Wetlands are important providers of many ecosystem services, and wetland delineation determines land use options for an area. Geochemical and morphological changes can be determined through magnetic susceptibility, organic matter content, and x-ray fluorescence. Results showed consistency in organic matter percentage throughout the wetland sample, indicating an anaerobic environment, while the non-wetland samples showed decreased organic matter percentages with depth. The variations in Fe content seen are likely due to iron solubility in respect to pH.
