Upper Jurassic
The Late Jurassic is the third epoch of the Jurassic Period, and it spans the geologic time from 163.5 ± 1.0 to 145.0 ± 0.8 million years ago (Ma), which is preserved in Upper Jurassic strata.Owen 1987. In European lithostratigraphy, the name "Malm" indicates rocks of Late Jurassic age. In the past, ''Malm'' was also used to indicate the unit of geological time, but this usage is now discouraged to make a clear distinction between lithostratigraphic and geochronologic/chronostratigraphic units. Subdivisions The Late Jurassic is divided into three ages, which correspond with the three (faunal) stages of Upper Jurassic rock: Paleogeography During the Late Jurassic Epoch, Pangaea broke up into two supercontinents, Laurasia to the north, and Gondwana to the south. The result of this break-up was the spawning of the Atlantic Ocean. However, at this time, the Atlantic Ocean was relatively narrow. Life forms of the epoch This epoch is well known for many famous types of dinosaurs, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexander Kruber
Alexander Alexandrovich Kruber (russian: Александр Александрович Крубер; – December 15, 1941) was a Soviet geographer, professor, the founder of the Russian and Soviet karstology. Alexander Kruber was born in Istra (formerly Voskresensk), Russia. He graduated from the Moscow University in 1897. He became chairman of the Geography Department of the Moscow University in 1919 and director of the Scientific Research Institute of Geography during 1923-1927. Since 1927 he could no longer work due to grave health problems. He studied karst structures of the East European Plain, Crimea, and Caucasus.

Voronya Cave
Krubera Cave ( ab, Ӡоу Аҳаҧы, ka, კრუბერის გამოქვაბული or კრუბერის ღრმული, tr; also known as Voronya Cave, sometimes spelled Voronja Cave) is the second-deepest-known cave on Earth, after the Veryovkina Cave.

Veryovkina Cave
Veryovkina Cave (also spelled Verëvkina Cave, , ) is a cave in Abkhazia, a breakaway region of Georgia. At 2,212 meters (7,257 ft) deep, it is the deepest-known cave on Earth. Its entrance is 2,285 metres (7,497 ft) above sea level. The entrance of the cave has a cross section of 3 m × 4 m (9.8 ft × 13.1 ft), and is located in the Arabika Massif in the Gagra Mountain Range of the Western Caucasus, on the pass between the Krepost and Zont mountains, closer to the slopes of Mount Krepost. The depth of the entrance shaft is 32 metres (105 ft). Naming In 1968, the cave was assigned the name S-115, which was later replaced by P1-7, and in 1986 it was renamed after caver and cave diver Alexander Verëvkin. Verëvkin died in 1983 while exploring a siphon in the cave Su-Akan, located in the Sary-Tala massif, now Kabardino-Balkaria, Russia. Discovery * The entrance is located in the Gagra District of Abkhazia, Georgia. * 1968: the cave was discovered by cavers from Krasnoyarsk ...

Black Sea
The Black Sea is a marginal mediterranean sea of the Atlantic Ocean lying between Europe and Asia, east of the Balkans, south of the East European Plain, west of the Caucasus, and north of Anatolia. It is bounded by Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine. The Black Sea is supplied by major rivers, principally the Danube, Dnieper, and Don. Consequently, while six countries have a coastline on the sea, its drainage basin includes parts of 24 countries in Europe. The Black Sea covers (not including the Sea of Azov), has a maximum depth of , and a volume of . Most of its coasts ascend rapidly. These rises are the Pontic Mountains to the south, bar the southwest-facing peninsulas, the Caucasus Mountains to the east, and the Crimean Mountains to the mid-north. In the west, the coast is generally small floodplains below foothills such as the Strandzha; Cape Emine, a dwindling of the east end of the Balkan Mountains; and the Dobruja Plateau considerably farth ...

Strike And Dip
Strike and dip is a measurement convention used to describe the orientation, or attitude, of a planar geologic feature. A feature's strike is the azimuth of an imagined horizontal line across the plane, and its dip is the angle of inclination measured downward from horizontal. They are used together to measure and document a structure's characteristics for study or for use on a geologic map. A feature's orientation can also be represented by dip and dip direction, using the azimuth of the dip rather than the strike value. Linear features are similarly measured with trend and plunge, where "trend" is analogous to dip direction and "plunge" is the dip angle. Strike and dip are measured using a compass and a clinometer. A compass is used to measure the feature's strike by holding the compass horizontally against the feature. A clinometer measures the features dip by recording the inclination perpendicular to the strike. These can be done separately, or together using a tool such a ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...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 ...

Gagra
Gagra ( ka, გაგრა; Abkhaz and Russian: Гагра) is a town in Abkhazia/Georgia, sprawling for 5 km on the northeast coast of the Black Sea, at the foot of the Caucasus Mountains. Its subtropical climate made Gagra a popular health resort in Imperial Russian and Soviet times. It had a population of 26,636 in 1989, but this has fallen considerably due to the ethnic cleansing of Georgians in Abkhazia and other demographic shifts during and after the War in Abkhazia (1992–93). Gagra is the centre of the district of the same name. It is located in the western part of Region of Abkhazia, and river Psou serves as a border with Krasnodar Krai of Russia. Etymology According to some Georgian scholars, ''Gagra'' is derived from ''Gakra'' meaning "walnut" in the Svan language. According to the Soviet writer Bondaryev, the name of the city originates from the local ''Gagaa'' clan. According to Professor V. Kvarchija, Gagra ( Gagra and the Abkhazian capital Sukhumi wer ...
