Online_Linkage: https://doi.org/10.14509/30660 Description: Abstract: This data release provides palynomorph assemblages, kerogen observations, thermal maturity estimates, age interpretations, and field station locations of palynology samples collected (2006-2011) from measured stratigraphic sections and key middle Eocene to early Pliocene sedimentary rock outcrops throughout the Kenai, Seldovia, and Tyonek quadrangles. Palynological analysis of surface rock samples offers supporting data for geologic mapping and stratigraphic research conducted by the Alaska Department of Natural Resources' (Alaska Division of Geological & Geophysical Surveys [DGGS] and Alaska Division of Oil & Gas [DOG]) Cook Inlet Basin Analysis Program. The Cook Inlet program provides publicly available baseline outcrop data and geologic findings from the petroleum source, seal, and reservoir rocks of the prospective Cook Inlet hydrocarbon basin. Program products inform interpretations of the geologic processes that shaped the petroleum system's basin evolution. The analytical data tables associated with this report are available in digital format as comma-separated value (CSV) files. Users can access the complete report and digital data from the DGGS website: http://doi.org/10.14509/30660. Purpose: This data release provides palynomorph assemblages, kerogen observations, thermal maturity estimates, age interpretations, and sampling locations of palynology samples. This report and accompanying data supersede a prior release (Zippi and Loveland, 2012) and provide 39 additional analyses from the west side of Cook Inlet. The west Cook Inlet basin palynological age determinations accompany 40Ar/39Ar and zircon U-Pb data presented in Gillis and others (2021).

Laboratory interpretations have been examined in conjunction with geologic mapping and stratigraphic-structural investigations. This report includes a comprehensive review of the field sample numbering, laboratory labels, and sample metadata. Values herein supersede a previous release of a subset of this data (Zippi and Loveland, 2012). Logical_Consistency_Report: not applicable Completeness_Report: This data release is complete. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Location data were collected using handheld recreational grade Garmin GPS units. These devices have a typical reported error of 1-10 m. However, the location accuracy of the sample site coordinates varies according to the sampling context and recording conventions of the observer. A location confidence range, when known, is reported in the data. Locations for samples collected along a measured stratigraphic section reflect the GPS reading at the base of the measured section.

Coal underclays were a common lithology targeted for analysis. When possible, composite samples were collected over a meter or more of the stratigraphic interval, and fresh material was excavated from several centimeters deep to avoid surface contamination. Process_Date: 2011 Process_Step: Process_Description: Sample preparation - Raw outcrop samples were water washed to remove surficial contaminants. Carbonate minerals were dissolved using HCl, and silicate minerals were removed using HF. Heavy liquid separation may have been required if insoluble minerals were present. The organic residue was washed with HNO3, followed by a wash with ammonia or KOH. The residues were sieved through a 7-10 micrometer mesh screen to remove small particles that would be unidentifiable in transmitted light microscopy. Organic residues were mounted on a coverslip with polyvinyl alcohol and fixed to a microscope slide with polyester resin. All samples in this report were processed by Russ Harms of Global Geolab Limited in Medicine Hat, Alberta, Canada. Process_Date: 2011 Process_Step: Process_Description: Palynological analysis - The prepared slides were examined for palynological analysis with a research-grade Zeiss Axio Imager microscope with phase contrast and differential interference contrast illumination using oil immersion objectives at a minimum of 500X. When possible, palynomorph occurrence data were collected until the total count reached 100 specimens for relative abundance data, after which the remaining area of the slide was scanned for rare taxa that may have stratigraphic significance. Rare taxa were added to the count data. The age zones are reported with reference to the palynostratigraphic terminology used in the Cook Inlet Palynology Database of Zippi, 2006, which follows the nomenclature of Wolfe and others (1966). Kerogen residues are typically separated from the palynology residues after demineralization with HCl and HF but before oxidation. For samples that do not require strong oxidation, the kerogen can be described from the lightly oxidized palynology slides. Vitrinite reflectance and maximum temperatures were estimated from pollen/spore color. Dr. Pierre Zippi, Biostratigraphy.com, LLC, performed the palynological, kerogen, and spore color analyses.
