Data for: Quantifying proportions of different material sources to loess based on a grid search and Monte Carlo model: A case study of the Ili Valley, Central Asia.

The relative abundances of geochemical elements determined by XRF in the near-surface loess (58 samples), topsoil type-I (17 samples), topsoil type-II (14 samples) and modern riverbed sediments (5 samples). Furthermore, also including the sand content in different types of topsoil from the Ili Valley (115 samples). All data is presented in tables within the manuscript.本数据集涵盖通过X射线荧光光谱法（XRF）测定的近地表黄土（58个样本）、I型表层土壤（17个样本）、II型表层土壤（14个样本）及现代河床沉积物（5个样本）的地球化学元素相对丰度数据；此外还包含伊犁河谷不同类型表层土壤的砂粒含量数据（共115个样本）。所有数据均以表格形式呈现于本手稿中。
