Price's Scrub State Park sits alone within the Fairfield Karst Hills, a small geomorphological subdivision characterized by Hawthorn Formation clays and clayey sands near the surface.
They include the Eocene Ocala Limestone, the Oligocene Suwannee Limestone, the early Miocene Tampa Member of the Arcadia Formation in central Florida and the St. Marks Formation in north Florida, and the middle Miocene Hawthorn Group formations such as the Peace River, Alachua, and Statenville. 3Within these formations are two types of chert.

Ocala Chert is thought to be associated with the Ocala Limestone Formation of the Jackson Group. It is primarily found as nodules and boulders along the bluffs of Flint River, along the crest of low rolling hills in Burke County, Georgia, and in southeastern Alabama. Concentrations are found in Houston and Henry counties, Alabama.
Cooke (1915) continued this formation status but, more importantly, established the Late Eocene age of the Ocala Limestone. Applin and Applin (1944) divided the Ocala Limestone into two units, a Lower and an Upper Member, based on both paleontologic (primarily foraminifera) and lithologic characteristics.
The Ocala Limestone micro-fauna commonly includes Lepidocyclina ocalana, Amphistegina pinarensis, and various Florida Geological Survey miliolids. The top of the Ocala Limestone is identifiable on gamma-ray logs as a sharp decrease in radioactivity relative to the overlying phosphatic Hawthorn Group sediments (Plates 1 and 2).
