Großer Auerberg
The Große Auerberg is a hill, high, in the eastern Harz in the district of Mansfeld-Südharz in the German state of Saxony-Anhalt. It is a so-called double peak with summits that are 580.4 metres high (''Großer Auerberg'') and 580.3 metres high (''Josephshöhe''), which are about 470 metres apart. Location The Große Auerberg rises within the Harz/Saxony-Anhalt Nature Park between Straßberg to the northeast, Hayn to the southeast, Schwenda to the south, Stolberg to the southwest and Breitenstein to the northwest. East of the hill is the source of the Thyra tributary, the ''Krummschlachtbach'', west of the Thyra headstream, the ''Kleine Wilde''. Geology The Auerberg is made of rhyolite ( quartz porphyry), a volcanic rock. In the fine crystalline matrix (''Grundmasse'') are deposits of "Stolberg Diamonds" (''Stolberger Diamanten''), up to 13 mm thick, crystallised-out quartz and orthoclase grains.

Harz Mountains
The Harz () is a highland area in northern Germany. It has the highest elevations for that region, and its rugged terrain extends across parts of Lower Saxony, Saxony-Anhalt, and Thuringia. The name ''Harz'' derives from the Middle High German word ''Hardt'' or ''Hart'' (hill forest). The name ''Hercynia'' derives from a Celtic name and could refer to other mountain forests, but has also been applied to the geology of the Harz. The Brocken is the highest summit in the Harz with an elevation of above sea level. The Wurmberg () is the highest peak located entirely within the state of Lower Saxony. Geography Location and extent The Harz has a length of , stretching from the town of Seesen in the northwest to Eisleben in the east, and a width of . It occupies an area of , and is divided into the Upper Harz (''Oberharz'') in the northwest, which is up to 800 m high, apart from the 1,100 m high Brocken massif, and the Lower Harz (''Unterharz'') in the east which is up to aroun ...

Thyra (river)
The Thyra is a river of Saxony-Anhalt, Germany, in the district of Mansfeld-Südharz in the Harz Mountains. Course The Thyra begins its course in the old quarter of Stolberg in the Harz Mountains at the confluence of three mountain streams - the Große Wilde, Kleine Wilde and Lude - and then flows through Stolberg, where several streams join it, before heading south through a steep valley to Rottleberode. Here the Thyra valley becomes very wide, but near Uftrungen it narrows again. South of Uftrungen the Thyra leaves the Harz and enters the Goldene Aue, crossing and Berga, before this little river enters the Helme. Influence Several things are named after the Thyra, for example the Thyra thermal baths (''Thyratherme'') in Stolberg or the railway line known as the Thyraliesel.

Mountains And Hills Of Saxony-Anhalt
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

Landesstraße
''Landesstraßen'' (singular: ''Landesstraße'') are roads in Germany and Austria that are, as a rule, the responsibility of the respective German or Austrian federal state. The term may therefore be translated as "state road". They are roads that cross the boundary of a rural or urban district (''Landkreis'' or ''Kreisfreie Stadt''). A ''Landesstraße'' is thus less important than a ''Bundesstraße'' or federal road, but more significant than a ''Kreisstraße'' or district road. The classification of a road as a ''Landesstraße'' is a legal matter (''Widmung''). In the free states of Bavaria and Saxony – but not, however, in the Free State of Thuringia – ''Landesstraßen'' are known as ''Staatsstraßen''. Designation The abbreviation for a ''Landesstraße'' consists of a prefixed capital letter ''L'' and a serial number (e. g. L 1, L 83, L 262 or L 3190). ''Staatsstraßen'' in Saxony are similarly abbreviated using a capital ''S'' (e. g. S 190) and the ''Staatsstraßen' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harzer Wandernadel
The Harzer Wandernadel is a system of hiking awards in the Harz mountains in central Germany. The hiker (or mountain biker) can earn awards at different levels of challenge by walking to the various checkpoints in the network and stamping his or her passbook to record the visit. With 222 checkpoints in three federal states and across five districts in the Harz and with membership in five figures, the system has gained a following Germany-wide. Purpose The idea of the ''Wandernadel'' (literally "hiking needle/pin" --> "hiking badge") is to give those holidaying in the Harz a worthwhile goal to achieve and encourage them to stay for longer or return. It also aims to encourage those who live in the local area to go hiking and improve their fitness. In addition the system helps tourists and locals to get to know the many different sights and hiking trails in the Harz. To that end, checkpoints have been located at scenic viewing points, places of geological or botanical, culturalbo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orthoclase
Orthoclase, or orthoclase feldspar (endmember formula K Al Si3 O8), is an important tectosilicate mineral which forms igneous rock. The name is from the Ancient Greek for "straight fracture," because its two cleavage planes are at right angles to each other. It is a type of potassium feldspar, also known as K-feldspar. The gem known as moonstone (see below) is largely composed of orthoclase. Formation and subtypes Orthoclase is a common constituent of most granites and other felsic igneous rocks and often forms huge crystals and masses in pegmatite. Typically, the pure potassium endmember of orthoclase forms a solid solution with albite, the sodium endmember (NaAlSi3O8), of plagioclase. While slowly cooling within the earth, sodium-rich albite lamellae form by exsolution, enriching the remaining orthoclase with potassium. The resulting intergrowth of the two feldspars is called perthite. The higher-temperature polymorph of KAlSi3O8 is sanidine. Sanidine is common in rapidly ...

Quartz
Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). The atoms are linked in a continuous framework of SiO4 silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar. Quartz exists in two forms, the normal α-quartz and the high-temperature β-quartz, both of which are chiral. The transformation from α-quartz to β-quartz takes place abruptly at . Since the transformation is accompanied by a significant change in volume, it can easily induce microfracturing of ceramics or rocks passing through this temperature threshold. There are many different varieties of quartz, several of which are classified as gemstones. Since antiquity, varieties of quartz have been the most commonly used minerals in the making of jewelry and hardstone carvings, especially in Eurasia. Quartz is the mineral defining the val ...

Vulcanite
Vulcanite is a rare copper telluride mineral. The mineral has a metallic luster, and has a green or bronze-yellow tint. It has a hardness between 1 and 2 on the Mohs scale (between talc and gypsum). Its crystal structure is orthorhombic. Vulcanite is named for the place where it was discovered in 1961, the Mammoth Good Hope Mine in Vulcan (ghost town and district), Gunnison County, Colorado. Small deposits have also been discovered in Japan, Russia, Saudi Arabia, and Norway. It occurs with native tellurium, rickardite, petzite, and sylvanite. See also *Telluride mineral A telluride mineral is a mineral that has the telluride anion as a main component.

Quartz Porphyry
Quartz-porphyry, in layman's terms, is a type of volcanic (igneous) rock containing large porphyritic crystals of quartz. These rocks are classified as ''hemi-crystalline acid rocks''. Structure The quartz crystals exist in a fine-grained matrix, usually of micro-crystalline or felsitic structure. In specimens, the quartz appears as small rounded, clear, greyish, vitreous blebs, which are crystals, double hexagonal pyramids, with their edges and corners rounded by resorption or corrosion. Under the microscope they are often seen to contain rounded enclosures of the ground-mass or fluid cavities, which are frequently negative crystals with regular outlines resembling those of perfect quartz crystals. Many of the latter contain liquid carbonic acid and a bubble of gas that may exhibit vibratile motion under high magnifying powers. Variants In addition to quartz there are usually phenocrysts of feldspar, mostly orthoclase, though a varying amount of plagioclase is often presen ...

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] |
