Geology Of Taiwan
The island of Taiwan was formed approximately 4 to 5 million years ago at a convergent boundary between the Philippine Sea Plate and the Eurasian Plate. In a boundary running the length of the island and continuing southwards, the Eurasian Plate is sliding under the Philippine Sea Plate. In the northeast of the island, the Philippine Sea Plate slides under the Eurasian Plate. Most of the island comprises a huge fault block tilted to the west. The island is active geologically, formed on a complex convergent boundary between the Yangtze Subplate of the Eurasian Plate to the west and north, the Okinawa Plate on the north-east, the Philippine Sea Plate on the east and south, and the Sunda Plate to the southwest. Subduction changes direction at Taiwan. The upper part of the crust on the island is primarily made up of a series of terranes, mostly old island arcs which have been forced together by the collision of the forerunners of the Eurasian Plate and the Philippine Se ...

Hai'an Range
The Coastal Mountain Range, also known as the Hai'an Range (), is a mountain range situated on the eastern coast of the island of Taiwan, and spans the border between Hualien and Taitung Counties. The Coastal Mountain Range is the northern portion of the Luzon Arc but do not present current volcanic activity. Its geology is mainly composed of a Miocene volcanic basement covered by a thick (ca.4-6km) sedimentary pile of deep to shallow marine clastic deposits mostly derived from the adjacent Central Range mountains to the west. The Huadong Valley, the result of the collision of two tectonic plates, is at the west end of the range, and the tallest peak of the range is Xingangshan (新港山), which stands tall. Currently those peaks are still rising with an annual speed of 3 mm. The Hai'an Range is also converging with Central Mountain Range with an average speed of 2.3 cm per year. There are several small basins located around the range, the largest of which is T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glaucophane
Glaucophane is a mineral and a mineral group belonging to the sodic amphibole supergroup of the double chain inosilicates, with the chemical formula Na2(Mg3Al2)Si8O22(OH)2. Glaucophane crystallizes in the monoclinic system. Name Glaucophane is named for its typical blue color. In Greek, ''glaucophane'' means "blue appearing". As the major mineral component, it is glaucophane's color that gives the "blueschist" metamorphic rock type its name. Characteristics The blue color is very diagnostic for this species. Glaucophane, along with the closely related mineral riebeckite, to which it forms a series with, and their intermediate crossite, are the only well known amphiboles that are commonly blue. Glaucophane forms a solid solution series with ferroglaucophane (). Glaucophane is the magnesium-rich endmember and ferroglaucophane is the iron-rich endmember. Ferroglaucophane is similar to glaucophane but is slightly denser and hence increased specific gravity. The two endmembers a ...

Greenschist
Greenschists are metamorphic rocks that formed under the lowest temperatures and pressures usually produced by regional metamorphism, typically and 2–10 kilobars (). Greenschists commonly have an abundance of green minerals such as Chlorite group, chlorite, Serpentine subgroup, serpentine, and epidote, and :wikt:platy, platy minerals such as muscovite and platy serpentine. The platiness gives the rock schistosity (a tendency to split into layers). Other common minerals include quartz, orthoclase, talc, carbonate minerals and amphibole (actinolite). Greenschist is a general field petrology, petrologic term for metamorphic rocks, metamorphic or altered mafic volcanic rock. In Europe, the term ''prasinite'' is sometimes used. A ''greenstone'' is sometimes a greenschist but can also be rock types without any schistosity, especially metabasalt (spilite). However, basalts may remain quite black if primary pyroxene does not revert to chlorite or actinolite. To qualify for the name, ...

Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 143.1 to 66 mya (unit), million years ago (Mya). It is the third and final period of the Mesozoic Era (geology), Era, as well as the longest. At around 77.1 million years, it is the ninth and longest geological period of the entire Phanerozoic. The name is derived from the Latin , 'chalk', which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation . The Cretaceous was a period with a relatively warm climate, resulting in high Sea level#Local and eustatic, eustatic sea levels that created numerous shallow Inland sea (geology), inland seas. These oceans and seas were populated with now-extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was largely ice-free, although there is some evidence of brief periods of glaciation during the cooler first half, and forests extended to the poles. Many of the dominant taxonomic gr ...

Central Mountain Range
The Central Mountain Range is the principal mountain range on the island of Taiwan. It runs from the north of the island to the south. It acts as a barrier between the east and west coasts, hindering travel. The tallest peak of the range is Xiuguluan Mountain, . Names "Central Range" or "Central Mountain Range" is a calque of the range's Chinese name, the ''Zhōngyāng Shānmài'' or ''Shānmò''. It is also sometimes simply called the Zhongyang or in English. During the Qing Dynasty, the range was known as the , from the Wade-Giles romanization of the Chinese name ''Dàshān'', meaning "Big Mountains". Geography In a broad sense, Central Mountain Range includes its conjoint ranges such as Xueshan Range and Yushan Range; thus the tallest peak of Central Mountain Range in this sense is Yushan (Jade Mountain/Mount Morrison), , and the second tallest peak is Xueshan (Snow Mountain), . Ecology The Central Range lies within the Taiwan subtropical evergreen forests ecore ... [...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] |
