Online_Linkage: https://doi.org/10.14509/31800 Description: Abstract: Rock-Eval pyrolysis, vitrinite reflectance, and kerogen microscopy analytical results from Eocene to Pliocene strata in the Susitna Basin, Kenai Peninsula, and Kachemak Bay, Cook Inlet, Alaska, Raw Data File 2025-31, provides analytical results from Rock-Eval pyrolysis, vitrinite reflectance, and kerogen microscopy performed on 51 outcrop samples collected across the Cook Inlet region, including the Susitna Basin, Kenai Peninsula, and Kachemak Bay. These samples were obtained during DGGS Energy Resources Section field campaigns conducted in 2006, 2007, and 2009 to evaluate regional geology and hydrocarbon potential. Eight samples were analyzed by Rock-Eval pyrolysis, and vitrinite reflectance and kerogen microscopy were completed for the full sample set. The samples represent five stratigraphic units: six from the West Foreland Formation, six from the Hemlock Conglomerate, 18 from the Tyonek Formation, 15 from the Beluga Formation, and six from the Sterling Formation. Rock-Eval pyrolysis supports assessment of hydrocarbon-generative potential and thermal maturity. Vitrinite reflectance and kerogen microscopy provide complementary indicators of organic matter type and thermal evolution. Together, these datasets contribute to a more comprehensive understanding of source rock characteristics and maturation history within the Cook Inlet petroleum system. These data are provided as a Raw Data File under an open end-user license and are available on the DGGS website: http://doi.org/10.14509/31800. Purpose: This data release supports evaluation of source rock quality and thermal maturity in the Cook Inlet region by providing new geochemical and organic petrology analyses. These data strengthen Alaska's regional resource assessments, reduce exploration uncertainty, and inform energy-related decisions that contribute to the state's long-term economic and energy security.

Lineage: Process_Step: Process_Description: Sample collection - DGGS field geologists collected samples from surface outcrops for Rock-Eval pyrolysis, vitrinite reflectance, and kerogen microscopy analyses. Sample location coordinates were obtained using recreational-grade GPS units, with a typical reported accuracy of about 10 meters. Coordinates were collected using the NAD27 datum. Coordinate conversion was performed from NAD27 to NAD83 using ArcGIS Pro. Each sample number corresponds to the measured section number and the sample position (meters above base of section) within each measured section. Coordinates refer to the base of the measured section Process_Date: 2009 Process_Step: Process_Description: Sample analysis - Eight outcrop samples were sent to Weatherford Laboratories in Houston, Texas, for Rock-Eval pyrolysis analysis. The samples analyzed include coal, carbonaceous mudstone, and siltstone. Thirty-two outcrop samples were sent to Baseline Resolution, Inc. in Shenandoah, Texas and 19 to Weatherford Laboratories in Houston, Texas. The labs employed standardized methods for vitrinite reflectance analysis of coal and dispersed vitrinite in sedimentary rocks, following ASTM protocols D2798-11a and D7708-14 (2015). Vitrinite reflectance samples were also evaluated using kerogen microscopy, also known as visual kerogen analysis. Additional details on laboratory methods and data reduction are provided in the accompanying report.
