Strong local, not global, controls on marine pyrite sulfur isotopes

Understanding variation in the sulfur isotopic composition of sedimentary pyrite (δ34Spyr) is motivated by the key role of sulfur biogeochemistry in regulating Earth's surface...阐明沉积黄铁矿（sedimentary pyrite）硫同位素组成（δ34Spyr）的变化规律，其研究动因在于硫生物地球化学在调控地球表层环境中所发挥的关键作用……
