Tuffeau
Tuffeau stone — in French, simply ''tuffeau'' or ''tufeau'' — is a local limestone of the Loire Valley of France. It is characterized as a chalky or sandy, fine-grained limestone, white to yellowish-cream in appearance, and micaceous (containing some white flakes of mica, or muscovite). The soft stone is extracted from numerous quarries and has made a major mark on the architectural landscape of the Loire and its tributaries — especially the valley's world-famous chateaux. Geology Tuffeau dates to the Mesozoic era ( Upper Cretaceous Turonian stage). The Loire Valley formed the floor of a vast sea 90 million years ago. Over the millennia, sediment from the sea floor, comprising fossilized living organisms and sand particles, became compressed to form what is now known as Tuffeau stone. It differs from genuine chalk by the presence of foraminifera and many remains of shells originally deposited in shallow water (between 2 and 20 meters) and subsequently agitated, nea ...

Tufa
Tufa is a variety of limestone formed when carbonate minerals precipitate out of water in unheated rivers or lakes. Geothermally heated hot springs sometimes produce similar (but less porous) carbonate deposits, which are known as travertine. Tufa is sometimes referred to as (meteogene) travertine. It should not be confused with hot spring (thermogene) travertine. Tufa, which is calcareous, should also not be confused with tuff, a porous volcanic rock with a similar etymology that is sometimes also called "tufa". Classification and features Modern and fossil tufa deposits abound with wetland plants; as such, many tufa deposits are characterised by their large macrobiological component, and are highly porous. Tufa forms either in fluvial channels or in lacustrine environments. Ford and Pedley (1996) provide a review of tufa systems worldwide. Fluvial deposits Deposits can be classified by their depositional environment (or otherwise by vegetation or petrographically). P ...

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] |
Building Stone
Building material is material used for construction. Many naturally occurring substances, such as clay, rocks, sand, wood, and even twigs and leaves, have been used to construct buildings. Apart from naturally occurring materials, many man-made products are in use, some more and some less synthetic. The manufacturing of building materials is an established industry in many countries and the use of these materials is typically segmented into specific specialty trades, such as carpentry, insulation, plumbing, and roofing work. They provide the make-up of habitats and structures including homes. The total cost of building materials In history, there are trends in building materials from being natural to becoming more man-made and composite; biodegradable to imperishable; indigenous (local) to being transported globally; repairable to disposable; chosen for increased levels of fire-safety, and improved seismic resistance. These trends tend to increase the ''initial'' and ''l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Château D'Ussé
Ussé is a castle in the Indre-et-Loire ''département'', in France. The stronghold at the edge of the Chinon forest overlooking the Indre Valley was first fortified in the eleventh century by the Norman '' seigneur'' of Ussé, Gueldin de Saumur, who surrounded the fort with a palisade on a high terrace. The site passed to the Comte de Blois, who rebuilt in stone. In the fifteenth century, the ruined castle of Ussé was purchased by Jean V de Bueil, a captain-general of Charles VII who became seigneur of Ussé in 1431 and began rebuilding it in the 1440s; his son Antoine de Bueil married in 1462 Jeanne de Valois, the biological daughter of Charles VII and Agnès Sorel, who brought as dowry 40000 golden écus. Antoine was heavily in debt and in 1455, sold the château to Jacques d’Espinay, son of a chamberlain to the Duke of Brittany and himself chamberlain to the king; Espinay built the chapel, completed by his son Charles in 1612, in which the Flamboyant Gothic style is mixed ...

Saumur
Saumur () is a commune in the Maine-et-Loire department in western France. The town is located between the Loire and Thouet rivers, and is surrounded by the vineyards of Saumur itself, Chinon, Bourgueil, Coteaux du Layon, etc.. Saumur station has rail connections to Tours, Angers, La Roche-sur-Yon and Nantes. Toponymy First attested in the Medieval Latin form of ''Salmuri'' in 968 AD, the origin of the name is obscure. Albert Dauzat hypothesized a pre-Celtic unattested element ''*sala'' 'marshy ground' (''cf.'' Celtic ''salm'' 'which jumps and flows'), followed by another unattested element meaning "wall". Many places in Europe seem to contain ''*Sal(m)-'' elements, which may share Old European roots.

County Of Anjou
The County of Anjou (, ; ; la, Andegavia) was a small French county that was the predecessor to the better-known Duchy of Anjou. Its capital was Angers, and its area was roughly co-extensive with the diocese of Angers. Anjou was bordered by Brittany to the west, Maine to the north, Touraine to the east and Poitou to the south. The adjectival form is Angevin, and inhabitants of Anjou are known as Angevins. In 1360, the county was raised into the Duchy of Anjou within the Kingdom of France. This duchy was later absorbed into the French royal domain in 1482 and remained a province of the kingdom until 1790. Background Anjou's political origin is traced to the ancient Gallic state of the ''Andes''. After the conquest by Julius Caesar, the area was organized around the Roman '' civitas'' of the '' Andecavi''. History Frankish county The Roman civitas was afterward preserved as an administrative district under the Franks with the name first of ''pagus''—then of ''comit ...

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.
