Blandas Rigalderie 1
Blandas is a commune in the Gard department in southern France. It is known for its proximity to the Cirque de Navacelles and the town encompasses one of the principal overlooks on the Cirque. It is also known for its exceptional megalithic sites. It is included in the UNESCO world heritage site "The Causses and the Cévennes, Mediterranean agro-pastoral Cultural Landscape" Population History Prehistoric Finds La grotte des Pins In May 1967 a team of speleologists attempted to enlarge a natural opening exposed by erosion. Their work exposed a large hidden room 5m high and on the floor of the room they found fragments of ceramics. Further exploration uncovered tools, objects, and much scattered charcoal, up to 60 cm thick in places possibly from prehistoric torches. Theories at the time suggested that the cave served as a cellar or storage, rather than a habitation, since a lack of air circulation made hearth fires difficult.

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karst
Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German in the late 19th century, which entered German much earlier ...

Plateau
In geology and physical geography, a plateau (; ; ), also called a high plain or a tableland, is an area of a highland consisting of flat terrain that is raised sharply above the surrounding area on at least one side. Often one or more sides have deep hills or escarpments. Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, and erosion by water and glaciers. Plateaus are classified according to their surrounding environment as intermontane, piedmont, or continental. A few plateaus may have a small flat top while others have wide ones. Formation Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, Plate tectonics movements and erosion by water and glaciers. Volcanic Volcanic plateaus are produced by volcanic activity. The Columbia Plateau in the north-western United States is an example. They may be formed by upwelling of volcanic magma or extrusion of lava. The un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Massif Central
The (; oc, Massís Central, ; literally ''"Central Massif"'') is a highland region in south-central France, consisting of mountains and plateaus. It covers about 15% of mainland France. Subject to volcanism that has subsided in the last 10,000 years, these central mountains are separated from the Alps by a deep north–south cleft created by the Rhône river and known in French as the ' (literally "Rhône furrow"). The region was a barrier to transport within France until the opening of the A75 motorway, which not only made north–south travel easier, but also opened access to the massif itself. Geography and geology The is an old massif, formed during the Variscan orogeny, consisting mostly of granitic and metamorphic rocks. It was powerfully raised and made to look geologically younger in the eastern section by the uplift of the Alps during the Paleogene period and in the southern section by the uplift of the Pyrenees. The massif thus presents a strongly asymmet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Causses
The Causses () are a group of limestone plateaus (700–1,200 m) in the Massif Central. They are bordered to the north-west by the Limousin and the Périgord uplands, and to the east by the Aubrac and the Cévennes. Large river gorges cut through the plateau, such as the Tarn, Dourbie, Jonte, Lot and Aveyron. ''Causse'' is an Occitan word meaning "limestone plateau". The Causses and the Cévennes, Mediterranean agro-pastoral Cultural Landscape was added to the UNESCO World Heritage list in 2011, because of the region's extensive and continuous use of Mediterranean pastoral systems and their testimony to the traditional methods of transhumance. Since at least the Bronze Age, the Causses were used for sheep and cattle droving, and in the Middle Ages, religious orders established in the area, building irrigation and road networks that are still used by farmers today. Characteristics of the region are large farm complexes made out of limestone and long, low stone buildings (often mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
