Spannagel Cave
The Spannagel Cave (german: Spannagelhöhle) is a show cave near Hintertux, in the Zillertal Alps in the Austrian state of Tyrol. Currently about 10 kilometres of cave have been discovered; guided tours enable access to 500 metres of the cave. Its entrance lies below the Spannagelhaus (2531 m), a mountain hut formerly run by the Austrian Tourist Club (ÖTK). The cave and the hut are named after Dr. Rudolf Spannagel, who was the president of the ÖTK from 1902 to 1904. Formation The overwhelming part of the Zillertal Alps consists of the crystalline primary rocks, plutons and metamorphic rock, that do not support the formation of caves. The only exceptions are pockets of rock capable of karstification such as limestone, dolomite, gypsum and other carbonates. These pockets are generally of quite low thickness, and only allow small caves to be formed. The creation of caves also requires water solubility. The Spannagel Cave has arisen in a large vein of Jurassic calcite marble of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tux (Tirol)
Tux is a municipality in the Schwaz district in the Austrian state of Tyrol. Geography The parish of Tux covers the higher and largest part of the Tuxertal, a side valley of the Zillertal that branches off at Mayrhofen. The territory of the parish extends to the glaciated peak of Olperer (3,476 m) and the 2,338 m high saddle of the Tuxer Joch, a crossing between the Zillertal and Wipptal valleys that was heavily used even in the protohistoric period. Other prominent peaks within the municipality are the 3,288 m high Gefrorene Wand Spitze and the 3,231 m high Hoher Riffler. The highest farmsteads lie at a height of 1,630 m. Tux consists of the five villages of Tux-Vorderlanersbach (former Vorderlanersbach), Tux-Lanersbach (former Lanersbach), Juns, Madseit, and Hintertux. On 25 January 2005 the state government renamed Lanersbach to Tux-Lanersbach and Vorderlanersbach to Tux-Vorderlanersbach because, although the municipality as a whole was called Tux, th ...

Corrosion
Corrosion is a natural process that converts a refined metal into a more chemically stable oxide. It is the gradual deterioration of materials (usually a metal) by chemical or electrochemical reaction with their environment. Corrosion engineering is the field dedicated to controlling and preventing corrosion. In the most common use of the word, this means electrochemical oxidation of metal in reaction with an oxidant such as oxygen, hydrogen or hydroxide. Rusting, the formation of iron oxides, is a well-known example of electrochemical corrosion. This type of damage typically produces oxide(s) or salt(s) of the original metal and results in a distinctive orange colouration. Corrosion can also occur in materials other than metals, such as ceramics or polymers, although in this context, the term "degradation" is more common. Corrosion degrades the useful properties of materials and structures including strength, appearance and permeability to liquids and gases. Many structural ...

Protected Areas Of Austria
Protection is any measure taken to guard a thing against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage serving ...

Natural Monument
A natural monument is a natural or natural/cultural feature of outstanding or unique value because of its inherent rarity, representative of aesthetic qualities or cultural significance. Under World Commission on Protected Areas guidelines, natural monuments are level III, described as: :"Areas are set aside to protect a specific natural monument, which can be a landform, sea mount, submarine cavern, geological feature such as a cave or even a living feature such as an ancient grove. They are generally quite small protected areas and often have high visitor value." This is a lower level of protection than level II (national parks) and level I (wilderness areas). The European Environment Agency's guidelines for selection of a natural monument are: * The area should contain one or more features of outstanding significance. Appropriate natural features include waterfalls, caves, craters, fossil beds, sand dunes and marine features, along with unique or representative fauna and flo ...

Kolk (vortex)
A kolk (colc) is an underwater vortex created when rapidly rushing water passes an underwater obstacle in boundary areas of high shear. High-velocity gradients produce a violently rotating column of water, similar to a tornado. Kolks can pluck multiple-ton blocks of rock and transport them in suspension for thousands of metres. Kolks leave clear evidence in the form of plucked-bedrock pits, called rock-cut basins or kolk lakes and downstream deposits of gravel-supported blocks that show percussion but no rounding. Examples Kolks were first identified by the Dutch, who observed kolks hoisting several-ton blocks of riprap from dikes and transporting them away, suspended above the bottom. The Larrelt kolk near Emden appeared during the 1717 Christmas flood which broke through a long section of the dyke. The newly formed body of water measured roughly 500 × 100 m and was 25 m deep. In spite of the repair to the dyke, another breach occurred in 1721, which produced mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Speleothem
A speleothem (; ) is a geological formation by mineral deposits that accumulate over time in natural caves. Speleothems most commonly form in calcareous caves due to carbonate dissolution reactions. They can take a variety of forms, depending on their depositional history and environment. Their chemical composition, gradual growth, and preservation in caves make them useful paleoclimatic proxies. Chemical and physical characteristics More than 300 variations of cave mineral deposits have been identified. The vast majority of speleothems are calcareous, composed of calcium carbonate (CaCO3) minerals (calcite or aragonite). Less commonly, speleothems are made of calcium sulfate (gypsum or mirabilite) or opal. Speleothems of pure calcium carbonate or calcium sulfate are translucent and colorless. The presence of iron oxide or copper provides a reddish brown color. The presence of manganese oxide can create darker colors such as black or dark brown. Speleothems can also be brown d ...

Calc-sinter
Calcareous sinter is a freshwater calcium carbonate deposit, also known as calc-sinter. Deposits are characterised by low porosity and well-developed lamination, often forming crusts or sedimentary rock layers. Calcareous sinter should not be confused with siliceous sinter, which the term sinter more frequently refers to. It has been suggested that the term "sinter" should be restricted to siliceous spring deposits and be dropped for calcareous deposits entirely. Features Calcareous sinter is characterised by laminations of prismatic crystals growing perpendicular to the substrate; laminations are separated by thin layers of microcrystalline carbonate. Calcareous sinter is porous due to the calcareous crystals enclosing many small cavities. Macrophytes are absent, consequently porosity is very low. Exclusion of species is due either to high temperature (travertine), high pH/ionic strength (tufa) or absence of light (speleothems). Pedley (1990) suggests the term be abandoned in ...

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.
