La Bazouge-de-Chemeré
La Bazouge-de-Chemeré () is a Communes of France, commune in the Mayenne Departments of France, 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. Luckily 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 spraid 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 ...

Communes Of France
The () is a level of administrative division in the French Republic. French are analogous to civil townships and incorporated municipalities in the United States and Canada, ' in Germany, ' in Italy, or ' in Spain. The United Kingdom's equivalent are civil parishes, although some areas, particularly urban areas, are unparished. are based on historical geographic communities or villages and are vested with significant powers to manage the populations and land of the geographic area covered. The are the fourth-level administrative divisions of France. vary widely in size and area, from large sprawling cities with millions of inhabitants like Paris, to small hamlets with only a handful of inhabitants. typically are based on pre-existing villages and facilitate local governance. All have names, but not all named geographic areas or groups of people residing together are ( or ), the difference residing in the lack of administrative powers. Except for the municipal arrondi ...

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''.

Departments Of France
In the administrative divisions of France, the department (french: département, ) is one of the three levels of government under the national level ("territorial collectivities"), between the administrative regions and the communes. Ninety-six departments are in metropolitan France, and five are overseas departments, which are also classified as overseas regions. Departments are further subdivided into 332 arrondissements, and these are divided into cantons. The last two levels of government have no autonomy; they are the basis of local organisation of police, fire departments and, sometimes, administration of elections. Each department is administered by an elected body called a departmental council ( ing. lur.. From 1800 to April 2015, these were called general councils ( ing. lur.. Each council has a president. Their main areas of responsibility include the management of a number of social and welfare allowances, of junior high school () buildings and technical staff, ...

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] |
Lime Kiln
A lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime (material), lime called quicklime (calcium oxide). The chemical equation for this chemical reaction, reaction is :Calcium carbonate, CaCO3 + heat → Calcium oxide, CaO + Carbon dioxide, CO2 This reaction can take place at anywhere above 840 °C (1544 °F), but is generally considered to occur at 900 °C(1655 °F) (at which temperature the partial pressure of CO2 is 1 atmosphere (unit), atmosphere), but a temperature around 1000 °C (1832 °F) (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. Early li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armorican Massif
The Armorican Massif (french: Massif armoricain, ) 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 Gaul area between the rivers Loire and Seine. The massif is composed of metamorphic and magmatic rocks that were metamorphosed and/or deformed during the Hercynian or Variscan orogeny (400 to 280 million years ago) and the earlier Cadomian orogeny (650 to 550 million years ago). The region was uplifted when the Bay of Biscay opened during the Cretaceous period. The Cantabrian Mountains and the Armorican Massif were then rift shoulders of the Bay of Biscay. The competent old rocks of the Armorican Massif have been eroded to a plateaulike peneplain. The highes ... [...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, but may be porphyritic, containing larger mineral crystals (phenocrysts) in an otherwise fine-grained groundmass. The mineral assemblage is predominantly quartz, sanidine, and plagioclase. It is the extrusive equivalent to granite. Rhyolitic magma is extremely viscous, due to its high silica content. 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 extensively used 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 amendment. Description Rhyolite i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anthracite
Anthracite, also known as hard coal, and black coal, is a hard, compact variety of coal that has a submetallic luster. It has the highest carbon content, the fewest impurities, and the highest energy density of all types of coal and is the highest ranking of coals. Anthracite is the most metamorphosed type of coal (but still represents low-grade metamorphism), in which the carbon content is between 86% and 97%. The term is applied to those varieties of coal which do not give off tarry or other hydrocarbon vapours when heated below their point of ignition. Anthracite ignites with difficulty and burns with a short, blue, and smokeless flame. Anthracite is categorized into standard grade, which is used mainly in power generation, high grade (HG) and ultra high grade (UHG), the principal uses of which are in the metallurgy sector. Anthracite accounts for about 1% of global coal reserves, and is mined in only a few countries around the world. The Coal Region of northeastern Pen ...

Liming (soil)
Liming is the application (to soil) of calcium- (Ca) and magnesium (Mg)-rich materials in various forms, including marl, chalk, limestone, burnt lime or hydrated lime. 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. 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 lime per unit of soil volume will increase soil pH depends on the buffer capacity of the soil (this is generally related to soil cation exchange capacity or CEC). Soils with low CEC will usually show a more marked pH increase than soils with high CEC. But the low-CEC soils will witness more r ...

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 conventional three-axis control aircraft with ailerons, elevator and 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 installed. The definition means that the aircraft has a slow landing speed and short ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
