Chemostratigraphy and elemental analysis of the Mississippian Barnett Shale formation using energy-dispersive x-ray fluorescence spectrometry, Fort Worth Basin, Johnson County, Texas

nergy-dispersive x-ray fluorescence (ED-XRF) is a technique used in a wide variety of disciplines to provide an analytical elemental perspective. Within the field of geology, XRF is a method to characterize rocks and investigate both major and trace elements in a given sample. This easy to use, portable piece of machinery is advantageous because it requires minimal sample preparation, provides quick analysis time, and is relatively cost-effective and non-destructive to the samples. When coupled with a methodology that enables it to convert elementary raw data analysis into a mineralogical composition, XRF produces results that are analogous to those that can be obtained through full-scale x-ray diffraction (XRD).
