Åshima (Aomori)
is a rocky island off the northern coast of Natsudomari Peninsula in Mutsu Bay. The island is a part of Hiranai in Aomori Prefecture. The island has of coastline and an area of . It is a part of the prefecture-maintained, Asamushi-Natsudomari Prefectural Natural Park. Geography The island lies only 200 meters north of Natsudomari Peninsula in Mutsu Bay. It was once possible to walk from the island to the peninsula at low-tide, but erosion made this impossible over time. The island is forested on its southern half, while its northern half is covered in grassland. The grassland was used for pastoral farming before the island was designated a natural park. Geology Åshima is a sill that was formed underground when a volcano dominated the landscape of Natsudomari Peninsula during the Miocene. The rock of the Åshima sill is made up of dacite and rhyolite. History During the time the Tsugaru clan ruled the area, the island was known as , reflecting that it was viewed as a ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aomori Prefecture
is a prefecture of Japan in the TÅhoku region. The prefecture's capital, largest city, and namesake is the city of Aomori. Aomori is the northernmost prefecture on Japan's main island, Honshu, and is bordered by the Pacific Ocean to the east, Iwate Prefecture to the southeast, Akita Prefecture to the southwest, the Sea of Japan to the west, and Hokkaido across the Tsugaru Strait to the north.

( ain, ãã©ãã£, piranay) is a town located in Aomori Prefecture, Japan and a part of the Aomori metropolitan area. , the town had an estimated population of 10,460 in 4,860 households, and a population density of 48 persons per km². It is the most heavily populated town in Higashitsugaru District. The total area of the town is .

The Ainu words for and are said to be the original name of the area, due to its geography as a river valley in the interior of the mountainous Natsudomari Peninsula. However, the current Japanese pronunciation and meaning of the town's name, is descriptive of the valley, but is based on the flat area inside of the mountains or the bay that surrounds it.

Natsudomari Peninsula
is a peninsula on the northern end of the Japanese island, HonshÅ«, that stretches north into Mutsu Bay. Administratively the area is a part of Aomori Prefecture, and the bulk of the area falls within the jurisdiction of the town of Hiranai, with Aomori city on the western periphery of the landform. The peninsula has several small fishing communities scattered around the coastline, but most of the area's people live in the river valley that demarcates the southern boundary of the peninsula. The peninsula is notably an attractive nesting place for Siberian tundra swan. Geography The Natsudomari Peninsula is bordered by Mutsu Bay to the east and north and Aomori Bay to the west. The peninsula is connected to the mainland of HonshÅ« to the south. The Åu Mountain Range begins on the peninsula and continues to the Nasu Mountains at the northern boundary of the KantÅ region.

Pastoral Farming
Pastoral farming (also known in some regions as ranching, livestock farming or grazing) is aimed at producing livestock, rather than growing crops. Examples include dairy farming, raising beef cattle, and raising sheep for wool. In contrast, arable farming concentrates on crops rather than livestock. Finally, mixed farming incorporates livestock and crops on a single farm. Some mixed farmers grow crops purely as fodder for their livestock; some crop farmers grow fodder and sell it. In some cases (such as in Australia) pastoral farmers are known as ''graziers'', and in some cases ''pastoralists'' (in a use of the term different from traditional nomadic livestock cultures). Pastoral farming is a non-nomadic form of pastoralism in which the livestock farmer has some form of ownership of the land used, giving the farmer more economic incentive to improve the land. Unlike other pastoral systems, pastoral farmers are sedentary and do not change locations in search of fresh resources. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sill (geology)
In geology, a sill is a tabular sheet intrusion that has intruded between older layers of sedimentary rock, beds of volcanic lava or tuff, or along the direction of foliation in metamorphic rock. A ''sill'' is a ''concordant intrusive sheet'', meaning that a sill does not cut across preexisting rock beds. Stacking of sills builds a sill complex . and a large magma chamber at high magma flux. In contrast, a dike is a discordant intrusive sheet, which does cut across older rocks. Sills are fed by dikes, except in unusual locations where they form in nearly vertical beds attached directly to a magma source. The rocks must be brittle and fracture to create the planes along which the magma intrudes the parent rock bodies, whether this occurs along preexisting planes between sedimentary or volcanic beds or weakened planes related to foliation in metamorphic rock. These planes or weakened areas allow the intrusion of a thin sheet-like body of magma paralleling the existing bedding pla ...

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.

Dacite
Dacite () is a volcanic rock formed by rapid solidification of lava that is high in silica and low in alkali metal oxides. It has a fine-grained (aphanitic) to porphyritic texture and is intermediate in composition between andesite and rhyolite. It is composed predominantly of plagioclase feldspar and quartz. Dacite is relatively common, occurring in many tectonic settings. It is associated with andesite and rhyolite as part of the subalkaline volcanic rock, subalkaline tholeiite, tholeiitic and calc-alkaline magma series. Composition Dacite consists mostly of plagioclase feldspar and quartz with biotite, hornblende, and pyroxene (augite or enstatite). The quartz appears as rounded, corroded phenocrysts, or as an element of the ground-mass. The plagioclase in dacite ranges from oligoclase to andesine and labradorite. Sanidine occurs, although in small proportions, in some dacites, and when abundant gives rise to rocks that form rhyodacite, transitions to the rhyolites. The rel ...

Rhyolite
Rhyolite ( ) is the most silica-rich of volcanic rocks. It is generally glassy or fine-grained (aphanitic) in texture, but may be porphyritic, containing larger mineral crystals (phenocrysts) in an otherwise fine-grained groundmass. The mineral assemblage is predominantly quartz, sanidine, and plagioclase. It is the extrusive equivalent to granite. Rhyolitic magma is extremely viscous, due to its high silica content. This favors explosive eruptions over effusive eruptions, so this type of magma is more often erupted as pyroclastic rock than as lava flows. Rhyolitic ash-flow tuffs are among the most voluminous of continental igneous rock formations. Rhyolitic tuff has been extensively used for construction. Obsidian, which is rhyolitic volcanic glass, has been used for tools from prehistoric times to the present day because it can be shaped to an extremely sharp edge. Rhyolitic pumice finds use as an abrasive, in concrete, and as a soil amendment. Description Rhyolite i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
