Development of USGS Geochemical Reference Materials
The project focus will be the development of traditional and microanalytical reference materials that support USGS geochemical investigations. Development of new microanalytical reference materials allows USGS scientists and outside customers to examine a greater range of sample types while maintaining a high degree of data reliability.
Variability in results from mineralogical and organic geochemical interlaboratory testing of U. S. Geological Survey shale reference materials
The expansion of unconventional petroleum resource exploration and production in the United States has led to an increase in source rock characterization efforts, particularly related to bulk organic and mineralogical properties. To support the analytical and research needs of industry and academia, as well as internal work, the U.S. Geological...
Birdwell, Justin E.; Wilson, Stephen A. High microscale variability in Raman thermal maturity estimates from shale organic matter
Raman spectroscopy has recently received attention as a means to estimate thermal maturity of organic matter in petroleum generating source rocks to complement more traditional approaches such as vitrinite reflectance and programmed pyrolysis. While many studies have observed positive correlations between...
