Geochemical data of bulk and multi-size fraction samples from the KMG red clay section

1. This file is a supplement to the manuscript “Enhanced Continental Weathering Contributed to the Termination of the Middle Miocene Climatic Optimum” by Wu et al. (2025, Geophysical Research Letters). 2. This file compiles bulk and multi-size (<5, 5–20 and >20 μm) fraction samples from the KMG section. 3. If you plan to use the compiled dataset in this file, please cite the paper of Wu et al. (2025).1. 本文件为Wu等人（2025年发表于《Geophysical Research Letters》）的研究论文《增强大陆风化作用促成中新世中期气候适宜期（Middle Miocene Climatic Optimum）终结》的补充材料。 2. 本文件整合了KMG剖面的全样及多粒级（<5、5–20及>20 μm）组分样品。 3. 若您计划使用本文件中的整合数据集，请引用Wu等人（2025年）的研究论文。
