominent Cenozoic fault zone in SW China is the NW–SE trending Red River-Ailaoshan Shearzone (RRASSZ) with left-lateral displacement of at least 300 km.
