Recent and ongoing investigations within the Missourian Stage of eastern Kansas revealed several miscorrelations of bedrock units in the Kansas City and Lansing groups of Miami County, Kansas. These miscorrelations impact several important type and reference sections and highlight the need for additional high-resolution stratigraphic investigation of the Zarah and Linn subgroups within Miami County. This study provides high-resolution chronostratigraphy of these units through the use of detailed cm-scale lithological analyses of 33 drill cores, and conodont biostratigraphy; integrated with geophysical aeromagnetic, aerogravitational, and well-log data. This study also provides one of the first high-resolution δ13Ccarb datasets for the Upper Pennsylvanian providing a foundation for future high-resolution correlation of strata deposited during the Late Paleozoic Ice Age. Chronostratigraphic analyses revealed significant variability within nearshore shales of the upper Linn and Zarah subgroups resulting in moderate thickening and thinning of genetically related units. The thickness variability and distribution of these units is largely controlled by a bathymetric high trending 040° from southwestern Miami County. The stratigraphic resolution of this study improves upon previous investigations and supports the recent revisions to the chronostratigraphic correlations within the Kansas City and Lansing groups.

The recent and rapid growth of horizontal drilling in the Anadarko basin necessitates newer studies to characterize reservoir and source rock quality in the region. Most oil production in the basin comes from the Granite Wash reservoirs, which are composed of stacked tight sandstones and conglomerates that range from Virgillian (305-299 Ma) to Atokan (311-309.4 Ma) in age. By utilizing geophysical well logging data available in raster format, the Granite Wash reservoirs and their respective marine flooding surfaces were stratigraphically mapped across the regional fault systems. Additionally, well log trends were calibrated with coincident core data to minimize uncertainty regarding facies variability and lateral continuity of these intervals. In this thesis, inferred lithofacies were grouped into medium submarine fan lobe, distal fan lobe, and offshore facies (the interpreted depositional environments). By creating isopach and net sand maps in Petra, faulting in the Missourian was determined to have occurred syndepositionally at the fifth order scale of stratigraphic hierarchy.
