We use the integration of gravity, magnetic, and 3-dimensional (3-D) seismic data to map sedimentary features and study the relationships between sedimentary and basement features in the Osage County area of northeast Oklahoma. The prominent gravity and magnetic anomaly studied within this region are related to the mid-continent rift system. However, we cannot substantiate this conclusion with geochronological age-dating data at this time. Prominent dipping Precambrian reflectors seen on seismic section suggest that extension occurred before emplacement of shallow basement. A regional episode of extension possibly occurred early in the development of the 1400 to 1340 Ma magmatic province. Thus, we interpret the structure we see to be a basin that might have formed during this interval. We use volumetric seismic attributes such as coherence and curvature derived from seismic data to better characterize subtle features such as collapse features and faulting and fracturing within the Mississippian and Ordovician carbonate deposits that are difficult to detect on conventional 3-D seismic data displays. Blended seismic images of these carbonate reservoirs reveal polygonal, highly coherent, and high-amplitude lineaments, which trend northeast and northwest. The northeast-striking lineaments are related to the late Paleozoic Nemaha tectonics, whereas the northwest lineaments are interpreted to be related to the inherent basement fabric or the draping of the Mississippian over a cockpit karst terrain. Although a one-to-one correlation between the basement structures and the carbonate reservoirs cannot be established, basement structure lineaments are parallel in orientation to those seen within the Mississippian chert and the Arbuckle Group.
