Hidaka Mountains
is a mountain range in southeastern Hokkaido, Japan. It runs from Mount Sahoro or Karikachi Pass in central Hokkaidō south, running into the sea at Cape Erimo. It consists of folded mountains that range from in height. Mount Poroshiri is the highest at . The Hidaka Mountains separate the subprefectures of Hidaka and Tokachi. Most of the range lies in the Hidaka-sanmyaku Erimo Quasi-National Park (日高山脈襟裳国定公園, ''Hidaka-sanmyaku Erimo Kokutei-kōen''). Since the mountain range lies so far north, the alpine climate zone lies at a lower altitude. Geology The Hidaka Mountains formed in the late Quaternary as part of the outer arc of the western end of the Kuril Island Arc. They were formed by the uplift resulting from the collision with the Kuril arc and the Northeast Japan Arc. The Hidaka mountains no longer appear to be uplifting. The western end of the range is high P/T metamorphoseed Jurassic accretionary complex as part of the Kamuikotan belt. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hokkaido
is Japan's second largest island and comprises the largest and northernmost prefecture, making up its own region. The Tsugaru Strait separates Hokkaidō from Honshu; the two islands are connected by the undersea railway Seikan Tunnel. The largest city on Hokkaidō is its capital, Sapporo, which is also its only ordinance-designated city. Sakhalin lies about 43 kilometers (26 mi) to the north of Hokkaidō, and to the east and northeast are the Kuril Islands, which are administered by Russia, though the four most southerly are claimed by Japan. Hokkaidō was formerly known as ''Ezo'', ''Yezo'', ''Yeso'', or ''Yesso''. Nussbaum, Louis-Frédéric. (2005). "Hokkaidō" in Although there were Japanese settlers who ruled the southern tip of the island since the 16th century, Hokkaido was considered foreign territory that was inhabited by the indigenous people of the island, known as the Ainu people. While geographers such as Mogami Tokunai and Mamiya Rinzō explored the isla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sedimentary
Sedimentary rocks are types of rock (geology), rock that are formed by the accumulation or deposition of mineral or organic matter, organic particles at Earth#Surface, Earth's surface, followed by cementation (geology), 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 detritus (geology), geological detritus (minerals) or detritus, 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 wasting, 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 ...

Accretionary Wedge
An accretionary wedge or accretionary prism forms from sediments accreted onto the non-subducting tectonic plate at a convergent plate boundary. Most of the material in the accretionary wedge consists of marine sediments scraped off from the downgoing slab of oceanic crust, but in some cases the wedge includes the erosional products of volcanic island arcs formed on the overriding plate. An accretionary complex is a current (in modern use) or former accretionary wedge. Accretionary complexes are typically made up of a mix of turbidites of terrestrial material, basalts from the ocean floor, and pelagic and hemipelagic sediments. For example, most of the geological basement of Japan is made up of accretionary complexes. Materials within an accretionary wedge Accretionary wedges and accreted terranes are not equivalent to tectonic plates, but rather are associated with tectonic plates and accrete as a result of tectonic collision. Materials incorporated in accretionary wedges inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jurassic
The Jurassic ( ) is a Geological period, geologic period and System (stratigraphy), stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya. The Jurassic constitutes the middle period of the Mesozoic, Mesozoic Era and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic magmatic province, Central Atlantic Magmatic Province. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread Anoxic event, oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar, Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metamorphism
Metamorphism is the transformation of existing rock (the protolith) to rock with a different mineral composition or texture. Metamorphism takes place at temperatures in excess of , and often also at elevated pressure or in the presence of chemically active fluids, but the rock remains mostly solid during the transformation. Metamorphism is distinct from weathering or diagenesis, which are changes that take place at or just beneath Earth's surface. Various forms of metamorphism exist, including regional, contact, hydrothermal, shock, and dynamic metamorphism. These differ in the characteristic temperatures, pressures, and rate at which they take place and in the extent to which reactive fluids are involved. Metamorphism occurring at increasing pressure and temperature conditions is known as ''prograde metamorphism'', while decreasing temperature and pressure characterize ''retrograde metamorphism''. Metamorphic petrology is the study of metamorphism. Metamorphic petrologists re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kuril Islands
The Kuril Islands or Kurile Islands (; rus, Кури́льские острова́, r=Kuril'skiye ostrova, p=kʊˈrʲilʲskʲɪjə ɐstrɐˈva; Japanese: or ) are a volcanic archipelago currently administered as part of Sakhalin Oblast in the Russian Far East. It stretches approximately northeast from Hokkaido in Japan to Kamchatka Peninsula in Russia separating the Sea of Okhotsk from the north Pacific Ocean. There are 56 islands and many minor rocks. The Kuril Islands consist of the Greater Kuril Chain and the Lesser Kuril Chain. They cover an area of around , with a population of roughly 20,000. The islands have been under Russian administration since their 1945 invasion as the Soviet Union towards the end of World War II. Japan claims the four southernmost islands, including two of the three largest ( Iturup and Kunashir), as part of its territory, as well as Shikotan and the Habomai islets, which has led to the ongoing Kuril Islands dispute. The disputed islands are k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Subprefectures Of Japan
are a Japanese form of self-government which focuses on local issues below the prefectural level. It acts as part of the greater administration of the state and as part of a self-government system.Imperial Japanese Commission to the Louisiana Purchase Exposition. (1903)''Japan in the beginning of the 20th century'', p. 80 History They were given a definite form in 1878 (''Meiji 11'').Imperial Japanese Commissionp. 81 The Meiji government established the as an administrative unit. In 1888 (''Meiji 21''), the sub-prefecture as a form of self-government was officially recognized as more general than civic corporations like cities, towns and villages. Certain prefectures of Japan are now, or once were, divided into subprefectures. The subprefecture is the jurisdiction surrounding a "branch office" of the prefectural government. Normally, the area of a subprefecture consists of a few to a dozen cities, towns, and/or villages. Subprefectures are formed to provide services of t ...

Cape Erimo
is a Cape (geography), cape in Hokkaidō, located at . It is the de facto southern tip of Hidaka Mountains. Description Hot and cold fronts meet near the cape, thus creating a dense mist which covers the cape for more than 100 days a year. Wind blows here with the speed of for almost 300 days a year. Every year, more than 400,000 tourists visit Cape Erimo. Rare species of Kuril Seals live there. Asteroid The main-belt asteroid 5331 Erimomisaki, discovered by amateur astronomers Kin Endate and Kazuro Watanabe in 1990, was named after Cape Erimo.
