Abstract The study presents a detailed investigation of S-isotope systematics of pyrite from Cambrian-Ordovician sedimentary rocks along the eastern flank of the Michigan Basin, Ontario, Canada. Whole-rock and secondary-ion mass spectrometry (SIMS) pyrite analyses of 34S/32S were undertaken in association with a detailed petrographic investigation of the different crystal morphologies to better constrain the diagenetic history of the sedimentary rocks by informing about the processes of pyrite formation. The broad range of SIMS isotopic data (i.e., −37.1‰

沉积系统（密歇根盆地）的成岩演化：黄铁矿岩相学和 S 同位素微分析的见解

摘要 本研究详细介绍了加拿大安大略省密歇根盆地东侧寒武纪-奥陶纪沉积岩中黄铁矿的 S 同位素系统学。对 34S/32S 进行了全岩和二次离子质谱 (SIMS) 黄铁矿分析，并结合对不同晶体形态的详细岩相学研究，通过了解黄铁矿形成过程来更好地限制沉积岩的成岩历史. 广泛的 SIMS 同位素数据（即 -37.1‰
