以往对地球历史过程中氧气浓度的推测,都来自各种间接的地球化学数据。而形成在卤水表面的原生石盐流体包裹体,可以捕获古代的卤水和大气,且由于石盐是无机矿物,捕获的古代大气不会与之发生反应,从而记录了原始的古代海水/湖水的成分和古代大气的成分。之前认为前寒武纪的大气氧气浓度在新元古代到寒武纪早期(5.5亿年左右)开始
Previous estimates of oxygen concentrations in the history of the earth came from a variety of indirect geochemical data. The native rock salt fluid inclusions formed on the brine surface capture ancient brine and the atmosphere, and the ancient atmosphere captured by the rock salt does not react with it as the rock salt is an inorganic mineral, thus recording the original ancient seawater / lake water Composition and composition of the ancient atmosphere. It was previously thought that Precambrian atmospheric oxygen concentrations started between the Neoproterozoic to the Early Cambrian (around 550 million years)
