German Continental Deep Drilling Programme
The German Continental Deep Drilling Programme (german: Kontinentales Tiefbohrprogramm der Bundesrepublik Deutschland, lit=Continental deep-drilling program of the Federal Republic of Germany, abbreviated as the KTB borehole, was a scientific drilling project carried out from 1987 to 1995 near Windischeschenbach, Bavaria. The main super-deep borehole reached a depth of in the Earth's continental crust. The Federal Ministry of Research funded the project with 528 million DM (270 million euros). The (Lower Saxony) LBEG mining office (State Office for Mining, Energy and Geology) took the project lead. After the drilling project ended, the German Research Centre for Geosciences used the borehole to install a seismic deep observatory () which was active from 1996 to 2001. The derrick used at the site, one of the largest in the world, remains in place and has become a tourist attraction. The two boreholes were kept open for further scientific research and for in-situ testing of equ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bavaria
Bavaria ( ; ), officially the Free State of Bavaria (german: Freistaat Bayern, link=no ), is a state in the south-east of Germany. With an area of , Bavaria is the largest German state by land area, comprising roughly a fifth of the total land area of Germany. With over 13 million inhabitants, it is second in population only to North Rhine-Westphalia, but due to its large size its population density is below the German average. Bavaria's main cities are Munich (its capital and largest city and also the third largest city in Germany), Nuremberg, and Augsburg. The history of Bavaria includes its earliest settlement by Iron Age Celtic tribes, followed by the conquests of the Roman Empire in the 1st century BC, when the territory was incorporated into the provinces of Raetia and Noricum. It became the Duchy of Bavaria (a stem duchy) in the 6th century AD following the collapse of the Western Roman Empire. It was later incorporated into the Holy Roman Empire, be ...

Scientific Drilling
Scientific drilling into the Earth is a way for scientists to probe the Earth's sediments, crust, and upper mantle. In addition to rock samples, drilling technology can unearth samples of connate fluids and of the subsurface biosphere, mostly microbial life, preserved in drilled samples. Scientific drilling is carried out on land by the International Continental Scientific Drilling Program (ICDP) and at sea by the Integrated Ocean Drilling Program (IODP). Scientific drilling on the continents includes drilling down into solid ground as well as drilling from small boats on lakes. Sampling thick glaciers and ice sheets to obtain ice cores is related but will not be described further here. Like probes sent into outer space, scientific drilling is a technology used to obtain samples from places that people cannot reach. Human beings have descended as deep as 2,212 m (7,257 ft) in Veryovkina Cave, the world's deepest known cave, located in the Caucasus mountains of the country of ...

Continental Crust
Continental crust is the layer of igneous, sedimentary, and metamorphic rocks that forms the geological continents and the areas of shallow seabed close to their shores, known as continental shelves. This layer is sometimes called '' sial'' because its bulk composition is richer in aluminium silicates (Al-Si) and has a lower density compared to the oceanic crust, called ''sima'' which is richer in magnesium silicate (Mg-Si) minerals. Changes in seismic wave velocities have shown that at a certain depth (the Conrad discontinuity), there is a reasonably sharp contrast between the more felsic upper continental crust and the lower continental crust, which is more mafic in character. The continental crust consists of various layers, with a bulk composition that is intermediate (SiO2 wt% = 60.6). The average density of continental crust is about , less dense than the ultramafic material that makes up the mantle, which has a density of around . Continental crust is also less dense ...

