This file encompasses 1 supplementary text, 3 Figures and 8 Tables, including protocols for the dating methods, sample information, geomorphic characteristics of the Zuogong, Markam and Weixi plateaux, new geochronology and thermochronology results, and input parameters of thermal-history modelling, as well as a compilation of available thermochronology data and exhumation/erosion rates of Cenozoic tectonics and river incision in eastern Tibet. Supplementary text (Materials and Methods): Zircon U-Pb geochronology, apatite fission track and zircon and apatite (U-Th)/He, and inverse modeling. Figure S1. Shaded topographic map and topographic swath superimposed by relict plateau surfaces and available thermochronological data around eastern Himalayan syntaxis. Figure S2. Geomorphic expression of the Zuogong, Markam and Weixi plateaux. Figure S3. Thermal histories of the rocks in the Zuogong, Markam and Weixi plateaux derived from QTQt inverse modeling. Table S1. Exhumation or erosion rates of Cenozoic tectonics and river incision, as well as million to millennial timescale erosion since stabilization of low-relief plateau surfaces. Table S2. Sample locations and dating information from low-relief plateau surfaces. Table S3. Zircon U-Pb geochronologic data analyzed by Laser-Ablation ICP Mass Spectrometery. Table S4. Apatite fission track data. Table S5. Apatite (U-Th)/He data. Table S6. Zircon (U-Th)/He data. Table S7. A collection of available thermochronological data. Table S8. Thermal history model input table modified from Flowers et al. (2015).
