Lascaux Cave
Lascaux ( , ; french: Grotte de Lascaux , "Lascaux Cave") is a network of caves near the village of Montignac, in the department of Dordogne in southwestern France. Over 600 parietal wall paintings cover the interior walls and ceilings of the cave. The paintings represent primarily large animals, typical local contemporary fauna that correspond with the fossil record of the Upper Paleolithic in the area. They are the combined effort of many generations and, with continued debate, the age of the paintings is now usually estimated at around 17,000 years (early Magdalenian). Because of the outstanding prehistoric art in the cave, Lascaux was inducted into the UNESCO World Heritage List in 1979, as an element of the ''Prehistoric Sites and Decorated Caves of the Vézère Valley''. The original caves have been closed to the public since 1963, as their condition was deteriorating, but there are now a number of replicas.

Prehistoric Sites And Decorated Caves Of The Vézère Valley
The Prehistoric Sites and Decorated Caves of the Vézère Valley is a UNESCO World Heritage Site in France since 1979. It specifically lists 15 prehistoric sites in the Vézère valley in the Dordogne department, mostly in and around Les Eyzies-de-Tayac-Sireuil, which has been called the "Capital of Prehistory". This valley is exceptionally rich in prehistoric sites, with more than 150 known sites including 25 decorated caves, and has played an essential role in the study of the Paleolithic era and its art. Three of the sites are the namesakes for prehistoric periods; the Micoquien (named after La Micoque), Mousterian (after Le Moustier), and Magdalenian (after Abri de la Madeleine). Furthermore, the Cro-Magnon rock shelter gave its name to the Cro-Magnon, the generic name for the European early modern humans. Many of the sites were discovered or first recognised as significant and scientifically explored by the archaeologists Henri Breuil and Denis Peyrony in the early twe ...

Carbon Dioxide
Carbon dioxide ( chemical formula ) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. It is a trace gas in Earth's atmosphere at 421 parts per million (ppm), or about 0.04% by volume (as of May 2022), having risen from pre-industrial levels of 280 ppm. Burning fossil fuels is the primary cause of these increased CO2 concentrations and also the primary cause of climate change.IPCC (2022Summary for policy makersiClimate Change 2022: Mitigation of Climate Change.

Dordogne (river)
The Dordogne (; oc, Dordonha) is a river in south-central and southwest France. It is long. The Dordogne and its watershed were designated Biosphere Reserve by UNESCO on July 11 2012. Geography The river rises on the flanks of the Puy de Sancy at above sea level in the mountains of Auvergne, from the confluence of two small torrents above the town of Le Mont-Dore: the ''Dore'' and the ''Dogne''. It flows generally west about through the Limousin and Périgord regions before flowing into the Gironde, its common estuary with the Garonne, at the Bec d'Ambès ("Ambès beak"), north of the city of Bordeaux. Nature The Dordogne is one of the few rivers in the world that exhibit the phenomenon of a tidal bore, known as a mascaret. The upper valley of the Dordogne is a series of deep gorges. The cliffs, steep banks, fast flowing water and high bridges attract both walkers and drivers. In several places the river is dammed to form long, deep lakes. Camp sites and holiday homes ...

Périgord
Périgord ( , ; ; oc, Peiregòrd / ) is a natural region and former province of France, which corresponds roughly to the current Dordogne department, now forming the northern part of the administrative region of Nouvelle-Aquitaine. It is divided into four areas called the Périgord Noir (Black), named so for the truffles that can be found there, the Périgord Blanc (White), for chalk cliffs and quarries, the Périgord Vert (Green), for forests and forestry and the Périgord Pourpre (Purple), for wine and viticulture . The geography and natural resources of Périgord make it a region rich in history and wildlife, and the newly created Parc Naturel Régional Périgord-Limousin aims to conserve it as such. Périgord is noted for its cuisine, especially its duck and goose products, such as ''confit de canard'' and ''foie gras''. It is known as a centre for truffles in France. Périgourdine wines include Bergerac (red and white) and Monbazillac. Geography Périgord surrounds ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vézère
The Vézère (; oc, Vesera) is a 211-km-long river in southwestern France. It is an important tributary to the Dordogne. Its source is in the northwestern part of the elevated plateau known as the Massif Central. It flows into the Dordogne near Le Bugue. A tributary of the Vézère is the Corrèze. The Vézère Valley is famed for its prehistoric cave systems, containing numerous cave paintings and hominid remains. UNESCO collectively designated these a World Heritage Site in 1979. Among the sites with remarkable caves is Lascaux. Geography The Vézère takes its source in the bog of Longéroux, on the plateau of Millevaches, in the Massif Central in Corrèze, at 887 meters above sea level, in the commune of Meymac, west of the ''Puy Pendu'' (973 m) in the forest of Longéroux, at the place called ''sources de la Vézère''. It flows into the Dordogne on the right bank at Limeuil, at an altitude of 50 metres. Its main tributary is the Corrèze, their confluence is located in th ...

