Supplemental Material: Compositional change from high-Mg to low-Mg magmatism at ca. 150 Ma in the central Lhasa terrane, Tibet: Switching from advancing to retreating subduction of the Bangong Tethyan slab
Supplemental Text S1: Analytical methods. Table S1: LA-ICP-MS zircon trace-element results for intrusive rocks from the Zhegu, Wengmunong, and Dulu plutons in the central Lhasa subterrane. Table S2: LA-ICP-MS zircon U-Pb dating results for intrusive rocks from the Zhegu, Wengmunong, and Dulu plutons in the central Lhasa subterrane. Table S3: In-situ zircon Hf isotopes analyzed by LA-MC-ICP-MS for intrusive rocks from the Zhegu, Wengmunong, and Dulu plutons in the central Lhasa subterrane. Table S4: Whole-rock major and trace-element concentrations for intrusive rocks from the Zhegu, Wengmunong, and Dulu plutons in the central Lhasa subterrane, and for duplicate samples and measured USGS standards. Table S5: Compiled GPS positions and zircon U-Pb age data for the magmatic rocks from the central and southern Lhasa subterranes. Table S6: Compiled GPS positions and detrital zircon U-Pb age and Hf isotopic data for sedimentary rocks from Mesozoic strata in the central and southern Lhasa subterranes. Figure S1: Whole-rock TiO2, Al2O3, TFe2O3, MgO, CaO, and Na2O versus SiO2 diagrams (A–F) for intrusive rocks from the Zhegu, Wengmunong, and Dulu plutons in the central Lhasa subterrane. Figure S2: (A) Whole-rock εNd(t) and (B) whole-rock (87Sr/86Sr)i versus zircon U-Pb age diagrams for Middle Jurassic–Early Cretaceous igneous rocks in the central Lhasa subterrane. Figure S3: Ba/Th versus La/Sm (A), Zr versus SiO2 (B), and Ba versus SiO2 (C) diagrams for Middle–Late Jurassic igneous rocks in the central Lhasa subterrane.
