Abstract
Understanding the geologic controls of porosity development and their relationship to the karst aquifer system in the Cambrian Maynardville Limestone is important in determining possible contaminant transport pathways and provides essential data for hydrologic models within the Oak Ridge Reservation of east Tennessee. In the Maynardville Limestone, several important factors control porosity development: (1) lithologic controls on secondary microporosity and mesoporosity are related to dissolution of evaporite minerals and dedolomitization in supratidal facies; (2) depth below the ground surface controls the formation of karst features because the most active portion of the groundwater system is at shallow depths, and karst features are rare below ≈35 m; and (3) structural controls are related to solution enlargement of fractures and faults.
