Assessing the influence of diagenetic processes on iron and manganese geochemistry in anoxic sedimentary settings: Implications for the paleo-redox proxies

Data S1 includes major cation data for the water column of the Middle Island Sinkhole (MIS; Lake Huron). Data S2 includes major cation data for the porewaters of two cores from MIS. Data S3 includes Fe, Mn, and Al data for two sediment cores in MIS. Data S4 includes normalized Fe K-edge XANES spectra for standards, and samples from the Cretaceous Niobrara Formation.数据集S1包含休伦湖中岛沉陷坑（Middle Island Sinkhole，简称MIS）水柱的主要阳离子数据。数据集S2包含采自MIS的两个岩芯孔隙水的主要阳离子数据。数据集S3包含MIS内两个沉积岩芯的铁（Fe）、锰（Mn）与铝（Al）数据。数据集S4包含标准样品以及白垩纪尼欧布拉拉组样品的归一化铁K边X射线吸收近边结构（XANES）光谱。
