Vitosha Mountains
Vitosha ( bg, Витоша ), the ancient ''Scomius'' or ''Scombrus'', is a mountain massif, on the outskirts of Sofia, the capital of Bulgaria. Vitosha is one of the symbols of Sofia and the closest site for hiking, alpinism and skiing. Convenient bus lines and rope ways render the mountain easily accessible. Vitosha has the outlines of an enormous dome. The territory of the mountain includes Vitosha nature park that encompasses the best known and most frequently visited parts. The foothills of Vitosha shelter resort quarters of Sofia; Knyazhevo quarter has mineral springs. Vitosha is the oldest nature park in the Balkans. The mountain emerged as a result of volcanic activity and has been subsequently shaped by the slow folding of the granite rock layers and a series of gradual uplifts of the area. It appears dome shaped at first sight, but the mountain, 19 km long by 17 km wide, actually consists of concentric denudational plateaus rising in tiers one above the other ...

Massif
In geology, a massif ( or ) is a section of a planet's crust that is demarcated by faults or flexures. In the movement of the crust, a massif tends to retain its internal structure while being displaced as a whole. The term also refers to a group of mountains formed by such a structure. In mountaineering and climbing literature, a massif is frequently used to denote the main mass of an individual mountain. The massif is a smaller structural unit of the crust than a tectonic plate, and is considered the fourth-largest driving force in geomorphology. The word is taken from French (in which the word also means "massive"), where it is used to refer a large mountain mass or compact group of connected mountains forming an independent portion of a range. One of the most notable European examples of a massif is the Massif Central of the Auvergne region of France. The Face on Mars is an example of an extraterrestrial massif. Massifs may also form underwater, as with the Atlanti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Duhlata
Duhlata ( bg, Духлата) is a cave situated in Vitosha mountain, western Bulgaria. With a total length of 18,200 m, Duhlata is the longest cave in the country. It was declared a natural monument in 1962. The cave is home to six species of bats. Location Duhlata is situated in the south-western area of Vitosha on the left bank of the river Struma near the village of Bosnek, Pernik Province. The entrance of the cave is located at the very road between Bosnek and Chuypetlovo. Description The name of the cave originated from the sounds of the wind through its entrance, from Bulgarian ''духам'' (transl. ''duham''), meaning ''to whistle''. Duhlata is 18,200 m long and 53 m deep. The cave is well studied and mapped and boasts great diversity of speleothems. Duhlata is one of the most complex cave systems in Bulgaria and was created by underground currents of the Struma River. It is a maze of tunnels, galleries, underground lakes, waterfalls and sinter formation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Caves In Bulgaria
The list caves in Bulgaria, as of 2002, includes around 4,500 underground formations. The earliest written records about the caves in Bulgaria are found in the manuscripts of the 17th century Bulgarian National Revival figure and historian Petar Bogdan. The first Bulgarian speleological society was established in 1929. The caves in the country are inhabited by more than 700 invertebrate species and 32 of the 37 species of bats found in Europe. The longest caves in Bulgaria are Duhlata (18,200 m) and Orlova Chuka (13,437 m). The first show cave is Bacho Kiro, inaugurated in 1937. Nowadays, there are 10 tourist caves accessible to the public for guided visits in Bulgaria.

Laccolith
A laccolith is a body of intrusive rock with a dome-shaped upper surface and a level base, fed by a conduit from below. A laccolith forms when magma (molten rock) rising through the Earth's crust begins to spread out horizontally, prying apart the host rock strata. The pressure of the magma is high enough that the overlying strata are forced upward, giving the laccolith its dome-like form. Over time, erosion can expose the solidified laccolith, which is typically more resistant to weathering than the host rock. The exposed laccolith then forms a hill or mountain. The Henry Mountains of Utah, US, are an example of a mountain range composed of exposed laccoliths. It was here that geologist Grove Karl Gilbert carried out pioneering field work on this type of intrusion. Laccolith mountains have since been identified in many other parts of the world.

Sedimentary Rock
Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus (minerals) or biological detritus (organic matter). The geological detritus originated from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or mass movement, which are called agents of denudation. Biological detritus was formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies (marine snow). Sedimentation may also occur as dissolved minerals precipitate from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pluton
In geology, an igneous intrusion (or intrusive body or simply intrusion) is a body of intrusive igneous rock that forms by crystallization of magma slowly cooling below the surface of the Earth. Intrusions have a wide variety of forms and compositions, illustrated by examples like the Palisades Sill of New York and New Jersey; the Henry Mountains of Utah; the Bushveld Igneous Complex of South Africa; Shiprock in New Mexico; the Ardnamurchan intrusion in Scotland; and the Sierra Nevada Batholith of California. Because the solid country rock into which magma intrudes is an excellent insulator, cooling of the magma is extremely slow, and intrusive igneous rock is coarse-grained (phaneritic). Intrusive igneous rocks are classified separately from extrusive igneous rocks, generally on the basis of their mineral content. The relative amounts of quartz, alkali feldspar, plagioclase, and feldspathoid is particularly important in classifying intrusive igneous rocks. Intrusions ...

Sheet Intrusion
A sheet intrusion, or tabular intrusion, is a planar sheet of roughly the same thickness, that forms inside a pre-existing rock.Essentials of Geology, 3rd Ed, Stephen Marshak When it cuts into another unlayered mass, or across layers, it is called a " dike". When it is formed between layers in a layered rock mass, it is called a "sill". An igneous sheet intrusion is formed where a mass of molten magma takes advantage of a pre-existing linear feature in a host rock, such as a long rupture or fault, and forces its way into these spaces. Thus the magma, intruded between existing rocks, solidifies into large thin sheets of igneous rock. They are among the most extensive igneous features on Earth, in the form of dikes, laccolith A laccolith is a body of intrusive rock with a dome-shaped upper surface and a level base, fed by a conduit from below.

Greben (mountain)
Greben (Cyrillic: Гребен, meaning "ridge" or literally "comb") is a mountain in southeastern Serbia, with a small section of the southwestern ridge in Bulgaria. It is named after a large karst ridge that runs along its spine. Greben rises near the village of Poganovo in Serbia, in the municipality of Dimitrovgrad, and extends southeast towards the Bulgarian village of Vrabcha. Prior to the Treaty of Neuilly of 1919, after the First World War, the area was part of Bulgaria. Its highest peak ''Beženište'' (or ''Dziglina livada'') stands at an elevation of 1,338 meters above sea level. The highest peak that falls within Bulgaria is ''Dragovski kamak'' (Драговски камък), at 1,118 m. Due to the characteristic pyramidal shape of its north face, Dragovski kamak is referred to as the "Matterhorn of Tran". With nearby Vlaška planina, Greben forms the attractive canyon (''Poganovsko ždrelo'') of the Jerma (Erma) river. Greben Hill Greben Hill ( bg, ...
