Bridgeboro Limestone is a rhodolith limestone that occurs on the northern and southern flanks of the Gulf Trough and crops out discontinuously in a NE-SW band from south-central GA to northwest FL, a distance of 290 km. Assignment of the Bridgeboro Limestone to the Vicksburgian Stage (lower Oligocene) is substantiated by the occurrence of the bivalves CHLAMYS (ANATIPOPECTEN) …
The Ocala Limestone of late Eocene age over lies the Lisbon Formation and occurs at from about 70 to 350 feet below land surface. It is a cream to brown, rather pure limestone and sup plies 90 to 95 percent of the water pumped from the city wells. Alluvium and residuum deposits of Eocene to
Geological characteristics at JERC are typical of Ocala Limestone. [28] Soils. The Jones Center is located on a karst topography called the Dougherty Plain. The soil parent materials are dominantly sandy coastal plain deposits that include clay lenses. Thus soils range from sandy to coarse loamy to clay-like.
Pg. C51-C56. Tivola tongue of Ocala limestone. A bed of bryozoan-bearing limestone typically exposed at quarry of Planters Limestone Company, 2 mi south of Tivola, Houston County, central Georgia, which projects as far north as Rich Hill, Crawford County, and intrudes far into the main area of the contemporaneous Barnwell formation in which it forms an important horizon marker near …
The Ocala is a wedge shaped limestone formation trending from northeast to southwest across Georgia, thickening to the southeast. The Ocala varies in thickness from a few feet at the updip limitto 350 feet in the southeastern part of the Dougherty Plain {fig. 3) The upper surface of the Ocala Limestone is highly
The Albany West Quadrangle is near the east edge of the Dougherty Plain of southwestern Georgia, an area of karst topography. The Ocala limestone (uppoer Eocene) underlies the quadrangle and crops out along the Flint River and its tributaries and sinkholes. Sinkholes of two ages are developed in the limestone. A gravelly argillaceous sand of Pliocene(?) age is exposed in ditches near the Flint ...
The Ocala Limestone of Florida, Georgia, and Alabama is widely exposed in many parts of these states. It con-tains an abundant, diverse, and well-preserved echinoid fauna. During the Late Eocene deposition of the unit, it was the site of intermixing between dis-tinctive Gulf Coast and Caribbean fau-nas. Thus, Ocala deposits offer a unique
Description. Suwannee Limestone is found in the peninsula carbonate outcroppings on the northwestern, northeastern and southwestern flanks of the Ocala Platform.However, Suwannee Limestone is not present on an area known as Orange Island on the eastern side of the Ocala Platform due to erosion, nondeposition or both. This limestone is present in southeastern Leon, Jefferson, Madison, Taylor ...
Information obtained from a study of well samples indicates that limestones of Eocene age in peninsular Florida have a thickness of more than three thousand feet. At the time these limestones were being laid down the sea covered most, if not all, of what is now Florida as well as the southern portions of the adjacent states of Georgia and Alabama. During this period there were most likely ...
The aquifer includes units of sand, clay, limestone, and dolomite of middle Eocene age and younger, that form, in ascending order, the Lisbon Formation, the Clinchfield Sand, the Ocala Limestone, and the Suwannee Limestone. The aquifer is overlain by undifferentiated sediments of Miocene age and undifferentiated overburden of Quaternary age.
This area is one of the most productive artesian areas in the United States. The wells yield, by flow or pumping, at least 180 million gallons a day, of which six industrial plants use more than 80 million gallons a day; the remainder is used for many different industrial, public, and domestic supplies, or is discharged from flowing wells without being used.The Eocene Ocala limestone is the ...
The Ocala Limestone in the Dougherty Plain region of southwest Georgia is a fine-grained, white or cream-colored, fossil-bearing limestone. It is believed to have formed in the quiet, open waters of the continental shelf far from land.
