SudetesThe Sudetes (suːˈdiːtiːz ), commonly known as the Sudeten Mountains, is a geomorphological subprovince in Central Europe, shared by Germany, Poland and the Czech Republic. They consist mainly of mountain ranges and are the highest part of Bohemian Massif. They stretch from the Saxon capital of Dresden in the northwest across to the region of Lower Silesia in Poland and to the Moravian Gate in the Czech Republic in the east. Geographically the Sudetes are a Mittelgebirge with some characteristics typical of high mountains.
UraniniteUraninite, also known as pitchblende, is a radioactive, uranium-rich mineral and ore with a chemical composition that is largely UO2 but because of oxidation typically contains variable proportions of U3O8. Radioactive decay of the uranium causes the mineral to contain oxides of lead and trace amounts of helium. It may also contain thorium and rare-earth elements.
PirnaPirna (ˈpɪʁna; Pěrno; pjer'no) is a town in Saxony, Germany and capital of the administrative district Sächsische Schweiz-Osterzgebirge. The town's population is over 37,000. Pirna is located near Dresden and is an important district town as well as a Große Kreisstadt. Pirna is located in the vicinity of the Sandstone Mountains in the upper Elbe valley, where two nearby tributaries, Wesenitz from the north and Gottleuba from the south, flow into the Elbe. It is also called the "gate to the Saxon Switzerland" (Ger: Tor zur Sächsischen Schweiz).
Raised bogRaised bogs, also called ombrotrophic bogs, are acidic, wet habitats that are poor in mineral salts and are home to flora and fauna that can cope with such extreme conditions. Raised bogs, unlike fens, are exclusively fed by precipitation (ombrotrophy) and from mineral salts introduced from the air. They thus represent a special type of bog, hydrologically, ecologically and in terms of their development history, in which the growth of peat mosses over centuries or millennia plays a decisive role.
Bohemian MassifThe Bohemian Massif (Česká vysočina or Český masiv, Böhmische Masse or Böhmisches Massiv) is a geomorphological province in Central Europe. It is a large massif stretching over most of the Czech Republic, eastern Germany, southern Poland and northern Austria. The massif encompasses a number of mittelgebirges and consists of crystalline rocks, which are older than the Permian (more than 300 million years old) and therefore deformed during the Variscan Orogeny.
De re metallicaDe re metallica (Latin for On the Nature of Metals [Minerals]) is a book in Latin cataloguing the state of the art of mining, refining, and smelting metals, published a year posthumously in 1556 due to a delay in preparing woodcuts for the text. The author was Georg Bauer, whose pen name was the Latinized Georgius Agricola ("Bauer" and "Agricola" being respectively the German and Latin words for "farmer"). The book remained the authoritative text on mining for 180 years after its publication.
JohanngeorgenstadtJohanngeorgenstadt (ˌjoːhan.ɡeˈɔʁgŋ.ʃtat) is a mining town in Saxony’s Ore Mountains, 17 km south of Aue, and 27 km northwest of Karlovy Vary. It lies in the district of Erzgebirgskreis, on the border with the Czech Republic, is a state-recognized health resort (Erholungsort), and calls itself Stadt des Schwibbogens (“Schwibbogen Town”). Its population decline since the 1950s has been extremely severe falling from 45,000 residents in 1953 to only about one tenth of that now.
Black ForestThe Black Forest (Schwarzwald ˈʃvaʁt͡svalt) is a large forested mountain range in the state of Baden-Württemberg in southwest Germany, bounded by the Rhine Valley to the west and south and close to the borders with France and Switzerland. It is the source of the Danube and Neckar rivers. Its highest peak is the Feldberg with an elevation of above sea level. Roughly oblong in shape, with a length of and breadth of up to , it has an area of about .
MeissenMeissen (in German orthography: Meißen, ˈmaɪsn̩) is a town of approximately 30,000 about northwest of Dresden on both banks of the Elbe river in the Free State of Saxony, in eastern Germany. Meissen is the home of Meissen porcelain, the Albrechtsburg castle, the Gothic Meissen Cathedral and the Meissen Frauenkirche. The Große Kreisstadt is the capital of the Meissen district. Meissen is sometimes known as the "cradle of Saxony". It grew out of the early West Slavic settlement of Misni inhabited by Glomatians and was founded as a German town by King Henry the Fowler in 929.
