Evaluating pXRF instrument performance using reference materials
The portable X-Ray Fluorescence (pXRF) instrument provides fast, real-time, non-destructive, multi-element geochemical data (i.e. elemental concentrations) on rocks and minerals at a relatively low cost and with minimal sample preparation. This study quantifies the precision and accuracy of measurements collected by the WGNHS pXRF on reference materials...-

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. -
