δ13Corg dynamics from Holocene aeolian deposits on the southern Tibetan Plateau

This dataset contains systematic experimental data derived from two typical Holocene aeolian sections (SGX and HZ) in the southern Tibetan Plateau, which is mainly used to support the research on Holocene vegetation succession patterns and corresponding climatic driving mechanisms across the southern plateau. The core uploaded data includes sediment depth, chronological age, raw and calibrated soil organic carbon isotope (δ¹³Corg) values, quantitatively estimated relative abundance of C4 plants, and percentage frequency magnetic susceptibility. All data were obtained through field sampling, laboratory testing and standardized model calculation. This dataset provides fundamental quantitative support for analyzing the spatiotemporal differentiation of vegetation evolution under different monsoon influence regimes on the southern Tibetan Plateau.
