Livezile, Alba
Livezile (until 1960 ''Cacova''; german: Laßlenkirch, hu, Úrháza) is a commune located in Alba County, Transylvania, Romania. It is composed of four villages: Izvoarele (''Bedellő''), Livezile, Poiana Aiudului (''Nyírmező''), and Vălișoara (''Torockógyertyános''). The commune is situated in the northern foothills of the Trascău Mountains, in the Apuseni mountain range. It lies on the banks of the Aiud River; its tributaries, the rivers Inzel and Rachiș, flow through Poiana Aiudului. Located in the northern part of the county, Livezile is at a distance of from the city of Aiud, and from the county seat, Alba Iulia. It is crossed by county road DJ107M, which connects Aiud to Iara, in Cluj County. The road passes through the nearby (''Cheile Vălișoarei'', or ''Cheile Aiudului''), which belong to the administrative territory of the commune. The gorges are long, wide, and high. The walls of the gorges house 27 small caves with shallow karst shapes: lapis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commune In Romania
A commune (''comună'' in Romanian language, Romanian) is the lowest level of administrative subdivision in Romania. There are 2,686 communes in Romania. The commune is the rural subdivision of a Counties of Romania, county. Urban areas, such as towns and cities within a county, are given the status of ''Cities in Romania, city'' or ''Municipality in Romania, municipality''. In principle, a commune can contain any size population, but in practice, when a commune becomes relatively urbanised and exceeds approximately 10,000 residents, it is usually granted city status. Although cities are on the same administrative level as communes, their local governments are structured in a way that gives them more power. Some urban or semi-urban areas of fewer than 10,000 inhabitants have also been given city status. Each commune is administered by a mayor (''primar'' in Romanian). A commune is made up of one or more villages which do not themselves have an administrative function. Communes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arch
An arch is a vertical curved structure that spans an elevated space and may or may not support the weight above it, or in case of a horizontal arch like an arch dam, the hydrostatic pressure against it. Arches may be synonymous with vaults, but a vault may be distinguished as a continuous arch forming a roof. Arches appeared as early as the 2nd millennium BC in Mesopotamian brick architecture, and their systematic use started with the ancient Romans, who were the first to apply the technique to a wide range of structures. Basic concepts An arch is a pure compression form. It can span a large area by resolving forces into compressive stresses, and thereby eliminating tensile stresses. This is sometimes denominated "arch action". As the forces in the arch are transferred to its base, the arch pushes outward at its base, denominated "thrust". As the rise, i. e. height, of the arch decreases the outward thrust increases. In order to preserve arch action and prevent collapse ...

Vault (architecture)
In architecture, a vault (French ''voûte'', from Italian ''volta'') is a self-supporting arched form, usually of stone or brick, serving to cover a space with a ceiling or roof. As in building an arch, a temporary support is needed while rings of voussoirs are constructed and the rings placed in position. Until the topmost voussoir, the keystone, is positioned, the vault is not self-supporting. Where timber is easily obtained, this temporary support is provided by centering consisting of a framed truss with a semicircular or segmental head, which supports the voussoirs until the ring of the whole arch is completed. Vault types Corbelled vaults, also called false vaults, with horizontally joined layers of stone have been documented since prehistoric times; in the 14th century BC from Mycenae. They were built regionally until modern times. The real vault construction with radially joined stones was already known to the Egyptians and Assyrians and was introduced into the buil ...

Lapis Lazuli
Lapis lazuli (; ), or lapis for short, is a deep-blue metamorphic rock used as a semi-precious stone that has been prized since antiquity for its intense color. As early as the 7th millennium BC, lapis lazuli was mined in the Sar-i Sang mines,David Bomford and Ashok Roy, ''A Closer Look- Colour'' (2009), National Gallery Company, London, () in Shortugai, and in other mines in Badakhshan province in northeast Afghanistan. Lapis lazuli artifacts, dated to 7570 BC, have been found at Bhirrana, which is the oldest site of Indus Valley civilisation. Lapis was highly valued by the Indus Valley Civilisation (7570–1900 BC). Lapis beads have been found at Neolithic burials in Mehrgarh, the Caucasus, and as far away as Mauritania. It was used in the funeral mask of Tutankhamun (1341–1323 BC). By the end of the Middle Ages, lapis lazuli began to be exported to Europe, where it was ground into powder and made into ultramarine, the finest and most expensive of all blue pigments. Ultra ...

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 ...

Canyon
A canyon (from ; archaic British English spelling: ''cañon''), or gorge, is a deep cleft between escarpments or cliffs resulting from weathering and the erosion, erosive activity of a river over geologic time scales. Rivers have a natural tendency to cut through underlying surfaces, eventually wearing away rock layers as sediments are removed downstream. A river bed will gradually reach a baseline elevation, which is the same elevation as the body of water into which the river drains. The processes of weathering and erosion will form canyons when the river's River source, headwaters and estuary are at significantly different elevations, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering. A canyon may also refer to a rift between two mountain peaks, such as those in ranges including the Rocky Mountains, the Alps, the Himalayas or the Andes. Usually, a river or stream carves out such splits between mountains. Examp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cluj County
Cluj County (; german: Kreis Klausenburg, hu, Kolozs megye) is a county ( județ) of Romania, in Transylvania. Its seat ( ro, Oraș reședință de județ) is Cluj-Napoca (german: Klausenburg). Name In Hungarian, it is known as ''Kolozs megye'', and in German as ''Kreis Klausenburg''. Under Kingdom of Hungary, a county with an identical name (Kolozs County, ro, Comitatul Cluj) existed since the 11th century.