Federal Ministry Of Education And Research (Germany)
The Federal Ministry of Education and Research (german: link=no, Bundesministerium für Bildung und Forschung, ), abbreviated BMBF, is a cabinet-level ministry of Germany. It is headquartered in Bonn, with an office in Berlin. The Ministry provides funding for research projects and institutions (aiming for "research excellence") and sets general educational policy. It also provides student loans in Germany. However, a large part of educational policy in Germany is decided at the state level, strongly limiting the influence of the ministry in educational matters. History The ''Federal Ministry for Atomic Issues'' was established in 1955, concentrating on research in the peaceful use of nuclear energy. The ministry was renamed in 1962 to ''Federal Ministry of Scientific Research'', with a broader scope; it was renamed again, to ''Federal Ministry of Education and Science'', in 1969. A separate ministry, the ''Federal Ministry of Research and Technology'', was established in 1972. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deutsche Mark
The Deutsche Mark (; English: ''German mark''), abbreviated "DM" or "D-Mark" (), was the official currency of West Germany from 1948 until 1990 and later the unified Germany from 1990 until the adoption of the euro in 2002. In English, it was typically called the "Deutschmark" (). One Deutsche Mark was divided into 100 pfennigs. It was first issued under Allied occupation in 1948 to replace the Reichsmark and served as the Federal Republic of Germany's official currency from its founding the following year. On 31 December 1998, the Council of the European Union fixed the irrevocable exchange rate, effective 1 January 1999, for German mark to euros as DM 1.95583 = €1. In 1999, the Deutsche Mark was replaced by the euro; its coins and banknotes remained in circulation, defined in terms of euros, until the introduction of euro notes and coins on 1 January 2002. The Deutsche Mark ceased to be legal tender immediately upon the introduction of the euro—in contrast to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GFZ German Research Centre For Geosciences

Derrick
A derrick is a lifting device composed at minimum of one guyed mast, as in a gin pole, which may be articulated over a load by adjusting its guys. Most derricks have at least two components, either a guyed mast or self-supporting tower, and a boom hinged at its base to provide articulation, as in a ''stiffleg'' derrick. The most basic type of derrick is controlled by three or four lines connected to the top of the mast, which allow it both to move laterally and cant up and down. To lift a load, a separate line runs up and over the mast with a hook on its free end, as with a crane. Forms of derricks are commonly found aboard ships and at docking facilities. Some large derricks are mounted on dedicated vessels, and known as floating derricks and sheerlegs. The term derrick is also applied to the framework supporting a drilling apparatus in an oil rig. The derrick derives its name from a type of gallows named after Thomas Derrick, an Elizabethan era English executioner. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kola Superdeep Borehole
The Kola Superdeep Borehole (russian: Кольская сверхглубокая скважина, translit=Kol'skaya sverkhglubokaya skvazhina) SG-3 is the result of a scientific drilling project of the Soviet Union in the Pechengsky District, near the Russian border with Norway, on the Kola Peninsula. The project attempted to drill as deep as possible into the Earth's crust. Drilling began on 24 May 1970 using the '' Uralmash-4E'', and later the ''Uralmash-15000'' series drilling rig, and it became the deepest manmade hole in history in 1979. The diameter boreholes were drilled by branching from a central hole. The deepest reached in 1989, the deepest human-made hole on Earth, and remains so as of 2022. In terms of true vertical depth, it remains the deepest borehole in the world. For two decades, it was also the world's longest borehole in terms of measured depth along the well bore until it was surpassed in 2008 by the long Al Shaheen Oil Well in Qatar. Dri ...

Geothermal Gradient
Geothermal gradient is the rate of temperature change with respect to increasing depth in Earth's interior. As a general rule, the crust temperature rises with depth due to the heat flow from the much hotter mantle; away from tectonic plate boundaries, temperature rises in about 25–30 °C/km (72–87 °F/mi) of depth near the surface in most of the world. However, in some cases the temperature may drop with increasing depth, especially near the surface, a phenomenon known as ''inverse'' or ''negative'' geothermal gradient. The effects of weather, sun, and season only reach a depth of approximately 10-20 metres. Strictly speaking, ''geo''-thermal necessarily refers to Earth but the concept may be applied to other planets. In SI units, the geothermal gradient is expressed as °C/km, K/km, or mK/m. These are all equivalent. Earth's internal heat comes from a combination of residual heat from planetary accretion, heat produced through radioactive decay, latent heat f ...
