Krásnohorská Cave
Krásnohorská Cave ( sk, Krásnohorská Jaskyňa) is a karst cave situated at the northern foot of the Silická planina Plain, in the Slovak Karst, 6.5 km southeast of Rožňava, in Slovakia. With unique natural decorations of bizarre shapes and unusual structure composed almost entirely of calcium, it is currently listed by the Guinness Book of Records as the cave containing the largest stalagmite in existence, generally accepted as being about in diameter and in height. It grows significantly in volume every year as the incessant drips solidify. The length of the cave is to and it represents the end of the cave system underground stream Buzgó. Description Part of the cave from the entrance to the Hall of Giants (''Sieň obrov'') is formed in dolomite and dolomitic limestones with impressive limestone layers. The back parts of the cave, like the Pearl Passage (''Chodba perál''), the Great Hall (''Veľká sieň''), and the Mirror Hall (''Zrkadlová sieň''), are loc ...

Karst
Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, 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 19th century, which entered German much earlier ...

Slovak Karst
The Slovak Karst ( sk, Slovenský kras) is one of the mountain ranges of the Slovenské Rudohorie Mountains in the Carpathians in southern Slovakia. It consists of a complex of huge karst plains and plateaus. Since 1973 it has been a protected landscape area. On 1 March 2002 Slovak Karst National Park was declared. It is also a UNESCO Biosphere Reserve and part of it forms UNESCO World Heritage site Caves of Aggtelek Karst and Slovak Karst. Characteristics The highest peak is Jelení vrch at 947 m AMSL. Important rivers are the Slaná (Sajó), the Štítnik and the Turňa. The Slovak Karst lies in the north temperate zone and has a continental climate with four distinct seasons. The area is composed of several layers of Mesozoic limestone and dolomite, beneath which there is non-permeable sandstone, limestone and slate. The plains are covered by oak-hornbeam forests, the hills by oak forests and the karst pits by spruce forests. Beech forests are in the northern parts. ...

Rožňava
Rožňava ( hu, Rozsnyó, german: Rosenau, Latin: ''Rosnavia'') is a town in Slovakia, approximately by road from Košice in the Košice Region, and has a population of 19,182. The town is an economic and tourist centre of the Gemer. Rožňava is now a popular tourist attraction with a beautiful historic town centre. The town is an episcopal seat. It has above all food, textile and remnants of mining industries. History Archaeological finds show that the region was densely settled by miners as early as around 1200. The first written mention stems from 1291, the royal free town status from 1410. The Roman Catholic diocese of Rozsnyó was founded in 1776. In the Middle Ages, Rozsnyó was a prosperous mining town for gold, silver, and iron. Mining activities stagnated from the 16th century (when territories to the south of the town were conquered by Ottoman Turks). Mining - this time mainly of iron ore - was renewed around 1800 and was present in the town throughout the 20th ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slovakia
Slovakia (; sk, Slovensko ), officially the Slovak Republic ( sk, Slovenská republika, links=no ), is a landlocked country in Central Europe. It is bordered by Poland to the north, Ukraine to the east, Hungary to the south, Austria to the southwest, and the Czech Republic to the northwest. Slovakia's mostly mountainous territory spans about , with a population of over 5.4 million. The capital and largest city is Bratislava, while the second largest city is Košice. The Slavs arrived in the territory of present-day Slovakia in the fifth and sixth centuries. In the seventh century, they played a significant role in the creation of Samo's Empire. In the ninth century, they established the Principality of Nitra, which was later conquered by the Principality of Moravia to establish Great Moravia. In the 10th century, after the dissolution of Great Moravia, the territory was integrated into the Principality of Hungary, which then became the Kingdom of Hungary in 1000. In 1241 a ...

Calcium
Calcium is a chemical element with the symbol Ca and atomic number 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium. It is the fifth most abundant element in Earth's crust, and the third most abundant metal, after iron and aluminium. The most common calcium compound on Earth is calcium carbonate, found in limestone and the fossilised remnants of early sea life; gypsum, anhydrite, fluorite, and apatite are also sources of calcium. The name derives from Latin ''calx'' "lime", which was obtained from heating limestone. Some calcium compounds were known to the ancients, though their chemistry was unknown until the seventeenth century. Pure calcium was isolated in 1808 via electrolysis of its oxide by Humphry Davy, who named the element. Calcium compounds are widely used in many industries: in foods and pharma ...

Guinness Book Of Records
''Guinness World Records'', known from its inception in 1955 until 1999 as ''The Guinness Book of Records'' and in previous United States editions as ''The Guinness Book of World Records'', is a reference book published annually, listing world records both of human achievements and the extremes of the natural world. The brainchild of Sir Hugh Beaver, the book was co-founded by twin brothers Norris and Ross McWhirter in Fleet Street, London, in August 1955. The first edition topped the best-seller list in the United Kingdom by Christmas 1955. The following year the book was launched internationally, and as of the 2022 edition, it is now in its 67th year of publication, published in 100 countries and 23 languages, and maintains over 53,000 records in its database. The international franchise has extended beyond print to include television series and museums. The popularity of the franchise has resulted in ''Guinness World Records'' becoming the primary international authority ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stalagmite
A stalagmite (, ; from the Greek , from , "dropping, trickling") is a type of rock formation that rises from the floor of a cave due to the accumulation of material deposited on the floor from ceiling drippings. Stalagmites are typically composed of calcium carbonate, but may consist of lava, mud, peat, pitch, sand, sinter, and amberat (crystallized urine of pack rats). The corresponding formation hanging down from the ceiling of a cave is a stalactite. Mnemonics have been developed for which word refers to which type of formation; one is that ''stalactite'' has a C for "ceiling", and ''stalagmite'' has a G for "ground", another is that, as with ants in the pants, the mites go up and the tights (tites) come down. Formation and type Limestone stalagmites The most common stalagmites are speleothems, which usually form in limestone caves. Stalagmite formation occurs only under certain pH conditions within the cavern. They form through deposition of calcium carbonate ...

Dolomite (rock)
Dolomite (also known as dolomite rock, dolostone or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO3)2. It occurs widely, often in association with limestone and evaporites, though it is less abundant than limestone and rare in Cenozoic rock beds (beds less than about 66 million years in age). The first geologist to distinguish dolomite rock from limestone was Belsazar Hacquet in 1778. Most dolomite was formed as a magnesium replacement of limestone or of lime mud before lithification. The geological process of conversion of calcite to dolomite is known as dolomitization and any intermediate product is known as dolomitic limestone. The "dolomite problem" refers to the vast worldwide depositions of dolomite in the past geologic record in contrast to the limited amounts of dolomite formed in modern times. Recent research has revealed sulfate-reducing bacteria living in anoxic conditions precipitate dolomite which ind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
