Elemental Chemostratigraphy of the Cottage Grove Hole MP-18 Core: Implications for Litho- and Hydrostratigraphy in Southcentral Wisconsin

Part of a larger regional study of the Eau Claire Formation, the core, from Dane County, Wisconsin, was tested using a portable x-ray fluorescence (pXRF) elemental analyzer. The report presents the data set and discusses lithologic interpretations, subsurface lithostratigraphic correlations, and hydrostratigraphic frameworks. Includes photos of the core.
