Trace element evidence for diverse origins of superheavy pyrite in Neoproterozoic sedimentary strata

Data S1 includes all LA-ICP-MS analyses (3632) used for supervised machine learning model training and testing (including in-sample-locality and out-of-sample-locality testing). The data were also used for HCA and PCA analyses. Data S2 includes LA-ICP-MS trace element analyses of samples from Cui et al. and Xiao et al. projects.

数据集S1包含共计3632组激光剥蚀电感耦合等离子体质谱法（LA-ICP-MS）分析数据，用于监督机器学习模型的训练与测试，测试涵盖样本内点位与样本外点位测试。该数据集同时用于层次聚类分析（Hierarchical Cluster Analysis，HCA）与主成分分析（Principal Component Analysis，PCA）。数据集S2包含来自Cui等人与Xiao等人研究项目的样品的LA-ICP-MS微量元素分析数据。
