这篇论文概述了地球表面持续了二十亿年的过渡性氧化过程，利用沉积硫酸盐中的高分辨率氧同位素（Δ′¹⁷Osulfate）记录作为大气氧分压（pO₂）的代理指标。研究通过将新数据与现有的硫同位素数据结合，提出了地球大气氧化历史的三个主要阶段：从无氧状态（4.0 Ga至2.4 Ga）到低且波动的氧水平（2.4 Ga至0.41 Ga），再到现代水平（0.41 Ga至今）。作者们发现，在第二阶段（1.0 Ga至0.41 Ga）的新元古代负碳同位素漂移事件（δ¹³Ccarb excursions）中，Δ′¹⁷Osulfate 和 δ³⁴Ssulfate 的耦合下降，表明大气氧输入增强引发了短暂的海洋氧化脉冲。这些发现支持了一个动态且漫长的气-海共同氧化历史，解释了新元古代碳循环的异常和复杂生命的阶段性崛起。References:Wang H, Li C, Peng Y, et al.
