Dataset S1. The grandest of them all: the Lomagundi–Jatuli Event and Earth’s oxygenation

Dataset for δ13Ccarb values from 3.0–1.0 Ga and for Permian–Recent deposits. This file contains two worksheets. Worksheet 1 consists of published δ13Ccarb data spanning 3.0¬–1.0 Ga compiled from Refs. 80 and 81 and from publications that postdate those workers’ compilations (listed in Table S1). In compiling the updated dataset for 3.0–1.0 Ga, we excluded carbonate rocks associated with banded-iron formation and those from features of clear diagenetic origin (e.g. cements, concretions). Worksheet 2 contains published δ13Ccarb values compiled for marine and evaporite settings of Permian–Triassic, Messinian and Recent settings (sources listed in Table S2).

本数据集涵盖30亿至10亿年（Ga）以及二叠纪-现代沉积序列的碳酸盐碳同位素δ¹³Ccarb（δ13Ccarb）数据。本文件包含两个工作表：工作表1收录了已发表的、跨度为30亿至10亿年的碳酸盐碳同位素δ¹³Ccarb数据，该数据集汇编自参考文献80、81以及晚于该两项研究汇编成果的相关文献（详见附表S1）。在构建本次30亿至10亿年的更新版数据集时，我们剔除了与条带状含铁建造（banded-iron formation）相关的碳酸盐岩，以及明确具有成岩成因特征的碳酸盐岩（例如胶结物、结核）。工作表2收录了已发表的碳酸盐碳同位素δ¹³Ccarb数据，这些数据针对二叠纪-三叠纪、墨西拿期以及现代的海相与蒸发岩沉积环境汇编而成（数据来源详见附表S2）。
