Petroleum geology data from hydrous and anhydrous pyrolysis residues (ver. 2.0, January 2023)

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: July 17, 2025 | Last Modified: 20230120
This data release contains programmed pyrolysis, organic petrographic (reflectance), and semiquantitative X-ray diffraction mineralogy data for subsurface coal and shale samples from around the world. Samples were subjected to hydrous or anhydrous pyrolysis experiments at varying temperatures and the resulting residues were analyzed via programmed pyrolysis and reflectance to document changes in thermal maturity.
