Yandang Mountains
Yandang Mountains or Yandangshan () refers, in the broad sense, to a coastal mountain range in southeastern Zhejiang province in eastern China, covering much of the prefecture-level city of Wenzhou (from Pingyang County in the south to Yueqing County in the northeast) and extending to the county-level city of Wenling in Taizhou prefecture. The mountain range is divided in two by the Oujiang River, the two parts being the North Yandang and South Yandang. More narrowly, Yandangshan is also used to refer to , a specific part of the North Yandang around an ancient caldera near a small town of the same name (). The highest peaks of North Yandang are located here, and this is also the main tourist spot. In this article, name "Yandang Mountains" is used to refer the mountain range and "Mt. Yandang" to refer to the caldera. The main peak of North Yandang, Baigangjian (), rises above sea level [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Intrusion
In geology, an igneous intrusion (or intrusive body or simply intrusion) is a body of intrusive igneous rock that forms by crystallization of magma slowly cooling below the surface of the Earth. Intrusions have a wide variety of forms and compositions, illustrated by examples like the Palisades Sill of New York and New Jersey; the Henry Mountains of Utah; the Bushveld Igneous Complex of South Africa; Shiprock in New Mexico; the Ardnamurchan intrusion in Scotland; and the Sierra Nevada Batholith of California. Because the solid country rock into which magma intrudes is an excellent insulator, cooling of the magma is extremely slow, and intrusive igneous rock is coarse-grained ( phaneritic). Intrusive igneous rocks are classified separately from extrusive igneous rocks, generally on the basis of their mineral content. The relative amounts of quartz, alkali feldspar, plagioclase, and feldspathoid is particularly important in classifying intrusive igneous rocks. Intrusio ...

Cabot's Tragopan
Cabot's tragopan (''Tragopan caboti'') is a pheasant found in south-east China. The common and scientific names of this large bird both commemorate the ornithologist Samuel Cabot III. Other common names include the Chinese tragopan and the yellow-bellied tragopan. The population is divided into two subspecies, of which the dominant subspecies is found in the provinces of Fujian, Jiangxi, Zhejiang, and Guangdong, and ''T. c. guangxiensis'' is confined to northeastern Guangxi and southern Hunan. The IUCN has assessed it as being a "vulnerable species". Description Cabot's tragopan is a plump ground-dwelling bird with relatively short legs. The male grows to a length of about and a weight of around while the female is about shorter and weighs around . The head of the male is black with reddish-orange streaks on either side and on the neck and similar-coloured bare skin on the cheeks and around the eye. Below the beak dangle blue and orange decorative, inflatable wattles and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arachniodes
''Arachniodes'' is a fern genus in the family Dryopteridaceae (wood ferns), subfamily Dryopteridoideae, in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). A number of species in this genus are known as "holly ferns". The genus ''Arachniodes'' was first published by Carl Ludwig von Blume in 1828, with the single Indonesian species ''Arachniodes aspidioides''. The genus was not widely recognized until Mary Douglas Tindale transferred the two species (''Byrsopteris amabilis'' and ''Byrsopteris aristata'') into it in 1961.Tindale, Mary Douglas; ''Contributions from the New South Wales National Herbarium'' 3(1): 90. 1961.

Carex
''Carex'' is a vast genus of over 2,000 species of grass-like plants in the family (biology), family Cyperaceae, commonly known as sedges (or seg, in older books). Other members of the family Cyperaceae are also called sedges, however those of genus ''Carex'' may be called true sedges, and it is the most species-rich genus in the family. The study of ''Carex'' is known as caricology. Description All species of ''Carex'' are perennial plant, perennial, although some species, such as ''Carex bebbii, C. bebbii'' and ''Carex viridula, C. viridula'' can fruit in their first year of growth, and may not survive longer. They typically have rhizomes, stolons or short rootstocks, but some species grow in tufts (caespitose). The culm (botany), culm – the flower-bearing stalk – is unbranched and usually erect. It is usually distinctly triangular in section. The leaf, leaves of ''Carex'' comprise a blade, which extends away from the stalk, and a sheath, which encloses part of th ...

Pine
A pine is any conifer tree or shrub in the genus ''Pinus'' () of the family Pinaceae. ''Pinus'' is the sole genus in the subfamily Pinoideae. ''World Flora Online'' accepts 134 species-rank taxa (119 species and 15 nothospecies) of pines as current, with additional synonyms, and ''Plants of the World Online'' 126 species-rank taxa (113 species and 13 nothospecies), making it the largest genus among the conifers. The highest species diversity of pines is found in Mexico. Pines are widely species distribution, distributed in the Northern Hemisphere; they occupy large areas of boreal forest, but are found in many habitats, including the Mediterranean Basin, and dry tropical forests in southeast Asia and Central America. Wood from pine trees is one of the most extensively used types of timber, and some pines are widely used as Christmas trees. Description Pine trees are evergreen, coniferous resinous trees (or, rarely, shrubs) growing tall, with the majority of species reachin ...

Cunninghamia
''Cunninghamia'' is a genus of one or two living species of evergreen coniferous trees in the cypress family Cupressaceae. They are native to China, northern Vietnam and Laos, and perhaps also Cambodia. They may reach in height. In vernacular use, it is most often known as ''Cunninghamia'', but is also sometimes called "China-fir" (though it is not a fir). The genus name ''Cunninghamia'' honours Dr. James Cunningham, a British doctor who introduced this species into cultivation in 1702 and botanist Allan Cunningham. A female cone Cluster of male cones Description The general shape of the tree is conical with tiered, horizontal branches that are often somewhat pendulous toward the tips. ''Cunninghamia'' bears softly spined, leathery, stiff, green to blue-green needle-like leaves that spiral around the stem with an upward arch; they are 2–7cm long and 3–5mm broad at the base, and bear two white or greenish white stomatal bands underneath and sometimes also above.

Tuff
Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. Following ejection and deposition, the ash is lithified into a solid rock. Rock that contains greater than 75% ash is considered tuff, while rock containing 25% to 75% ash is described as ''tuffaceous'' (for example, ''tuffaceous sandstone''). A pyroclastic rock containing 25–75% volcanic bombs or volcanic blocks is called tuff breccia. Tuff composed of sandy volcanic material can be referred to as volcanic sandstone. Tuff is a relatively soft rock, so it has been used for construction since ancient times. Because it is common in Italy, the Romans used it often for construction. The Rapa Nui people used it to make most of the ''moai'' statues on Easter Island. Tuff can be classified as either igneous or sedimentary rock. It is usually studied in the context of igneous petrology, although it is sometimes described using sedimentological terms. Tuff is often erroneously called t ...

Syenite
Syenite is a coarse-grained intrusive igneous rock with a general composition similar to that of granite, but deficient in quartz, which, if present at all, occurs in relatively small concentrations (< 5%). It is considered a granitoid. Some syenites contain larger proportions of components and smaller amounts of material than most granites; those are classed as being of . The |