The (Upper Jacksonian) Crystal River Limestone occurs south of the Gulf Trough in southwestern and central Georgia and is continuous into central Florida, the type area of the Ocala Limestone. In eastern coastal Georgia and northeastern coastal Florida, the Crystal River grades eastward into an unnamed bryozoan limestone that is mostly a ...
only from the Ocala Limestone, but most of them obtain water from the Ocala and Suwannee Limestones and the Tallahatta Formation. Yields of as much as 1,000 gpm may be obtained from properly construc ted wells in the Ocala Limestone or Tallahatta Formation near the northwestern border of …
The Ocala Limestone ranges in thickness from about 107 to 152 m in the Valdosta area. The Suwannee Limestone ranges in thickness between 61 and 76 m. The upper water-bearing zone of the Upper Floridan aquifer ranges in thickness from 85 m in the central part of the Valdosta study area to less than 76 m near the northern and southern boundaries ...
Ocala Limestone (Eocene) at surface, covers 3 % of this area. Generally covered with Oligocene and Eocene residuum (Flint River Formation of Cooke, 1939); includes up-dip area, Tivola Limestone of Connell (1955). (*)- outcrops of Ocala Limestone on Dougherty Plain.
University of Georgia Atbeao, GA 30602 ABSTRACT Analysis of fractu~~ trace and sinkhole characteristics near 33 wells drawing water from the Ocala Limestone aquifer beneath the Dougherty Plain of southwes~ Georgia, reVealed that the distance (rom a we]) to the closest fracture trace (DISTL) explained 67% of the variation in well productivities.
stone and becomes part of the Ocala Limestone. LITHOLOGY Figure 2 shows the section that exists below the limestone floor of the west quarry of the Penn-Dixie Cement Co., near Clinchfield, Ga. Here, the Ocala Limestone rests directly upon fine-grained Clinch- field Sand, which in turn overlies the Lisbon Formation (equivalent
Fracturing and dissolution of the Ocala Limestone formation in southwestern Georgia, USA, have resulted in mature karstic development and a high-yielding aquifer; the Upper Floridan. This aquifer, which supplies many millions of gallons of water per day for irrigated agriculture, is hydraulically connected to many streams throughout the lower Flint River Basin.

The Ocala limestone of the Jackson group is exposed in the valley of the Flint River and along Muckalee and Kinchafoonee Creeks. The Ocala ranges in thick ness from 70 feet in western Dougherty County to 250 feet in the eastern part. It is a pure limestone, containing as much as 98 percent calcium carbonate.
Pg. 56. Ocala limestone. Ocala transgresses beveled surface of Avon Park, Tallahassee, and Lake City limestones. Top of Ocala was land surface before younger marine deposits were laid down. Ocala is overlain by Marianna limestone, Byram limestone, and Suwannee limestone, or Hawthorn formation. [Age is late Eocene.]
Also in the Ocala Group is the more recent and distinct Ocmulgee Formation. While the Ocala Limestone certainly occurs in Southwest Georgia and Florida, the Houston County limestone Pickering referred to as the Ocala is separate and distinct from the Ocala of SW Georgia and Florida.

ered limestone of Eocene and Oligocene age is located at or near land surface. The late Eocene Ocala Limestone extends throughout the 6,800-square-mile area of the lower Apalachicola-Chattahoochee-Flint River Basin from the outcrop area along the northwestern boundary of the Dougherty Plain (Fig. 1) southeastward beneath the dam.
Georgia geologic units Ocala Limestone (Eocene) at surface, covers 78 % of this area Generally covered with Oligocene and Eocene residuum (Flint River Formation of Cooke, 1939); includes up-dip area, Tivola Limestone of Connell (1955).
The Ocala Limestone, Kellogg and Cooke report that the fossils came from the upper Jackson Formation means that they are between 33.9 to 35.2 million years old. They also refer to the sediments as the Ocala Limestone. The Ocala Limestone was named in 1892 by Dall and Harris and can be found in much of Florida. (11,Pg.23)
Ground water in the Albany area is obtained from four aquifers of Late Cretaceous to middle Tertiary age that range in depth from about 40 to 960 feet below land surface. From deepest to shallowest the aquifers are: the Providence (sand), the Clayton (limestone), the Tallahatta (sand), and the Ocala (limestone).