Facsimile
A facsimile (from Latin ''fac simile'', "to make alike") is a copy or reproduction of an old book, manuscript, map, art print, or other item of historical value that is as true to the original source as possible. It differs from other forms of reproduction by attempting to replicate the source as accurately as possible in scale, color, condition, and other material qualities. For books and manuscripts, this also entails a complete copy of all pages; hence, an incomplete copy is a "partial facsimile". Facsimiles are sometimes used by scholars to research a source that they do not have access to otherwise, and by museums and archives for media preservation and conservation. Many are sold commercially, often accompanied by a volume of commentary. They may be produced in limited editions, typically of 500–2,000 copies, and cost the equivalent of a few thousand United States dollars. The term " fax" is a shortened form of "facsimile" though most faxes are not reproductions of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ochre
Ochre ( ; , ), or ocher in American English, is a natural clay earth pigment, a mixture of ferric oxide and varying amounts of clay and sand. It ranges in colour from yellow to deep orange or brown. It is also the name of the colours produced by this pigment, especially a light brownish-yellow. A variant of ochre containing a large amount of hematite, or dehydrated iron oxide, has a reddish tint known as "red ochre" (or, in some dialects, ruddle). The word ochre also describes clays coloured with iron oxide derived during the extraction of tin and copper. Earth pigments Ochre is a family of earth pigments, which includes yellow ochre, red ochre, purple ochre, sienna, and umber. The major ingredient of all the ochres is iron(III) oxide-hydroxide, known as limonite, which gives them a yellow colour. * Yellow ochre, , is a hydrated iron hydroxide (limonite) also called gold ochre. * Red ochre, , takes its reddish colour from the mineral hematite, which is an anhydrous i ...

Charcoal
Charcoal is a lightweight black carbon residue produced by strongly heating wood (or other animal and plant materials) in minimal oxygen to remove all water and volatile constituents. In the traditional version of this pyrolysis process, called charcoal burning, often by forming a charcoal kiln, the heat is supplied by burning part of the starting material itself, with a limited supply of oxygen. The material can also be heated in a closed retort. Modern "charcoal" briquettes used for outdoor cooking may contain many other additives, e.g. coal. This process happens naturally when combustion is incomplete, and is sometimes used in radiocarbon dating. It also happens inadvertently while burning wood, as in a fireplace or wood stove. The visible flame in these is due to combustion of the volatile gases exuded as the wood turns into charcoal. The soot and smoke commonly given off by wood fires result from incomplete combustion of those volatiles. Charcoal burns at a highe ...

Iron Oxide
Iron oxides are chemical compounds composed of iron and oxygen. Several iron oxides are recognized. All are black magnetic solids. Often they are non-stoichiometric. Oxyhydroxides are a related class of compounds, perhaps the best known of which is rust. Iron oxides and oxyhydroxides are widespread in nature and play an important role in many geological and biological processes. They are used as iron ores, pigments, catalysts, and in thermite, and occur in hemoglobin. Iron oxides are inexpensive and durable pigments in paints, coatings and colored concretes. Colors commonly available are in the "earthy" end of the yellow/orange/red/brown/black range. When used as a food coloring, it has E number E172. Stoichiometries Iron oxides feature as ferrous ( Fe(II)) or ferric (Fe(III)) or both. They adopt octahedral or tetrahedral coordination geometry. Only a few oxides are significant at the earth's surface, particularly wüstite, magnetite, and hematite. * Oxides of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
