Detunatele
Detunatele is a site of columnar jointing in Alba County, Transylvania, Romania. ''Detunatele'' means lightning strike. The columns are made of hexagonal-shaped basalt and are tall on two peaks: Detunata Goală and Detunata Flocoasă (Barren Detunata and Shaggy Detunata). The two peaks are located in the Metaliferi Mountains Metaliferi Mountains ( ro, Munții Metaliferi; hu, Erdélyi-érchegység), meaning Ore Mountains, are in the Carpathian Mountain Range and are a division of the Apuseni Mountains.

Basalt Columns In Romania
Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flo ...

Columnar Jointing
Columnar jointing is a geological structure where sets of intersecting closely spaced fractures, referred to as Joint (geology), joints, result in the formation of a regular array of polygonal Prism (geometry), prisms, or columns. Columnar jointing occurs in many types of igneous rocks and forms as the rock cools and contracts. Columnar jointing can occur in cooling lava flows and ashflow tuffs (ignimbrites), as well as in some shallow intrusions. Columnar jointing also occurs rarely in sedimentary rocks if they have been heated by nearby hot magma. The columns can vary from 3 meters to a few centimeters in diameter, and can be as much as 30 meters tall. They are typically parallel and straight, but can also be curved and vary in diameter. An array of regular, straight, and larger-diameter columns is called a colonnade; an irregular, less-straight, and smaller-diameter array is termed an entablature. The number of sides of the individual columns can vary from 3 to 8, with 6 sides ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transylvania
Transylvania ( ro, Ardeal or ; hu, Erdély; german: Siebenbürgen) is a historical and cultural region in Central Europe, encompassing central Romania. To the east and south its natural border is the Carpathian Mountains, and to the west the Apuseni Mountains. Broader definitions of Transylvania also include the western and northwestern Romanian regions of Crișana and Maramureș, and occasionally Banat. Transylvania is known for the scenery of its Carpathian landscape and its rich history. It also contains Romania's second-largest city, Cluj-Napoca, and other iconic cities and towns such as Brașov, Sibiu, Târgu Mureș, Alba Iulia and Sighișoara. It is also the home of some of Romania's List of World Heritage Sites in Romania, UNESCO World Heritage Sites such as the villages with fortified churches in Transylvania, Villages with fortified churches, the Historic Centre of Sighișoara, the Dacian Fortresses of the Orăștie Mountains and the Rosia Montana Mining Cultural Landsc ...

Hexagonal Crystal Family
In crystallography, the hexagonal crystal family is one of the six crystal families, which includes two crystal systems (hexagonal and trigonal) and two lattice systems (hexagonal and rhombohedral). While commonly confused, the trigonal crystal system and the rhombohedral lattice system are not equivalent (see section crystal systems below). In particular, there are crystals that have trigonal symmetry but belong to the hexagonal lattice (such as α-quartz). The hexagonal crystal family consists of the 12 point groups such that at least one of their space groups has the hexagonal lattice as underlying lattice, and is the union of the hexagonal crystal system and the trigonal crystal system. There are 52 space groups associated with it, which are exactly those whose Bravais lattice is either hexagonal or rhombohedral. __TOC__ Lattice systems The hexagonal crystal family consists of two lattice systems: hexagonal and rhombohedral. Each lattice system consists of one Bravais la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Adevărul
''Adevărul'' (; meaning "The Truth", formerly spelled ''Adevĕrul'') is a Romanian daily newspaper, based in Bucharest. Founded in Iași, in 1871, and reestablished in 1888, in Bucharest, it was the main left-wing press venue to be published during the Romanian Kingdom's existence, adopting an independent pro- democratic position, advocating land reform, and demanding universal suffrage. Under its successive editors Alexandru Beldiman and Constantin Mille, it became noted for its virulent criticism of King Carol I. This stance developed into a republican and socialist agenda, which made ''Adevărul'' clash with the Kingdom's authorities on several occasions. As innovative publications which set up several local and international records during the early 20th century, ''Adevărul'' and its sister daily ''Dimineața'' competed for the top position with the right-wing ''Universul'' before and throughout the interwar period. In 1920, ''Adevărul'' also began publishing its prestigious ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Columnar Basalts
Epithelium or epithelial tissue is one of the four basic types of animal tissue, along with connective tissue, muscle tissue and nervous tissue. It is a thin, continuous, protective layer of compactly packed cells with a little intercellular matrix. Epithelial tissues line the outer surfaces of organs and blood vessels throughout the body, as well as the inner surfaces of cavities in many internal organs. An example is the epidermis, the outermost layer of the skin. There are three principal shapes of epithelial cell: squamous (scaly), columnar, and cuboidal. These can be arranged in a singular layer of cells as simple epithelium, either squamous, columnar, or cuboidal, or in layers of two or more cells deep as stratified (layered), or ''compound'', either squamous, columnar or cuboidal. In some tissues, a layer of columnar cells may appear to be stratified due to the placement of the nuclei. This sort of tissue is called pseudostratified. All glands are made up of epithelial ...

Geology Of Romania
The geology of Romania is structurally complex, with evidence of past crustal movements and the incorporation of different blocks or platforms to the edge of Europe, driving recent mountain building of the Carpathian Mountains. Romania is a country located at the crossroads of Central, Eastern, and Southeastern Europe. It borders the Black Sea to the southeast, Bulgaria to the south, Ukraine to the north, Hungary to the west, Serbia to the southwest, and Moldova to the east. Structural geology Geologists subdivide Romania into several structural groupings: *Scythian Platform: A platform spanning from eastern Romania to Crimea. Complex folding of Precambrian and Paleozoic basement rocks, slate, Ordovician sandstone, Silurian shale, and Devonian marl and sandstone. Platform cover rocks include Devonian limestone, Triassic basic detrital rocks, carbonates, Jurassic marl, and sand as well as Neogene shallow water sediments typical of the Carpathian Foreland. *Moesian Platform: Southern ...

Geography Of Alba County
Geography (from Greek: , ''geographia''. Combination of Greek words ‘Geo’ (The Earth) and ‘Graphien’ (to describe), literally "earth description") is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of Earth. The first recorded use of the word γεωγραφία was as a title of a book by Greek scholar Eratosthenes (276–194 BC). Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. One such concept, the first law of geography, proposed by Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." Geography has been called "the world discipline" and "the bridge between the human and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
