Sankt Andreasberg
Sankt Andreasberg () is a former independent city in the Goslar (district), district of Goslar, in Lower Saxony, Germany. Since 1 November 2011, it has formed part of the town Braunlage. It is situated in the Harz, approximately west of Braunlage proper, and east of Osterode am Harz. History Sankt Andreasberg was founded in the 1480s. It was first mentioned in a letter from the Count Heinrich zu Stolberg to Dietrich von Witzlebenon on 3 November 1487. The establishment of the village took place around the market. The first silver mines are assumed to be the St. Andrews Cross Mine () at the foot of the ''Beerberg'' and the St. Andrews Mine (''Grube St. Andreas'') by the market. In 1521, St. Andreasberg received the right to mine from Counts Heinrich and Ernst von Hohenstein. It was proclaimed in Mansfelder Land (district), Mansfelder Land and in the mining areas of Saxony and miners were invited to dig for silver and other metals.

Quarter (urban Subdivision)
A quarter is a part of an urban area, urban settlement. A quarter can be administratively defined and its borders officially designated, and it may have its own administrative structure (subordinate to that of the city, town or other urban area). Such a division is particularly common in countries like Bulgaria (), Croatia (), France (), Georgia (country), Georgia (, ''k'vart'ali''), Italy (), Romania (), and Serbia ( / ). It may be denoted as a borough (in English-speaking countries), Portugal/Brazil (), Spain (''barrio''); or some other term (e.g. Cambodia ( ''sangkat''), Germany (), and Poland ()). Quarter can also refer to a non-administrative but distinct neighbourhood with its own character: for example, a slum quarter. It is often used for a district connected with a particular group of people: for instance, some cities are said to have Jewish quarter (diaspora), Jewish quarters, diplomatic quarters or Bohemianism, Bohemian quarters.

Diabase
Diabase (), also called dolerite () or microgabbro, is a mafic, holocrystalline, subvolcanic rock equivalent to volcanic basalt or plutonic gabbro. Diabase dikes and sills are typically shallow intrusive bodies and often exhibit fine-grained to aphanitic chilled margins which may contain tachylite (dark mafic glass). ''Diabase'' is the preferred name in North America, while ''dolerite'' is the preferred name in the rest of the English-speaking world, where sometimes the name ''diabase'' refers to altered dolerites and basalts. Some geologists prefer to avoid confusion by using the name ''microgabbro''. The name ''diabase'' comes from the French , and ultimately from the Greek 'act of crossing over, transition', whereas the name ''dolerite'' comes from the French , from the Greek 'deceitful, deceptive', because it was easily confused with diorite. Petrography Diabase normally has a fine but visible texture of euhedral lath-shaped plagioclase crystals (62%) set i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tubing (recreation)
Tubing, also known as inner tubing, bumper tubing, towed tubing, biscuiting (in New Zealand), or kite tubing, is a recreational activity where an individual rides on top of an inner tube, either on water, snow, or through the air. The tubes themselves are also known as "donuts" or "biscuits" due to their shape. Variations Water Tubing on water generally consists of two forms: towed and free-floating, also known as river tubing. There is also water skiing. According to ''Time Magazine'', tubing was purportedly invented on the Black River (Arkansas–Missouri), Black River in Missouri by Jan & Harriet Wright of Poplar Bluff, MO sometime in the middle of the 20th century, but examples of the practice were published as early as 1916, when the popularization of the automobile meant a large supply of rubber inner tubes was available to the general public. Towed tubing usually takes place on a large body of water such as a lake or river. One or more tube riders (often called "tuber ...

Chairlift
An elevated passenger ropeway, or chairlift, is a type of aerial lift, which consists of a continuously circulating steel wire rope loop strung between two end terminals and usually over intermediate towers. They are the primary on-hill transport at most ski areas (in such cases referred to as 'ski lifts'), but are also found at amusement parks and various tourist attractions. Depending on carrier size and loading efficiency, a passenger ropeway can move up to 4,000 people per hour, and the fastest lifts achieve operating speeds of up to or . The two-person double chair, which for many years was the workhorse of the ski industry, can move roughly 1,200 people per hour at rope speeds of up to . The four person detachable chairlift ("high-speed quad") can transport 2,400 people per hour with an average rope speed of . Some bi- and tri-cable elevated ropeways and reversible tramways achieve much greater operating speeds. Design and function A chairlift consists of numerous c ...

