早期的地球动力学过程模拟了地球表面，为生命的发展提供了合适的环境和能源。因此，研究古代地球化学循环是了解早期环境的物理化学条件（如原始海洋和大气的氧化还原状态）的一种有价值的方法。为了研究早期地球化学，测量古沉积岩中S、N和C的稳定同位素至关重要。在这里，我们回顾了太古代岩石中测得的硫和氮同位素特征，表明硫酸盐还原菌和化能无机生物生活在低氧环境中的古老性。
Early geodynamic processes modeled the surface of the Earth, providing suitable environments and energy sources for the development of life. Studying the ancient biogeochemical cycles is thus a valuable way to understand the physico-chemical conditions of the early environments, such as the redox state of the primitive oceans and the atmosphere. To investigate early biogeochemistries, the measurement of stable isotopes of S, N, and C from ancient sedimentary rocks is crucial. Here we review the sulfur and nitrogen isotopic signatures measured in Archean rocks that suggest the antiquity of sulfate-reducing bacteria and chemolithotrophs living in a low-oxygen environment.
