Marble
Marble is a metamorphic rock consisting of carbonate minerals (most commonly calcite (CaCO3) or Dolomite (mineral), dolomite (CaMg(CO3)2) that have recrystallized under the influence of heat and pressure. It has a crystalline texture, and is typically not Foliation (geology), foliated (Layered intrusion, layered), although there are exceptions. In geology, the term ''marble'' refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. The extraction of marble is performed by quarrying. Marble production is dominated by four countries: China, Italy, India and Spain, which account for almost half of world production of marble and decorative stone. Because of its high hardness and strong wear resistance, and because it will not be deformed by temperature, marble is often used in Marble sculpture, sculpture and construction. Etymology The word "marble" derives from the Ancient Greek (), from (), "crystalline rock, shin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karst Cave
Karst () is a topography formed from the dissolution of soluble carbonate rocks such as limestone and dolomite. It is characterized by features like poljes above and drainage systems with sinkholes and caves underground. There is some evidence that karst may occur in more weathering-resistant rocks such as quartzite given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. In regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German in the late 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nordland
Nordland (; , , , ) is one of the three northernmost Counties of Norway, counties in Norway in the Northern Norway region, bordering Troms in the north, Trøndelag in the south, Norrbotten County in Sweden to the east, Västerbotten County to the south-east, and the Atlantic Ocean (Norwegian Sea) to the west. The county was formerly known as ''Nordlandene amt''. The county administration is in the Bodø (town), town of Bodø. The remote Arctic island of Jan Mayen has been administered from Nordland since 1995. In the southern part of the county is Vega Municipality, Vega, listed on the UNESCO World Heritage Site list. Districts The county is divided into traditional districts. These are Helgeland in the south (south of the Arctic Circle), Salten in the centre, and Ofoten in the north-east. In the north-west lie the archipelagoes of Lofoten and Vesterålen. Geography Nordland is located along the northwestern coast of the Scandinavian Peninsula in Northern Norway. Due to t ...

Store Norske Leksikon
The ''Great Norwegian Encyclopedia'' (, abbreviated ''SNL'') is a Norwegian-language online encyclopedia. It has several subdivisions, including the Norsk biografisk leksikon. The online encyclopedia is among the most-read Norwegian published sites, with up to 3.5 million unique visitors per month. Paper editions (1978–2007) The ''SNL'' was created in 1978, when the two publishing houses Aschehoug and Gyldendal merged their encyclopedias and created the company Kunnskapsforlaget. Up until 1978 the two publishing houses of Aschehoug and Gyldendal, Norway's two largest, had published ' and ', respectively. The respective first editions were published in 1906–1913 (Aschehoug) and 1933–1934 (Gyldendal). The slump in sales of paper-based encyclopedias around the turn of the 21st century hit Kunnskapsforlaget hard, but a fourth edition of the paper encyclopedia was secured by a grant of ten million Norwegian kroner from the foundation Fritt Ord in 2003.

Caves Of Norway
Caves or caverns are natural voids under the Earth's surface. Caves often form by the weathering of rock and often extend deep underground. Exogene caves are smaller openings that extend a relatively short distance underground (such as rock shelters). Caves which extend further underground than the opening is wide are called endogene caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorganisms, pressure, and atmospheric influences. Isotopic dating techniques can be applied to cave sediments, to determine the time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
