Geology of Georgia
|
GEOLOGY OF GEORGIA The State of Georgia is commonly divided into geological regions. The Valley and Ridge, the Blue Ridge, the Piedmont, and the Coastal Plain regions are based on the changes in rock types. The Valley & Ridge- The Eastern and Southern boundary of the Valley and Ridge is the Cartersville-Great Valley Fault system, which runs South from Chatsworth to a point Southeast of Cartersville and then West to the Polk-Haralson County Line. The Blue Ridge- One of the most commonly accepted boundaries would run just southeast of Canton, Dawsonville, Dahlonega, and Helen. The Piedmont- The Piedmont runs SW - NE and passes through Centralhatchee in Heard County, Northwest Atlanta, Duluth, Buford, and Gainesville. The Chattahoochee River follows the Brevard Zone too. The Coastal Plain- The Coastal Plain is the Southern or Southeastern half of Georgia, and Americus, Albany, Valdosta, Waycross, and Savannah are all Coastal Plain Cities. Sandstone from Lookout Mountain, Granite from Stone Mountain, and Quartzites with Lazulite Crystals from Graves Mountain is on display from the Geology Department of CSU.

The Fall Line
|
The Fall Line: Geology's Impact on Town Formation The Fall Line is the boundary between the Piedmont and the Coastal Plain. Since the river has a rapid fall near Columbus, industrialists quickly gauged the untamed power of the river and began to make plans to harness it for economic benefit. Grist mills, textile mills, and other manufacturing concerns took advantage of the river to power their machinery, turning Columbus into one of the few centers of industry in the South before the Civil War.

History
|
Geological History of Georgia During the Pennsylvania Period and the Cretaceous Period, Georgia was covered by water. This may be the reason that so many shark teeth fossils are found. Due to the large amount of shark teeth found, the Shark Tooth was chosen as Georgia's State Fossil. On loan from the Geology Department of CSU are a Large Shark Tooth Cast Carcharodon megalodon, a Trilobite Elrathia antiquata, and some Small Shark Teeth Scapanorhynchus texanus. Visit the display near the entrance to the library to see these exciting specimens. |
Mining
|
Minerals Mined in Georgia Historically mined Minerals are Gold, Bauxite, Hematite & Goethite, Pyrolusite, Beryl, Pyrite, Kyanite, Corundum, Garnet, Talc, and Anthophyllite. Currently mined Minerals are Kaolin, Barite, Ochre, Granite, Marble, Feldspar, Muscovite, Fullers Earth, and Limestone. Mineral samples, borrowed from the Geology Department of CSU, Kaolin, Barite, Ochre, Marble, Limestone, Mica, Staurolite, and Feldspar are on display. |

All minerals and fossils seen in the Geology of Georgia Display and Webpage were on loan from Dr. Schwimmer and Dr. Hanley of the Columbus State University Geology Department. This display could not have been accomplished without their generosity. |
