What minerals are in the coastal plains region in Georgia?

Answer 1

Metallic Mineral DepositsAlthough not mined commercially, numerous concentrations of heavy mineral sands have been identified in ancient river and beach deposits along the western margin of the Coastal Plain and offshore on the continental shelf. Deposits of rutile, ilmenite, monazite, zircon (ZrSiO4), and gold have been investigated in North and South Carolina. Although minor production has occurred in the past, these deposits are currently considered not economical to mine, occur in environmentally sensitive or urban areas. Non-Metallic Mineral DepositsA residual product of weathering in the Cretaceous carbonate rocks is bauxite. Bauxite is a clay-like mixture of several minerals, but dominantly gibbsite (Al(OH)3). Mined primarily as an ore of aluminum, most bauxite ore contains 45-55% Al2O3. Bauxite deposits are found in Georgia, Alabama, Tennessee, and Virginia. Small scale production has continued in Alabama to the present. Southeast bauxite deposits are generally small and of limited potential.

Phosphate is present in Coastal Plain sediment ranging in age from the mid-Tertiary through the Quaternary, and extends along the Atlantic coast from the Chesapeake Bay to Florida. The highest grade and most extensive deposits occur in the Miocene formations of North Carolina and Florida, which together account for about 95% of domestic production of phosphate and about half of global production. Phosphates are used primarily to make fertilizers, but are also used in the manufacture of phosphoric acid, detergents, food additives, pesticides, soft drinks, and other products.
