Solid organic matter (OM) in sedimentary rocks produces petroleum and solid bitumen when it undergoes thermal maturation. The solid OM is a 'geomacromolecule', usually representing a mixture of various organisms with distinct biogenic origins, and can have high heterogeneity in composition. Programmed pyrolysis is a common conventional method to reveal bulk geochemical characteristics of the dominant OM while detailed organic petrography is required to reveal information about the biogenic origin of contributing macerals. Despite advantages of programmed pyrolysis, it cannot provide information about the heterogeneity of chemical compositions present in the individual OM types. Therefore, other analytical techniques...

Organic Petrography and Diagenesis of Leonardian Mudrocks and Carbonates, Midland Basin, Texas (2018)
As part of a larger study, organic petrographic features of Leonardian Wolfcamp A repetitive siliceous and calcareous mudrock and fine-grained carbonate lithofacies cycles occurring in the R. Ricker #1 core from Reagan County, Midland Basin, Texas were evaluated. The objectives of the petrographic investigation were to estimate thermal maturity, identify organic matter types and abundances, and identify the presence or absence of migrated hydrocarbons. An integrated analytical program included geochemical screening [total organic carbon (TOC) content by LECO, programmed pyrolysis by HAWK, including from solvent-extracted samples], X-ray diffraction mineralogy, organic petrography, SEM-EDS including correlative light...

Rock-eval pyrolysis, vitrinite reflectance, and kerogen microscopy results from Miocene carbonaceous mudstones and coals in outcrop, McGrath Quadrangle, southwestern Alaska
The Cenozoic Holitna basin is a gravity-defined feature that sits astride the Denali-Farewell fault zone in southwestern Alaska. The basin corresponds to a gravity low in excess of -40 milligals (mGals). No outcrops exist within the footprint of the gravity low and no subsurface data are available; consequently, the stratigraphy and age of its fill are unknown. The Alaska Division of Geological & Geophysical Surveys (DGGS) investigated the shallow gas potential of the basin during the summers of 2000 and 2002 by studying Tertiary coal-bearing rocks exposed along the Denali-Farewell fault zone to the northeast of the basin in the southern McGrath Quadrangle as an outcrop analog to the subsurface stratigraphy of the...

Selected geochemistry and mineralogy of Paleozoic strata in northern and central Appalachian basin, U.S.A., 1994-2012
A U.S. Geological Survey (USGS) provisional geochemical and mineralogical database for hydrocarbon-rich shale in the Appalachian region has been compiled by Catherine Enomoto, Frank Dulong and Robert Milici for online distribution. USGS staff collaborated with geologists in State geological agencies to obtain samples that were analyzed for organic properties, including Rock Eval analyses, total organic carbon (TOC), thermal maturity, and semi-quantitative mineralogy. However, the database also contains previously published data, with appropriate citations included. Previously unpublished data are from samples collected and analyzed between 2007 and 2012 from wells drilled between 1931 and 2009, and from exposures...
