The mass-independent minor oxygen isotope compositions (Δ′17O) of atmospheric O2 and CO2 are primarily regulated by their relative partial pressures, pO2/pCO2. Pyrite oxidation during chemical weathering on land consumes O2 and generates sulfate that is carried to the ocean by rivers. The Δ′17O values of marine sulfate deposits have thus...

三重氧同位素对陆地黄铁矿氧化的认识[地球，大气和行星科学]

大气中O2和CO2的质量无关的次要氧同位素组成（Δ'17O）主要受其相对分压pO2 / pCO2的调节。土地化学风化过程中的硫铁矿氧化会消耗O2并产生硫酸盐，并通过河流将其运送到海洋中。因此，海洋硫酸盐矿床的Δ′17O值...
