Abstract
  • Facies scale heterogeneity was found to be a dominant control on vertical hydraulic conductivity within the carbonate Late Eocene Ocala Formation of the Upper Floridan Aquifer in west-central Florida. Verification of this conclusion was achieved
    by establishing a sedimentary and stratigraphic framework for the Ocala Formation and establishing facies-vertical hydraulic conductivity (K2 ) relationships. This two-fold procedure enabled the construction of a hydrogeologic framework for this unit in west-central Florida. The framework, as first proposed here, suggests that the Ocala Formation is a hydrogeologically heterogeneous carbonate body.

    Logging of seventeen cores and review of more than 300 petrographic thin sections suggest that six wackestone facies , four packstone facies, and two grainstone facies make up the vast majority of Ocala lithologies. Three distinct and mappable
    subdivisions or sequences of the Ocala Formation are recognized in west-central Florida and these appear to be correlatable to other Jackson stage sequences recognized elsewhere in the Gulf of Mexico. The three sequences and their component facies architectures indicate subtidal deposition on a distally steepened carbonate ramp during the Late Eocene.
