1. Wikipedia entry for Greenbrier Limestone. The Greenbrier Limestone, also known locally as the “Big Lime,” is an extensive limestone unit deposited during the Middle Mississippian Epoch, part of the Carboniferous Period. This rock stratum is present below ground in much of West Virginia and neighboring Kentucky, and extends somewhat into adjacent western Maryland and southwestern Virginia. The name derives from the Greenbrier River in West Virginia.
Greenbrier Limestone is in some places more than 400 feet (120 metres) thick, allowing it to trap large quantities of oil and gas. Since this carbonate rock erodes quickly in the region's wet climate, outcrops are not prominent and are often quarried.
The Greenbrier Limestone is subdivided into six stratigraphic units. In ascending order, they are Denmar Limestone, Taggard Shale, Pickaway Limestone, Union Limestone, Greenville Shale, and Alderson Limestone. The limestones in this interval are predominantly
Numerous solution caves are developed within the Greenbrier Formation. (Submitted on April 11, 2015.)
2. Wikipedia entry for Oolite (Egg Stone). Oolite (egg stone) is a sedimentary rock formed from ooids, spherical grains composed of concentric layers. The name derives from the ancient Greek word òoion for egg. Strictly, oolites consist of ooids of diameter 0.25–2 mm; rocks composed of ooids larger than 2 mm are called pisolites. The term oolith can refer to oolite or individual ooids. (Submitted on April 11, 2015.)
