paragraph_text: Lepidolite is a lilac-gray or rose-colored member of the mica group of minerals with formula K(Li,Al,Rb)(Al,Si)O(F,OH). It is the most abundant lithium-bearing mineral and is a secondary source of this metal. It is a phyllosilicate mineral and a member of the polylithionite-trilithionite series.

paragraph_text: Mining was important in Thuringia since the later Middle Ages, especially within the mining towns of the Thuringian Forest such as Schmalkalden, Suhl and Ilmenau. Following the industrial revolution, the old iron, copper and silver mines declined because the competition from imported metal was too strong. On the other hand, the late 19th century brought new types of mines to Thuringia: the lignite surface mining around Meuselwitz near Altenburg in the east of the Land started in the 1870s, and two potash mining districts were established around 1900. These are the Südharzrevier in the north of the state, between Bischofferode in the west and Roßleben in the east with Sondershausen at its centre, and the Werrarevier on the Hessian border around Vacha and Bad Salzungen in the west. Together, they accounted for a significant part of the world's potash production in the mid-20th century. After the reunification, the Südharzrevier was abandoned, whereas K+S took over the mines in the Werrarevier. Between 1950 and 1990, uranium mining was also important to cover the Soviet Union's need for this metal. The centre was Ronneburg near Gera in eastern Thuringia and the operating company Wismut was under direct Soviet control.

paragraph_text: Leutenberg is a town in the district of Saalfeld-Rudolstadt, in Thuringia, Germany. It is situated in the Thuringian Forest, 18 km southeast of Saalfeld.

paragraph_text: There are over 5,300 known mineral species; as of March 2017, over 5,230 of these had been approved by the International Mineralogical Association (IMA). The silicate minerals compose over 90% of the Earth's crust. Silicon and oxygen constitute approximately 75% of the Earth's crust, which translates directly into the predominance of silicate minerals.

paragraph_text: The Spitter is a stream near Tambach-Dietharz in the Thuringian Forest in Germany. It flows through the Spitter Valley and has the highest waterfall in Thuringia. The course of the Spitter crosses the Rennsteig in the area of the Ebertswiese nature reserve and is the only stream along the route of the Rennsteig.

paragraph_text: Witherite was named after William Withering (1741–1799) an English physician and naturalist who in 1784 published his research on the new mineral. He could show that barite and the new mineral were two different minerals.

paragraph_text: The Ellenbogen is an 814-metre high extinct volcano in the Thuringian Rhön in the district of Landkreis Schmalkalden-Meiningen, Thuringia, Germany.

paragraph_text: Krokodil (, "crocodile") was a satirical magazine published in the Soviet Union. It was founded in 1922, at first as the satirical supplement to the "Workers' Gazette" (called simply «Приложения» [Supplement]); when it became a separate publication, the name 'Crocodile' was chosen at an editorial meeting from among a list of suggested animal names. At that time, a large number of satirical magazines existed, such as "Zanoza" and "Prozhektor". Nearly all of them eventually disappeared.

paragraph_text: Petrologists can also use fluid inclusion data and perform high temperature and pressure physical experiments to understand the temperatures and pressures at which different mineral phases appear, and how they change through igneous and metamorphic processes. This research can be extrapolated to the field to understand metamorphic processes and the conditions of crystallization of igneous rocks. This work can also help to explain processes that occur within the Earth, such as subduction and magma chamber evolution.

paragraph_text: Physics and Chemistry of Minerals is a peer-reviewed scientific journal published monthly by Springer Science+Business Media. The journal publishes articles and short communications on minerals or solids related to minerals and covers applications of modern techniques or new theories and models to interpret atomic structures and physical of chemical properties of minerals. Topics includes: general solid state spectroscopy, experimental and theoretical analysis of chemical bonding in minerals, physical properties, fundamental properties of atomic structure, mineral surfaces.

paragraph_text: Howard is a city in Miner County, South Dakota, United States. The population was 858 at the 2010 census. It is the county seat and most populous city in Miner County.

paragraph_text: Wallendorfer Porzellan or Wallendorf Porcelain is a porcelain manufacturing company which has been in operation since 1764 in Lichte (Wallendorf) in the Thuringian Highlands. Wallendorf is one of the oldest porcelain trademarks in Germany and the whole of Europe.

paragraph_text: Charlesite is a sulfate mineral of the ettringite group. Charlesite was named in 1945 after Dr. Charles Palache mineralogist and professor at Harvard University for his work on minerals. This mineral is extremely rare, and when it is found it is often in crystal (but not gem) form. Its crystals are soft hexagonal, that can vary in color. Colors can range from clear to white, or even a pale yellow or pink. The brittle mineral's Mohs hardness is 2.5 with a specific gravity of 1.79. Though transparent to the eye the mineral has a white streak.

paragraph_text: God Help Me is a 2006 American Christian direct-to-video romantic comedy film written and produced by Dan Olds. It was directed by Reece Tedford, and stars Tom Miner, George Moss, Jim Anderson, Candace Orrino and Shelley Findley. The film was produced by Dust Storm Productions, and distributed on July 13, 2006 by CustomFlix.

paragraph_text: Rapidcreekite was first encountered in 1983 in a tributary of Rapid Creek unofficially known as Crosscut Creek at in northern Yukon. The mineral was named "rapidcreekite" for the general area in which it was found. The mineral and name were approved by the IMA Commission on New Minerals and Mineral Names (IMA1984-035). Rapidcreekite was described in 1986 in the journal "Canadian Mineralogist".

paragraph_text: "The Crocodile" (, "Krokodil") is a short story by Fyodor Dostoyevsky that was first published in 1865 in his magazine "Epoch.

paragraph_text: Donat Mg is a natural mineral water from the springs of Rogaška Slatina in Slovenia. It has a high content of magnesium. It helps with constipation problems, heartburn and magnesium deficiency problems.

paragraph_text: Christian Frederick Matthaei (4 March 1744 in Mücheln – 26 September 1811), a Thuringian, palaeographer, classical philologist, professor first at Wittenberg and then at Moscow.

paragraph_text: Portugal is a significant European minerals producer and is ranked among Europe's leading copper producers. The nation is also a notable producer of tin, tungsten and uranium. However, the country lacks the potential to conduct hydrocarbon exploration and aluminium, a limitation that has hindered the development of Portugal's mining and metallurgy sectors. Although the country has vast iron and coal reserves—mainly in the north—after the 1974 revolution and the consequent economic globalization, low competitiveness forced a decrease in the extraction activity for these minerals. The Panasqueira and Neves-Corvo mines are among the most recognised Portuguese mines that are still in operation.[citation needed]

paragraph_text: The GDP of Thuringia is below the national average, in line with the other former East German Lands. Until 2004, Thuringia was one of the weakest regions within the European Union. The accession of several new countries, the crisis in southern Europe and the sustained economic growth in Germany since 2005 has brought the Thuringian GDP close to the EU average since then. The high economic subsidies granted by the federal government and the EU after 1990 are being reduced gradually and will end around 2020.

Question: What did the Thuringian miners do to help the country for Krokodil?
Answer: uranium mining was also important to cover the Soviet Union's need for this metal
