La Bazouge-de-Chemeré
La Bazouge-de-Chemeré (; also La Bazouge-de-Chémeré) is a commune in the Mayenne department in northwestern France. Geography The village stands on a promontory above the Vaige river. On the opposite side there are limestone quarries and old lime kilns. The village stands at the far east of the Armorican Massif so the geology presents various facies : limestone, coal, rhyolite, slate, slate shale. There were anthracite mines dedicated to the lime kiln. The lime was used for liming (soil) until 1896 when chemical fertilizers have been available, so the lime kilns has stopped and also the mining because coal layers are not regular but spread in distant columns. History In 1926 the lightning torched the bell tower then the church. The steeple cover has been built again shorter and the bells were cast again then baptized in 1930. But the fire has brought up covered frescoes of the 16th century showing the dictation of the three dead and the three alive (three skeletons tell th ...

Mayenne
Mayenne ( ) is a landlocked department in northwest France named after the river Mayenne. Mayenne is part of the administrative region of Pays de la Loire and is surrounded by the departments of Manche, Orne, Sarthe, Maine-et-Loire, and Ille-et-Vilaine. Mayenne is one of the original 83 departments created during the French Revolution on 4 March 1790. The northern two thirds correspond to the western part of the former province of Maine. The southern third of Mayenne corresponds to the northern portion of the old province of Anjou. The inhabitants of the department are called ''Mayennais''. It had a population of 307,062 in 2019.Populations légales 2019: 53 Mayenne INSEE History Like 82 other departments, Mayenne was created on 4 March 1790 during the early stages ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Departments Of France
In the administrative divisions of France, the department (, ) is one of the three levels of government under the national level ("territorial collectivity, territorial collectivities"), between the Regions of France, administrative regions and the Communes of France, communes. There are a total of 101 departments, consisting of ninety-six departments in metropolitan France, and five Overseas department and region, overseas departments, which are also classified as overseas regions. Departments are further subdivided into 333 Arrondissements of France, arrondissements and 2,054 Cantons of France, cantons (as of 2023). These last two levels of government have no political autonomy, instead serving as the administrative basis for the local organisation of police, fire departments, and, in certain cases, elections. Each department is administered by an elected body called a departmental council (France), departmental council ( , ). From 1800 to April 2015, these were called gene ...

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 ...

Lime Kiln
A lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime called ''quicklime'' (calcium oxide). The chemical equation for this reaction is: CaCO3 + heat → CaO + CO2 This reaction can take place at anywhere above , but is generally considered to occur at (at which temperature the partial pressure of CO2 is 1 atmosphere), but a temperature around (at which temperature the partial pressure of CO2 is 3.8 atmospheres) is usually used to make the reaction proceed quickly.Parkes, G.D. and Mellor, J.W. (1939). ''Mellor's Modern Inorganic Chemistry'' London: Longmans, Green and Co. Excessive temperature is avoided because it produces unreactive, "dead-burned" lime. Slaked lime (calcium hydroxide) can be formed by mixing quicklime with water. History Pre-pottery Neolithic In plaster, proto-pottery, and mortar Because it is so readily made by heating limestone, lime must have been known from the earliest times, and all th ...

Armorican Massif
The Armorican Massif (, ) is a geologic massif that covers a large area in the northwest of France, including Brittany, the western part of Normandy and the Pays de la Loire. It is important because it is connected to Dover on the British side of the English Channel and there has been tilting back and forth that has controlled the geography on both sides. Its name comes from the old Armorica, a Gauls, Gaul area between the rivers Loire and Seine. The massif is composed of metamorphic rock, metamorphic and magmatic rocks that were metamorphism, metamorphosed and/or Deformation (geology), deformed during the Variscan orogeny, Hercynian or Variscan orogeny (400 to 280 million years ago) and the earlier Cadomian orogeny (650 to 550 million years ago). The region was tectonic uplift, uplifted when the Bay of Biscay opened during the Cretaceous period (geology), period. The Cantabrian Mountains and the Armorican Massif were then rift shoulders of the Bay of Biscay. The competence (geo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhyolite
Rhyolite ( ) is the most silica-rich of volcanic rocks. It is generally glassy or fine-grained (aphanitic) in texture (geology), texture, but may be porphyritic, containing larger mineral crystals (phenocrysts) in an otherwise fine-grained matrix (geology), groundmass. The mineral assemblage is predominantly quartz, sanidine, and plagioclase. It is the extrusive equivalent of granite. Its high silica content makes rhyolitic magma extremely viscosity, viscous. This favors explosive eruptions over effusive eruptions, so this type of magma is more often erupted as pyroclastic rock than as lava flows. Rhyolitic ash-flow tuffs are among the most voluminous of continental igneous rock formations. Rhyolitic tuff has been used extensively for construction. Obsidian, which is rhyolitic volcanic glass, has been used for tools from prehistoric times to the present day because it can be shaped to an extremely sharp edge. Rhyolitic pumice finds use as an abrasive, in concrete, and as a soil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Liming (soil)
Liming is the application of calcium- (Ca) and magnesium (Mg)-rich materials in various forms, including marl, chalk, limestone, burnt lime or hydrated lime to soil. In acid soils, these materials react as a base and neutralize soil acidity. This often improves plant growth and increases the activity of soil bacteria, but oversupply may result in harm to plant life. Modern liming was preceded by marling, a process of spreading raw chalk and lime debris across soil, in an attempt to modify pH or aggregate size. Evidence of these practices dates to the 1200's and the earliest examples are taken from the modern British Isles. Impact on soil properties Liming can also improve aggregate stability on clay soils. For this purpose structure lime, products containing calcium oxide (CaO) or hydroxide (Ca(OH)2) in mixes with calcium carbonate (CaCO3), are often used. Structure liming can reduce losses of clay and nutrients from soil aggregates. The degree to which a given amount of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ultralight Aviation
Ultralight aviation (called microlight aviation in some countries) is the flying of lightweight, 1- or 2-seat fixed-wing aircraft. Some countries differentiate between weight-shift control and Aircraft flight control system, conventional three-axis control aircraft with ailerons, Elevator (aircraft), elevator and Rudder#Aircraft rudders, rudder, calling the former "microlight" and the latter "ultralight". During the late 1970s and early 1980s, mostly stimulated by the hang gliding movement, many people sought affordable powered flight. As a result, many aviation authorities set up definitions of lightweight, slow-flying aeroplanes that could be subject to minimum regulations. The resulting aeroplanes are commonly called "ultralight aircraft" or "microlights", although the weight and speed limits differ from country to country. In Europe, the sporting (FAI) definition limits the maximum stalling speed to and the maximum take-off weight to , or if a ballistic parachute is install ...
