Plio-Pleistocene climate record on the Tibetan plateau (4.3 Ma to 0.8 Ma). A total of 344 samples were collected and analysed for CaCO₃, grain size, TN, TOC, C/N ratio, and δ¹³C_org. A subset of 275 samples were also analysed for carbonate δ¹⁸O_c and δ¹³C_c analyses. 57 samples were analysed for Δ₄₇ composition, which was used to estimate local mean annual air temperature.

Supplement to Cheng F. et al., Alpine permafrost could account for a quarter of thawed carbon based on Plio-Pleistocene paleoclimate analogue, Nature Communications.
