Geology Of Svalbard
The geology of Svalbard encompasses the geological description of rock types found in Svalbard, and the associated tectonics and sedimentological history of soils and rocks. The geological exploration of Svalbard is an ongoing activity, and recent understandings may differ from earlier interpretations. Geological Basement Geological basement dated from Precambrian, Cambrian, Ordovician and Silurian, originally termed ''Hecla Hoek'', is found in three different provinces. The southwestern terrain comprises Prins Karls Forland, Oscar II Land, Nordenskiöld Land west of Grønfjorden and Wedel Jarlsberg Land . The northwestern terrain includes Haakon VII Land and Albert I Land. The northeastern terrain comprises Nordaustlandet and the northeastern parts of Spitsbergen. Devonian Devonian age sediments are exposed in Andrée Land (Svalbard), Andrée Land, James I Land and Dickson Land. Orogeny took place in late Devon.

Albert I Land
Albert I Land is the land area of the northwestern part of Spitsbergen, Svalbard. It is bordered by Haakon VII Land to the southeast. To the northeast lies Raudfjorden and its inner branch, Klinckowströmfjorden, to the southeast Krossfjorden and its inner branch, Lilliehöökfjorden, to the west and north the Arctic Ocean. Albert I Land is part of Spitsbergen that was first observed by Willem Barentz in 1596. Currently uninhabited, several geographical names stem from the history of whaling in the area during the 17th century. The area is named after Albert I, Prince of Monaco Albert I (Albert Honoré Charles Grimaldi; 13 November 1848 – 26 June 1922) was Prince of Monaco from 10 September 1889 until his death in 1922. He devoted much of his life to oceanography, exploration and science. Alongside his expeditions, ..., in honor of his exploration of Spitsbergen, and in particular this area in 1898-1907.

Billefjorden
Billefjorden is the central fjord of the three branching from the innermost part of the Isfjord, Svalbard, Isfjorden to the northeast, in Svalbard, Norway. It is 30 km long and 5–8 km wide. Billefjorden lies between Dickson Land to the northwest and Bünsow Land in the southeast. Located on its northwestern shore is the former Russian coal mining community of Pyramiden (abandoned in 1998). To the northeast is Nordenskiöldbreen (Nordenskiöld Glacier). At its northeastern extreme is Adolf Bay. The fjord is named after the Netherlands, Dutch whaler Cornelius Claeszoon Bille, who is mentioned as being active in 1675 by the Dutch whaler Cornelius Gisbert Zorgdrager. Originally another bay (now known as Adventfjorden) had been labeled as ''Klass Billen Bay'', but Nils Christoffer Dunér, Dunér and Adolf Erik Nordenskiöld, Nordenskiöld moved it to its present location. The fjord is the site of the Billefjorden Fault Zone, which continues to the north and separates Svalba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Permian
The Permian ( ) is a geologic period and System (stratigraphy), stratigraphic system which spans 47 million years, from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.902 Mya. It is the sixth and last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the Perm Governorate, region of Perm in Russia. The Permian witnessed the diversification of the two groups of amniotes, the synapsids and the Sauropsida, sauropsids (reptiles). The world at the time was dominated by the supercontinent Pangaea, which had formed due to the collision of Euramerica and Gondwana during the Carboniferous. Pangaea was surrounded by the superocean Panthalassa. The Carboniferous rainforest collapse left behind vast regions of desert within the continental interior. Amniotes, which could better cope with these ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carboniferous
The Carboniferous ( ) is a Geologic time scale, geologic period and System (stratigraphy), system of the Paleozoic era (geology), era that spans 60 million years, from the end of the Devonian Period Ma (million years ago) to the beginning of the Permian Period, Ma. It is the fifth and penultimate period of the Paleozoic era and the fifth period of the Phanerozoic eon (geology), eon. In North America, the Carboniferous is often treated as two separate geological periods, the earlier Mississippian (geology), Mississippian and the later Pennsylvanian (geology), Pennsylvanian. The name ''Carboniferous'' means "coal-bearing", from the Latin ("coal") and ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern "system" names, it was coined by geologists William Conybeare (geologist), William Conybeare and William Phillips (geologist), William Phillips in 1822, based on a study of the British rock succession. Carboniferous is the per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orogeny
Orogeny () is a mountain-mountain formation, building process that takes place at a convergent boundary, convergent plate margin when plate motion compresses the margin. An or develops as the compressed plate crumples and is tectonic uplift, uplifted to form one or more mountain ranges. This involves a series of geological processes collectively called orogenesis. These include both structural deformation (physics), deformation of existing continental crust and the creation of new continental crust through volcanism. Magma rising in the orogen carries less dense material upwards while leaving more dense material behind, resulting in compositional differentiation of Earth's lithosphere (crust (geology), crust and uppermost mantle (geology), mantle). A synorogenic (or synkinematic) process or event is one that occurs during an orogeny. The word ''orogeny'' comes . Although it was used before him, the American geologist Grove Karl Gilbert, G. K. Gilbert used the term in 1890 to me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Devonian
The Devonian ( ) is a period (geology), geologic period and system (stratigraphy), system of the Paleozoic era (geology), era during the Phanerozoic eon (geology), eon, spanning 60.3 million years from the end of the preceding Silurian period at million years ago (Megaannum, Ma), to the beginning of the succeeding Carboniferous period at Ma. It is the fourth period of both the Paleozoic and the Phanerozoic. It is named after Devon, South West England, where rocks from this period were first studied. The first significant evolutionary radiation of history of life#Colonization of land, life on land occurred during the Devonian, as free-spore, sporing land plants (pteridophytes) began to spread across dry land, forming extensive coal forests which covered the continents. By the middle of the Devonian, several groups of vascular plants had evolved leaf, leaves and true roots, and by the end of the period the first seed-bearing plants (Pteridospermatophyta, pteridospermatophyt ...
