Kaolin is one of the many industrial minerals mined in Georgia today. The commercially mineable kaolin deposits are found in a relatively narrow "belt" along the Fall Line. The kaolin mining industry has located its processing facilities in the communities near the deposits, primarily in the nine rural counties between Macon and Augusta.

Kaolinite. The most fundamental clay mineral. This mineral is found in nature in its purest form as kaolin.However it makes up at least part of all ceramic clays. The purest deposits are created as it is weathered from rock and deposited, mixed with other products of the weathering process, in layers and lenses in nearby valleys.
Six types of clays are mined in the United States: ball clay, bentonite, common clay, fire clay, fuller's earth, and kaolin. Mineral composition, plasticity, color, absorption qualities, firing characteristics, and clarification properties are a few of the characteristics used to distinguish between the different clay types. Major domestic markets for these clays are as
Kaolin. During the weathering of intrusive rocks a process known as "kaolinization" occurs wherein the sodium feldspar breaks down into kaolin group minerals – kaolinite and halloysite. Both are hydrated aluminosilicate minerals. Kaolinite (Al 2 Si 2 O 5 (OH) 4 ) occurs as plate-like sheets that commonly appear as "stacked books".
Kaolinite is an important mineral constituent of many clastic sediments, especially, clay, sand, and pelite sediments, marl, and clay (Sections 6.5.3 and 6.5.4 Section 6.5.3 Section 6.5.4).