Surface Lift
A surface lift is a type of cable transport for mountain sports in which skiers, snowboarders, or mountain bikers remain on the ground as they are pulled uphill. While they were once prevalent, they have been overtaken in popularity by higher-capacity and higher-comfort aerial lifts, such as chairlifts and gondola lifts. Today, surface lifts are most often found on beginner slopes, small ski areas, and peripheral slopes. They are also often used to access glacier ski slopes because their supports can be anchored in glacier ice due to the lower forces and realigned due to glacier movement. Surface lifts have some disadvantages compared to aerial lifts: they require more passenger skill and may be difficult for some beginners (especially snowboarders, whose boards point at an angle different than the direction of travel) and children; sometimes they lack a suitable route back to the piste; the snow surface must be continuous; they can get in the way of skiable terrain; they are ...

Sonnenberg (Harz)
The Sonnenberg is a ski resort in the Upper Harz surrounded by the Harz National Park. The settlement of the same name located there is part of the borough of Sankt Andreasberg. Topography About a kilometre southeast of the Großer Sonnenberg is the Kleiner Sonnenberg which is only 40 cm lower. The L 519 state road runs over the 830 m high saddle between the two mountains and between the village of Sonnenberg and the main town of Sankt Andreasberg. Following the line of the crest further to the southeast for a further kilometre and beyond another saddle, 833 m high, one reaches the 892 m high Rehberg. On the eastern slope of the Großer Sonnenberg is a triangulation station at a height of 838 m; this is the height shown on most topographical maps and is frequently misinterpreted as the actual height of the Großer Sonnenberg. Winter sports There are three T-bars and a rope tow on the Sonnenberg for Alpine sports. * Total piste length: 2,600 m * He ...

Brocken
The Brocken, also sometimes referred to as the Blocksberg, is a mountain near Schierke in the German state of Saxony-Anhalt, between the rivers Weser River, Weser and Elbe. The highest peak in the Harz mountain range, and in Northern Germany, it is subalpine, yet has a microclimate resembling that of mountains nearly higher. The elevation above its tree line tends to have snowcover from September to May, and mists and fogs shroud it up to 300 days a year. The mean annual temperature is only . It is the easternmost mountain in northern Germany; the next prominent elevation directly to its east would be in the Ural Mountains in Russia. The Brocken has always played a role in legends and has been connected with witches and devils; Johann Wolfgang von Goethe took up the legends in his play ''Goethe's Faust, Faust''. The Brocken spectre is a common phenomenon on this misty mountain, where a climber's shadow cast upon fog creates eerie optical effects. Today the Brocken is part of ...

Harz Granite
Harz granite (, ) is found in the Harz Mountains of central Germany. It may be divided into five types, all of which were widely used as natural stone: Knaupsholz granite, Birkenkopf granite, Wurmberg granite, Königskopf granite and Ilsestein granite. The first three granites were widely used in North Germany, Belgium and the Netherlands and, later, also in East Germany. Knaupsholz granite was ''"for a long time one of the most important types of cut stone in the former GDR"''. In 2009 only Knaupsholz granite was still being quarried. Geology The granitic plutons of the Harz Mountains - the Brocken, Ramberg and Oker plutons - were formed at the end of the Harz mountain building period (the Hercynian orogeny) during the Late Carboniferous about 300 million years ago. These natural stones were formed when large magma intrusions in the Brocken granite massif solidified at different cooling and crystallization rates into several differently coloured granites. The Harz granites ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hornfels
Hornfels is the group name for a set of Metamorphism#Contact .28thermal.29, contact metamorphic rocks that have been baked and hardened by the heat of Intrusive rock, intrusive igneous masses and have been rendered massive, hard, splintery, and in some cases exceedingly tough and durable. These properties are caused by fine grained non-aligned crystals with platy or prismatic Crystal habit, habits, characteristic of metamorphism at high temperature but without accompanying deformation. The term is derived from the German word ''Hornfels'', meaning "hornstone", because of its exceptional toughness and texture both reminiscent of animal horns. These rocks were referred to by miners in northern England as Sharpening stone, whetstones. Most hornfels are fine-grained, and while the original rocks (such as sandstone, shale, slate and limestone) may have been more or less fissile owing to the presence of bedding or Cleavage (geology), cleavage planes, this structure is effaced or rendered ...

Greywacke
Greywacke or graywacke ( ) is a variety of sandstone generally characterized by its hardness (6–7 on Mohs scale), dark color, and Sorting (sediment), poorly sorted angular grains of quartz, feldspar, and small rock fragments or sand-size Lithic fragment (geology), lithic fragments set in a compact, clay-fine matrix. It is a texturally immature sedimentary rock generally found in Paleozoic Stratum, strata. The larger Particle size (grain size), grains can be sand- to gravel-sized, and Matrix (geology), matrix materials generally constitute more than 15% of the rock by volume. Formation The origin of greywacke was unknown until turbidity currents and turbidites were understood, since, according to the normal laws of sedimentation, gravel, sand and mud should not be laid down together. Geologists now attribute its formation to submarine avalanches or strong turbidity currents. These actions churn sediment and cause mixed-sediment slurries, in which the resulting deposits may ex ...
