Hüttenstollen
The Hüttenstollen, also Straßberger Hüttenstollen, was the central drainage adit in the Straßberg (Harz), Straßberg mining field and was also part of the Lower Harz Pond and Ditch System in the Harz Mountains of Germany. The adit lies at a depth of 50 m and is 750 m long. The pit water was drained into the Selke (river), Selke. The drainage ditches were the Straßberger ''Flösse'' and the ''Stollgraben''. History The construction of a deep adit had begun before 1696. The aim was to provide ventilation for the pits at Straßberg: the ''Segen Gottes'', ''Hilfe Gottes'', ''Gott hilft gewiß'' and ''Grube Vertrau auf Gott, Vertrau auf Gott'' (later, the Glasebach Pit). Georg Christoph von Utterodt, who came from Ilmenau, took over the running of the Straßberg mines in 1701. In the years that followed the adit was driven out from the Selke (river), Selke valley. Under Christian Zacharias Koch the adit, which had since been named the Hüttenstollen was further extended in 1720. ...

Lower Harz Pond And Ditch System
Within the Lower Harz region (in the counties of Harz and Mansfeld-Südharz in central Germany) are still many traces of the historical water management facilities used by the mining industry. In addition to water-carrying ditches and ponds, there are also long-abandoned ditches and dry pond beds. The Lower Harz Pond and Ditch System (), which forms the major part of these old water management facilities, lies in the central Lower Harz, almost entirely within the borough of the present-day town of Harzgerode. Extent In the central Lower Harz between the villages of Neudorf, Silberhütte, Straßberg, Großem Auerberg and the upper Lude river is the only, historical, mine water management system in the Lower Harz. Sheltered by the geographical-climatic conditions of the Lower Harz, the system never reached the scale of comparable systems in the Upper Harz and the Ore Mountains. The river catchment areas affected are primarily the source regions and upper reaches of small mount ...

Selke (river)
The Selke is a river of Saxony-Anhalt, Germany. It is a right-hand tributary of the Bode (river), Bode that starts in the Harz Mountains before breaking out onto the northeastern Harz Foreland. It has a length of , of which lie in the forested mountains of the Harz and the rest on the agricultural lowlands of the Harz Foreland. Course The Selke rises near the village of Friedrichshöhe in the borough of Güntersberge at a height of about above Normalnull, NN. From Friedrichshöhe to Mägdesprung in the borough of Harzgerode, it is accompanied by the Selke Valley Railway for a distance of . The Selke has cut deeply into the Harz Mountains in some places whilst in others it runs in a broad valley, depending on the bedrock. In Meisdorf on the northeastern edge of the Lower Harz, the Selke leaves the forested mountain region and winds across a cultivated plain, continuing to flow in an easterly or northeasterly direction as far as Ermsleben. Beyond Ermsleben the river swings t ...

Adit
An adit (from Latin ''aditus'', entrance) or stulm is a horizontal or nearly horizontal passage to an underground mine. Miners can use adits for access, drainage, ventilation, and extracting minerals at the lowest convenient level. Adits are also used to explore for mineral veins. Although most strongly associated with mining, the term ''adit'' is sometimes also used in the context of underground excavation for non-mining purposes; for example, to refer to smaller underground passageways excavated for underground metro systems, to provide pedestrian access to stations (pedestrian adits), and for access required during construction (construction adits). Construction Adits are driven into the side of a hill or mountain, and are often used when an ore body is located inside the mountain but above the adjacent valley floor or coastal plain. In cases where the mineral vein outcrops at the surface, the adit may follow the lode or vein until it is worked out, in which case the ad ...

Calcite
Calcite is a Carbonate minerals, carbonate mineral and the most stable Polymorphism (materials science), polymorph of calcium carbonate (CaCO3). It is a very common mineral, particularly as a component of limestone. Calcite defines hardness 3 on the Mohs scale of mineral hardness, based on Scratch hardness, scratch hardness comparison. Large calcite crystals are used in optical equipment, and limestone composed mostly of calcite has numerous uses. Other polymorphs of calcium carbonate are the minerals aragonite and vaterite. Aragonite will change to calcite over timescales of days or less at temperatures exceeding 300 °C, and vaterite is even less stable. Etymology Calcite is derived from the German , a term from the 19th century that came from the Latin word for Lime (material), lime, (genitive ) with the suffix ''-ite'' used to name minerals. It is thus a Doublet (linguistics), doublet of the word ''wikt:chalk, chalk''. When applied by archaeology, archaeologists and ...

Mining In The Harz
Mining in the Upper Harz region of central Germany was a major industry for several centuries, especially for the production of silver, lead, copper, and, latterly, zinc as well. Great wealth was accumulated from the mining of silver from the 16th to the 19th centuries, as well as from important technical inventions. The centre of the mining industry was the group of seven Upper Harz mining towns of Clausthal-Zellerfeld, Clausthal, Zellerfeld, Sankt Andreasberg, Wildemann, Bad Grund, Grund, Lautenthal und Altenau, Lower Saxony, Altenau. History The Upper Harz was once one of the most important mining regions in Germany. The major products of its mines were silver, copper, lead, iron and, from the 19th century, zinc as well. The main source of income, however, was silver. From the 16th to the middle of the 19th centuries about 40–50% of the entire German silver production originated in the Upper Harz. The taxes raised from this contributed significantly to the revenue of the ro ...

Dennert Fir Tree
The Dennert Fir Tree (, also known as the , or ) is a signboard that is used throughout the Harz mountains in Germany to provide information about mining and other points of interest in the area. The signboards mark locations, traces and monuments to mining, to the Upper Harz Water Regale, a medieval water management system, or even personalities in mining history in the Upper Harz mining area. They have since become used to document other notable sites within the Harz. The first Dennert Fir Tree was set up on 9 October 1949 in the vicinity of the former Sarepta Pit () in Clausthal. It was sponsored by the Power and Water Management Division () of Preussag AG, the operator of the Upper Harz Water Regalem at that time. The instigator was Herbert Dennert (1902–1994). Dennert promoted the preservation of mining monuments and published several books about mining in the Upper Harz. The signs measure and are mainly made of wood and have the characteristic shape of a stylised ...

Galena
Galena, also called lead glance, is the natural mineral form of lead(II) sulfide (PbS). It is the most important ore of lead and an important source of silver. Galena is one of the most abundant and widely distributed sulfide minerals. It crystallizes in the Cubic (crystal system), cubic crystal system often showing octahedral forms. It is often associated with the minerals sphalerite, calcite and fluorite. As a pure specimen held in the hand, under standard temperature and pressure, galena is insoluble in water and so is almost non-toxic. Handling galena under these specific conditions (such as in a museum or as part of geology instruction) poses practically no risk; however, as lead(II) sulfide is reasonably reactive in a variety of environments, it can be highly toxic if swallowed or inhaled, particularly under prolonged or repeated exposure. Occurrence Galena is the main ore of lead, used since ancient times, since lead can be smelted from galena in an ordinary wood fire. G ...

Quartz
Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). The Atom, atoms are linked in a continuous framework of SiO4 silicon–oxygen Tetrahedral molecular geometry, tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of Silicon dioxide, SiO2. Quartz is, therefore, classified structurally as a Silicate mineral#Tectosilicates, framework silicate mineral and compositionally as an oxide mineral. 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 classifi ...
