Bourges
Bourges () is a commune in central France on the river Yèvre. It is the capital of the department of Cher, and also was the capital city of the former province of Berry. History The name of the commune derives either from the Bituriges, the name of the original inhabitants, or from the Germanic word ''Burg'' (French: ''bourg''; Spanish: ''burgo''; English, others: ''burgh'', ''berg'', or ''borough''), for "hill" or "village". The Celts called it ''Avaricon''; Latin-speakers: ''Avaricum''. In the fourth century BC, as in the time of Caesar, the area around it was the center of a Gallic (Celtic) confederacy. In 52 BC, the sixth year of the Gallic Wars, while the Gauls implemented a scorched-earth policy to try to deny Caesar's forces supplies, the inhabitants of Avaricum begged not to have their town burned. It was temporarily spared due to its good defences provided by the surrounding marshes, by a river that nearly encircled it, and by a strong southern wall. Julius Caes ...

Corbières Massif
The Corbières Massif (Catalan: ''Corberes''; french: Massif des Corbières, ) is a mountain range in the Pre-Pyrenees. It is the only true foothill of the Pyrenees on their northern side. Geography The Corbières are a mountain region in the Languedoc-Roussillon in southeastern France, located in the departements of Aude and Pyrénées-Orientales. The river Aude borders the Corbières to the west and north, and the river Agly more or less to the south. The eastern border is the Mediterranean Sea. The eastern part of the Corbières bordering the Mediterranean and the Etangs is also known as the ''Corbières Maritimes'', and has a special kind of climate and typical vegetation (thermo-mediterranean vegetation) which cannot be found in the western part. The highest point of the Corbières is the 1,230 m high Pic de Bugarach.Christophe Neff : ''Les Corbières maritimes – forment-elles un étage de végétation méditerranéenne thermophile masqué par la pression humaine ?''

Maine (province)
Maine () is one of the traditional provinces of France. It corresponds to the former County of Maine, whose capital was also the city of Le Mans. The area, now divided into the departments of Sarthe and Mayenne, counts about 857,000 inhabitants. History Antiquity The Gallic tribe Aulerci Cenomani lived in the region during the Iron Age and Roman period. The province of Maine was named after them, in the 6th century CE as ''in Cinomanico'' (''in'' ''pago Celmanico'' in 765, ''*Cemaine'', then ''Le Maine'' from the 12th century). Early Middle Ages In the 8th and 9th centuries, there existed a Duchy of Cénomannie (ducatus Cenomannicus), which several of the Carolingian kings used as an appanage. This duchy was a march that may have included several counties including Maine, and extended into Lower Normandy, all the way to the Seine. In 748, Pepin the Short, then Mayor of the Palace and thus the most powerful man in Francia after the king, gave this duchy to his half-brother ...

Touraine
Touraine (; ) is one of the traditional provinces of France. Its capital was Tours. During the political reorganization of French territory in 1790, Touraine was divided between the departments of Indre-et-Loire, :Loir-et-Cher, Indre and Vienne. Geography Traversed by the river Loire and its tributaries the Cher, the Indre and the Vienne, Touraine makes up a part of the western Paris Basin. It is well known for its viticulture. The TGV high-speed train system, which connects Tours with Paris (200 kilometers away) in just over an hour, has made Touraine a place of residence for people who work in the French capital but seek a different quality of life. History Touraine takes its name from a Celtic tribe called the Turones, who inhabited the region about two thousand years ago. In 1044, the control of Touraine was given to the Angevins, who (as the House of Plantagenet) became kings of England in 1154, the castle of Chinon being their greatest stronghold. In 1205, Phi ...

Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

Turonian
The Turonian is, in the ICS' geologic timescale, the second age in the Late Cretaceous Epoch, or a stage in the Upper Cretaceous Series. It spans the time between 93.9 ± 0.8 Ma and 89.8 ± 1 Ma (million years ago). The Turonian is preceded by the Cenomanian Stage and underlies the Coniacian Stage. At the beginning of the Turonian an oceanic anoxic event (OAE 2) took place, also referred to as the Cenomanian-Turonian boundary event or the "Bonarelli Event". Stratigraphic definition The Turonian (French: ''Turonien'') was defined by the French paleontologist Alcide d'Orbigny (1802–1857) in 1842. Orbigny named it after the French city of Tours in the region of Touraine (department Indre-et-Loire), which is the original type locality. The base of the Turonian Stage is defined as the place where the ammonite species '' Watinoceras devonense'' first appears in the stratigraphic column. The official reference profile (the GSSP) for the base of the Turonian is located in the Roc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyrénées
The Pyrenees (; es, Pirineos ; french: Pyrénées ; ca, Pirineu ; eu, Pirinioak ; oc, Pirenèus ; an, Pirineus) is a mountain range straddling the border of France and Spain. It extends nearly from its union with the Cantabrian Mountains to Cap de Creus on the Mediterranean Sea, Mediterranean coast. It reaches a maximum altitude of at the peak of Aneto. For the most part, the main crest forms a divide between Spain and France, with the microstate of Andorra sandwiched in between. Historically, the Crown of Aragon and the Kingdom of Navarre extended on both sides of the mountain range. Etymology In Greek mythology, Pyrene (mythology), Pyrene is a princess who eponym, gave her name to the Pyrenees. The Greek historiography, Greek historian Herodotus says Pyrene is the name of a town in Celts, Celtic Europe.

Paris Basin
The Paris Basin is one of the major geological regions of France. It developed since the Triassic over remnant uplands of the Variscan orogeny (Hercynian orogeny). The sedimentary basin, no longer a single drainage basin, is a large sag in the craton, bordered by the Armorican Massif to the west, the Ardennes-Brabant axis to the north, the Massif des Vosges to the east, and the Massif Central to the south.Duval, B.C., 1992, Villeperdue Field, In Giant Oil and Gas Fields of the Decade, 1978-1988, AAPG Memoir 54, Halbouty, M.T., editor, Tulsa: American Association of Petroleum Geologists, Extent The region usually regarded as the Paris Basin is rather smaller than the area formed by the geological structure. The former occupies the centre of the northern half of the country, excluding Eastern France. The latter extends from the hills just south of Calais to Poitiers and from Caen to the brink of the middle Rhine Valley, east of Saarbrücken. Geography The landscape is one of ...

Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now- extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth b ...

Iron Ore
Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (, 72.4% Fe), hematite (, 69.9% Fe), goethite (, 62.9% Fe), limonite (, 55% Fe) or siderite (, 48.2% Fe). Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron-making blast furnaces. Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. In 2011 the ''Financial Times'' quoted Christopher LaFemina, mining analyst at Barclays Capital, saying that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".
