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). The EOG Two-O-Five #2H in Johnson County, Texas is a Mississippian Barnett Shale core within the Fort Worth Basin. Using XRF, the ability to model the mineralogy from geochemical analysis of elemental data can be determined on core samples. This study demonstrates the capabilities that XRF can provide for core analysis.Format: OnlineNo search engine accessChemostratigraphy and elemental analysis of the Mississippian Barnett Shale Formation using energy-dispersive x-ray fluorescence spectrometry, Fort Worth Basin, Johnson County, TexasText
