Abstract:
Contoured well log data were used to calculate a digital surface representing the top of the Northview Shale, which underlies the Burlington-Keokuk Limestone. Relative topographic highs on the Northview Shale surface lie below several sinkhole clusters within the study area. Lineaments in the Northview Shale surface occur in close proximity to both mapped and undocumented geologic structures such as faults, fault intersections and fold axes. Future geospatial studies incorporating sinkhole geometries, groundwater elevations, and large aperture groundwater conduit locations may build upon the work presented here and provide a better spatial characterization of factors locally controlling the development of the karst features.
