Greenbrier Group (original) (raw)
The Greenbrier Limestone, also known locally as the "Big Lime", is an extensive limestone unit deposited during the Middle Mississippian Epoch (345.3 ± 2.1 – 326.4 ± 1.6 Ma), 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. Numerous solution caves are developed within the Greenbrier Formation.

| dbo:abstract | The Greenbrier Limestone, also known locally as the "Big Lime", is an extensive limestone unit deposited during the Middle Mississippian Epoch (345.3 ± 2.1 – 326.4 ± 1.6 Ma), 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 , , , , , and . The limestones in this interval are predominantly skeletal grainstones or packstones. The Pickaway and especially the Union contain oolitic grainstones. Numerous solution caves are developed within the Greenbrier Formation. (en) Le calcaire de Greenbrier (en anglais Greenbrier Limestone, connu localement sous le nom de Big Lime) est une formation calcaire, qui s'est déposée pendant le Viséen (ou Mississippien moyen, 345.3 ± 2.1 – 326.4 ± 1.6 Ma) et qui s'étend sur toute la Virginie-Occidentale, le Kentucky, l'ouest du Maryland et le sud-ouest de la Virginie. Il est ainsi nommé en référence à la rivière . La couche a par endroits plus de 120 mètres d'épaisseur et contient des gisements de pétrole et de gaz. Le calcaire de Greenbrier est divisé en six unités stratigraphiques, qui sont, dans un ordre ascendant : le calcaire de Denmar ; le schiste de Taggard ; le calcaire de Pickaway ; le calcaire de l'Union ; le schiste de Greenville et le calcaire d'Alderson. En Virginie-Occidentale, le calcaire comporte de nombreuses grottes. * Portail de la géologie * Portail des États-Unis (fr) |
