Limagne
The Limagne (; ) is a large plain in the Auvergne, Auvergne region of France in the valley of the Allier (river), Allier river, on the edge of the Massif Central. It mainly lies within the ''departments of France, départements'' of Puy-de-Dôme, Allier and Haute-Loire. The term is sometimes used to include this, and three other less extensive plains, that lie along the valley of the Allier, in which case the first is known as ''Grande Limagne'' to distinguish it from the others. The name is derived from the Latin ''Lacus Magnus'', or large lake. Geology The Limagne plain is a graben, downthrown from the Massif Central by a series of Fault (geology)#Dip-slip faults, normal faults that border the western edge of the plain. It contains about 2 km of sediments, and the amount of stretching of the Crust (geology), crust is estimated as 1.2–1.3. The rifting started in the Late Eocene and the main phase of subsidence continued into the Late Oligocene. The Limagne Graben forms par ...

European Cenozoic Rift System
The European Cenozoic Rift System (ECRIS) is a long system of rifts formed in the foreland of the Alps as the lithosphere responded to the effects of the Alpine and Pyrenean orogenies. The system began to form during the Late Eocene and parts (particularly the Upper and Lower Rhine Grabens) remain seismically active today and are responsible for most of the larger earthquakes in Europe, north of the Alps. Extent The ECRIS consists of a series of rifts and associated transfer faults extending from the Mediterranean to the North Sea. Limagne Graben This north-south trending rift structure formed in the middle Eocene creating a lake that is now the Limagne plain. The main phase of subsidence continued until the Late Oligocene. The graben is controlled by faults on its western side and is filled with Cenozoic sediments up to 2 km thick. Bresse Graben The Bresse Graben lies to the east of the Limagne Graben. Rifting started during the Eocene, pausing from the Late Oligoce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Peperite
A peperite is a type of volcaniclastic rock consisting of sedimentary rock that contains fragments of younger igneous material and is formed when magma comes into contact with wet sediments. The term was originally used to describe rocks from the Limagne region of France, from the similarity in appearance of the granules of dark basalt in the light-coloured limestone to black pepper. Typically the igneous fragments are glassy and show chilled-margins to the sedimentary matrix, distinguishing them from clasts with a sedimentary origin. Terminology The term has been used to describe a wide variety of rocks that are interpreted to have formed by the interaction between magma and sediments. This usage has led to overlap with other terms such as hyaloclastite. In the 2002 edition of ''"Igneous Rocks"'' by Le Maître et al., the definition is given as "A local term for a tuff or breccia, formed by the intrusion of magma into wet sediments. Usually consists of glassy fragments of igneou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alpine Orogeny
The Alpine orogeny, sometimes referred to as the Alpide orogeny, is an orogenic phase in the Late Mesozoic and the current Cenozoic which has formed the mountain ranges of the Alpide belt. Cause The Alpine orogeny was caused by the African continent, the Arabian Peninsula, the Indian subcontinent, and the Cimmerian plate colliding with Eurasia in the north. Convergent movements between the African, Arabian and Indian plates from the south, and the Eurasian plate and the Anatolian sub-plate from the north – as well as many smaller (micro)plates – had already begun during the early Cretaceous, but the major phases of mountain building began during the Paleocene to the Eocene. The process continues currently in some of the Alpide mountain ranges. The Alpine orogeny is considered one of the three major phases of orogeny in Europe that define the geology of that continent, along with the Caledonian orogeny that formed the Old Red Sandstone Continent when the continents ...

Middle Ages
In the history of Europe, the Middle Ages or medieval period lasted approximately from the 5th to the late 15th centuries, similarly to the post-classical period of global history. It began with the fall of the Western Roman Empire and transitioned into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages. Population decline, counterurbanisation, the collapse of centralised authority, invasions, and mass migrations of tribes, which had begun in late antiquity, continued into the Early Middle Ages. The large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the 7th century, North Africa and the Middle East—once part of the Byzantine Empire� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Corent
Corent () is a commune in the Puy-de-Dôme department in Auvergne-Rhône-Alpes in central France. It sits approximately 2 miles north of Les Martres-de-Veyre on the side of the old volcanic Puy de Corent. In 2001 excavation began on a Gallic (Celtic) and later Gallo-Roman Oppidum found in a field atop the puy. To this date, vast quantities of land have been excavated revealing the site as a main political, religious and economic center. Corent was an important fortified Celtic oppidum during the pre-Roman La Tène period (Late Iron Age), and there was already a dense fortified/walled settlement on the plateau during the Late Bronze Age Urnfield period.

Vineyard
A vineyard ( , ) is a plantation of grape-bearing vines. Many vineyards exist for winemaking; others for the production of raisins, table grapes, and non-alcoholic grape juice. The science, practice and study of vineyard production is known as viticulture. Vineyards are often characterised by their , a French term loosely translating as "a sense of place" that refers to the specific geographical and geological characteristics of grapevine plantations, which may be imparted to the wine itself. History The earliest evidence of wine production dates from between 6000 and 5000 BC. Wine making technology improved considerably with the ancient Greeks but it was not until the end of the Roman Empire that cultivation techniques as we know them were common throughout Europe. In medieval Europe the Catholic Church was a staunch supporter of wine, which was necessary for the celebration of the Mass (liturgy), Mass. During the lengthy instability of the Middle Ages, the monasteries m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sugar Beet
A sugar beet is a plant whose root contains a high concentration of sucrose and that is grown commercially for sugar production. In plant breeding, it is known as the Altissima cultivar group of the common beet (''Beta vulgaris''). Together with other beet cultivars, such as beetroot and chard, it belongs to the subspecies ''Beta vulgaris'' subsp. ''vulgaris'' but classified as ''var. saccharifera''. Its closest wild relative is the sea beet (''Beta vulgaris'' subsp. ''maritima''). Sugar beets are grown in climates that are too cold for sugarcane. In 2020, Russia, the United States, Germany, France and Turkey were the world's five largest sugar beet producers. In 2010–2011, Europe, and North America except Arctic territories failed to supply the overall domestic demand for sugar and were all net importers of sugar. The US harvested of sugar beets in 2008. In 2009, sugar beets accounted for 20% of the world's sugar production and nearly 30% by 2013. Sugarcane accounts for most ...

Limestone
Limestone is a type of carbonate rock, carbonate sedimentary rock which is the main source of the material Lime (material), lime. It is composed mostly of the minerals calcite and aragonite, which are different Polymorphism (materials science), crystal forms of calcium carbonate . Limestone forms when these minerals Precipitation (chemistry), 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 (rock), dolomite, a closely related rock, which contains a high percentage of the mineral Dolomite (mine ...

Lake
A lake is often a naturally occurring, relatively large and fixed body of water on or near the Earth's surface. It is localized in a basin or interconnected basins surrounded by dry land. Lakes lie completely on land and are separate from the ocean, although they may be connected with the ocean by rivers. Lakes, as with other bodies of water, are part of the water cycle, the processes by which water moves around the Earth. Most lakes are fresh water and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater. Lakes vary significantly in surface area and volume of water. Lakes are typically larger and deeper than ponds, which are also water-filled basins on land, although there are no official definitions or scientific criteria distinguishing the two. Lakes are also distinct from lagoons, which are generally shallow tidal pools dammed by sandbars or other material at coastal regions of ocean ...
