Štiavnica Mountains
The Štiavnica Mountains (also Štiavnické Mountains; sk, Štiavnické vrchy, ) are a volcanic mountain range southern central Slovakia. They are part of Inner Western Carpathians and the Slovenské stredohorie Mountains. The area is protected by Štiavnica Mountains Protected Landscape Area. They are bordered by the Kremnica Mountains (''Kremnické vrchy'') in the north, Pliešovce and Krupina basins (''Krupinská kotlina'') in the east, Danubian Hills (''Podunajská pahorkatina'') in the south and Pohronský Inovec, Vtáčnik and Žiar Basin (''Žiarska kotlina'') in the west. The highest point is Sitno (1,009 m). Štiavnica Mountains are an immense caldera created by the collapse of an ancient volcano. Due to their volcanic origin, they are mineral-rich, with around 140 kinds of minerals. In the past, silver mining flourished in the area around the town of Banská Štiavnica. From originally over 60 lakes called tajchy Tajchy (singular: tajch, from German ''Teich'') ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tajchy
Tajchy (singular: tajch, from German ''Teich'') are artificial water reservoirs in the Štiavnica Mountains, in central Slovakia. Most of them were built in order to provide energy for the silver mines of Banská Štiavnica in the 18th century. At their height, tajchy comprised a sophisticated system of 60 reservoirs, connected to each other by more than 100 km of channels and tunnels. 24 artificial lakes still exist and serve recreational purposes. Because of their historical value, tajchy were proclaimed by the UNESCO to be a World Heritage Site on 11 December 1993, together with the town of Banská Štiavnica and technical historical monuments in its surroundings. Operation The region of Banská Štiavnica lacks significant sources of flowing surface water. That is why tajchy were designed to store water derived from precipitation. Channels with the overall length of 72 km diverted water from the rain and melting snow to sixty reservoirs. The whole system could a ...

Banská Štiavnica
Banská Štiavnica (; german: Schemnitz; hu, Selmecbánya (Selmec), ) is a town in central Slovakia, in the middle of an immense caldera created by the collapse of an ancient volcano. For its size, the caldera is known as the Štiavnica Mountains. Banská Štiavnica has a population of more than 10,000. It is a completely preserved medieval town. Because of their historical value, the town and its surroundings were proclaimed by the UNESCO to be a World Heritage Site on December 11, 1993. History The fate of Banská Štiavnica has been closely linked to the exploitation of its abundant resources of silver ore. According to evidence from excavations, the site was settled during the Neolithic period. The first mining settlement was founded by Celts in the 3rd century BC. It was probably occupied by the Celtic Cotini tribe. Roman authors mentioned mining activities of the Cotini, who had lived in present-day central Slovakia until they were deported to Pannonia within the Marcomann ...

Silver
Silver is a chemical element with the Symbol (chemistry), symbol Ag (from the Latin ', derived from the Proto-Indo-European wikt:Reconstruction:Proto-Indo-European/h₂erǵ-, ''h₂erǵ'': "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc Refining (metallurgy), refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes bimetallism, alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mineral
In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid chemical compound with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form.John P. Rafferty, ed. (2011): Minerals'; p. 1. In the series ''Geology: Landforms, Minerals, and Rocks''. Rosen Publishing Group. The geological definition of mineral normally excludes compounds that occur only in living organisms. However, some minerals are often biogenic (such as calcite) or are organic compounds in the sense of chemistry (such as mellite). Moreover, living organisms often synthesize inorganic minerals (such as hydroxylapatite) that also occur in rocks. The concept of mineral is distinct from rock, which is any bulk solid geologic material that is relatively homogeneous at a large enough scale. A rock may consist of one type of mineral, or may be an aggregate of two or more different types of minerals, spacially segregated into distinct ...

Caldera
A caldera ( ) is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcano eruption. When large volumes of magma are erupted over a short time, structural support for the rock above the magma chamber is gone. The ground surface then collapses into the emptied or partially emptied magma chamber, leaving a large depression at the surface (from one to dozens of kilometers in diameter). Although sometimes described as a Volcanic crater, crater, the feature is actually a type of sinkhole, as it is formed through subsidence and collapse rather than an explosion or impact. Compared to the thousands of volcanic eruptions that occur each century, the formation of a caldera is a rare event, occurring only a few times per century. Only seven caldera-forming collapses are known to have occurred between 1911 and 2016. More recently, a caldera collapse occurred at Kīlauea, Hawaii in 2018. Etymology The term ''caldera'' comes from Spanish language, S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Danubian Hills
The Danubian Hills (Slovak: ''Podunajská pahorkatina''), also translated as Danubian Upland, is the north-eastern part of the Danubian Lowland in Slovakia often appearing as low rolling hills of prevalently eolic origin. It lies between the Danubian Flat and the Danube in the south, the Little Carpathians in the west and all the other Western Carpathians in the north and east. The border with the Danubian Flat runs approx. along the line Bratislava – Senec (Slovakia), Senec – Sereď – Nové Zámky – Patince. The area has varied rocks (clay, gravel, sands), which are covered by Quaternary sediments (loess) and very fertile soils (black and brown earths). Major towns of the area are Trnava, Topoľčany, Nitra, Levice, Dudince and Štúrovo. The Váh, Nitra River, Nitra, Žitava River, Žitava, Hron and Ipeľ rivers divide the area into the following 11 geomorphological parts (from the west to the east): *Trnavská pahorkatina (Trnava Hills) *Dolnovážska niva (Lower V ...
