- Ocala Limestone Characteristic
residual sediments from the Hawthorn Group lie on the Ocala. The FGS drilling efforts encountered the Ocala Limestone in one hole, FA-A7, at 2.4 feet below land surface. Another hole, FA-A7A, drilled nearby did not encounter the Ocala Limestone. Throughout the area, the top of the Ocala is extremely variable due to karstification and erosion.

The lithology and fossil content of the Ocala Limestone indicates it was deposited across a carbonate platform which covered much of the Florida Peninsula during this time (Salvador, 1991). The Ocala Limestone is a massive, cream–white packstone, with some variation in mud content laterally and vertically, varying from a packstone to wackestone.

However, it is the Ocala Limestone cherts that are of concern here. The Ocala Limestone is composed of upper and lower members (Scott 2001). It was deposited during the Eocene Epoch some 40 to 60 million years ago (Upchurch et al. 1982:13). Lower Ocala Limestone is light colored, granular, and dolomitic with fewer Orbitoid foraminifera.
