Comments on the location information

  • The Southeast Alabama Iron District includes eleven counties: Barbour, Butler, Coffee, Conecuh, Covington, Crenshaw, Dale, Geneva, Henry, Houston, and Pike. The district is bordered by Florida to the south and Georgia to the east. The town of Elba, in Coffee County, is at the approximate center of the district.



    Rail, road, and water transpotation systems traverse the district and provide access to all of the counties. Access would be provided by a network of secondary roads which exist throughout the district, with additional roads developed as neccessary. Eufaula, Alabama, located in Butler County, is on the Chattahoochee River and serves as a river port to the Gulf of Mexico.

Comments on the geologic information

  • The Southeast Alabama District is characterized by southeast-trending sedimentary formations which dip to the southwest at 1.9 to 2.8 meters per kilometer. East of Geneva County, the strike gradually changes to an east-west orientation; average strike is approximately N 85 W. The strike and dip of brown iron ore deposits parallel the local structure.

    Bedrock ranges from Upper Cretaceous to Recent and consists of deeply weathered unconsolidated clay, marl, limestone, calcarious sandstone, and sand. Brown iron ore is found in Paleocene to Oligocene formations, and in residuum of Plaeocene to Miocene. In most instances, the ore zone occurs within the residuum of the Clayton and Porters Creek Formations in the northern half of the district and within residuum of the Moodys Branch, Ocala Limestone, Marianna Limestone, Bryam, and Chickasaw-hay Limestone Formations in the southern half.

    Brown iron ore deposits are scattered through the district and no significant pattern exists. The ore is found within a matrix of sand and clay in lenticular and undulatory zones. Although ore is usually found as a single bed, in some places two ore horizons are separated by a clay or clayey-sand bed. In most cases, ore is overlain by a thin quartzite bed and a clay horizon exists under the ore.

    Brown iron ore exists as an amorphous form of geothite (hydrated iron oxide), commonly termed limonite. The geothite deposits were formed under oxidizing conditions as a weathering product of iron bearing minerals in limestones and marls. These secondary replacement deposits occur most commonly in residuum of the limestones and marls.

    Ore is classified into three types: fine grained or granular, nodular, and fossileferous. The three ore types are usually mixed in one ore zone. Lumps of gray iron carbonate (siderite) are occasionally found in the ore zone.

    Significant or extensive deformation is rare. Small scale faulting and slumping, due primarily to the solution of limestone strata, has created bed displacements of up to 15.2 meters.

General comments

Subject category Comment text
Deposit Brown iron ore deposits in the district are irregular and scattered. Ore zone thickness ranges from 0.3 meters to 6 meters, and averages approximately 1 meter. Overburden ranges from 0.6 meters to 12.2 meters and averages 6 meters.



The approximate areal extent of the deposit is 24,700 hectares for the district, of which approximately 13,500 hectares are in Barbour, Butler, Crenshaw, and Pike Counties. Idealized ore body dimensions are 15,713 meters long by 15,713 meters wide for the district; 11,617 meters by 11,617 meters for Barbour, Butler, Crenshaw, and Pike Counties.
