Supplementary datasets for Xueshan site research paper

This upload contains two datasets from a study of Neolithic pottery from Northern China: Dataset 1 (Table S1): Elemental composition data (via XRF) for 123 pottery sherds from the Xueshan site, featuring key variables like Period, Inclusion, Pottery Form, and concentrations of 9 elements. Dataset 2 (Table S2): A complete descriptive catalogue of all 153 observed samples, providing the full archaeological context for the analytical subsample. Dataset 3 (Table S3):A statistical table based on forming techniques, finishing methods, and decorative approaches documents the characteristics of samples from the Xueshan Phase I and Xueshan Phase II cultures. Dataset 4 (Table S4):Component Loadings (with Orthogonal Rotation) for Analysis of the Xueshan Dataset.本次上传包含一项针对中国北方新石器时代陶器的研究中的四份数据集： 数据集1（附表S1）：包含来自雪山遗址的123件陶片的元素组成数据（通过X射线荧光光谱法（X-ray Fluorescence，XRF）测得），涵盖年代、夹杂物、陶器器型以及9种元素的含量等核心变量。 数据集2（附表S2）：涵盖全部153件观测样品的完整描述性目录，为分析子样本提供了完整的考古背景信息。 数据集3（附表S3）：一张基于成型工艺、修整方式与装饰手法构建的统计表，记录了雪山一期文化与雪山二期文化出土样品的相关特征。 数据集4（附表S4）：针对雪山数据集开展分析得到的成分载荷（经正交旋转处理）。
