Methodology
  • X-ray absorption spectroscopy (XAS) data was collected on manganese standards at beam line 4-1 at the Stanford Synchrotron Radiation Lightsource (SSRL). Data collection and analysis is described in detail in the accompanying manuscript and in the ReadMe file associated with this dataset.
Description
  • Manganese in the sedimentary record has been interpreted by many as a powerful redox proxy for paleoenvironments, and yet very little work has been done to ensure that the manganese-rich minerals in the rock record are actually recording primary signals. In the accompanying manuscript, we present an in-depth characterization of the manganese mineralogy from two correlated regions recording the Transvaal Supergroup in South Africa with markedly different alteration histories to investigate if there can be post-depositional emplacement of manganese-rich minerals. The data uploaded here are X-ray absorption spectra of (1) manganese standard minerals that were useful in our analyses and (2) minerals from an important well-characterized sample that may be useful as comparative standards in future studies.
