Supplemental Material: Identification of two-stage northward subduction of the Bangong-Nujiang Meso-Tethys Ocean, Tibetan Plateau

Key Points

• The study reveals northward subduction occurring in two stages in the Tibetan Plateau region, shedding light on geological processes.
• Geochemical analysis using LA-ICP-MS shows detailed isotopic data for zircon U-Pb from sandstone and andesite samples.
• Trace-element compositions were assessed for Jurassic andesite and basalt samples to understand the evolution of the region.
• The findings highlight important interactions between oceanic and continental plates in forming the Tibetan Plateau.
