Gongshi
''Gongshi'' (), also known as scholar's rocks, are naturally occurring or shaped rocks which are traditionally appreciated by Chinese scholars.Metropolitan Museum of Art "The World of Scholars' Rocks Gardens, Studios, and Paintings" retrieved 2012-12-20. The term is related to the Korean ''suseok'' () and the Japanese ''suiseki'' (). Scholars' rocks can be any color, and contrasting colors are not uncommon. The size of the stone can also be quite varied: scholars' rocks can weigh hundreds of pounds or less than one pound. The term also identifies stones which are placed in traditional Chinese gardens. History In the Tang dynasty, a set of four important qualities for the rocks were recognized. They are: thinness (瘦 shòu), openness (透 tòu), perforations (漏 lòu), and wrinkling (皺 zhòu). Gongshi influenced the development of Korean ''suseok'' and Japanese ''suiseki''. Sources There are three main Chinese sources for these stones. * Lingbi stone (''Lingbishi'') (Chi ...

Suiseki
In traditional Japanese culture, are small naturally occurring or shaped rocks which are appreciated for their aesthetic or decorative value. They are similar to Chinese scholar's rocks.Cousins, Craig. (2006) ''Bonsai Master Class,'' p. 244 History Chinese scholar's rocks called ''gongshi'' influenced the development of ''suiseki'' in Japan. The history of ''suiseki'' in Japan begins during the reign of Empress Suiko. The small objects were brought to Japan as gifts from the Chinese Imperial court. ''Suiseki'' are usually presented in two different ways: *The stone is provided with a wooden base (''daiza''). *The stone is placed in a waterproof tray or bowl of ceramic (''suiban'') or bronze (''doban''). These stones are not just any stones which can be found in nature; they must be expressive stones and have a special shape, color and texture to be categorized as ''suiseki''. There is a distinction between landscape and object stones. The former reflect landscapes such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South China Karst
The South China Karst (), a UNESCO World Heritage Site since June 2007, spans the provinces of Chongqing, Guangxi, Guizhou, and Yunnan. It is noted for its karst features and landscapes as well as rich biodiversity. The site comprises seven clusters Phase I: Libo Karst, Shilin Karst, and Wulong Karst inscribed in 2007, and Phase II: Guilin Karst, Shibing Karst, Jinfoshan Karst, and Huanjiang Karst inscribed in 2014. UNESCO describes the South China Karst as "unrivalled in terms of the diversity of its karst features and landscapes."

Speleogenesis
Speleogenesis is the origin and development of caves, the primary process that determines essential features of the hydrogeology of karst topography, karst and guides its evolution. It often deals with the development of caves through limestone, caused by the presence of water with carbon dioxide dissolved within it, producing carbonic acid which permits the dissociation (chemistry), dissociation of the calcium carbonate in the limestone. Limestone The majority of limestone caves are created by calcium carbonate Dissolution (chemistry), dissolution by the solvent action of meteoric waters circulating through the rock. In the presence of carbon dioxide saturated water, calcium carbonate reacts to form the soluble calcium bicarbonate. CaCO3 + CO2 + H2O → Ca(HCO3)2 As meteoric waters precipitate they dissolve atmospheric carbon dioxide to form a dilute carbonic acid solution, which builds up in permeable Fracture (geology), fissures, Bed (geology), bedding planes, joints, and Fau ...

Bedrock
In geology, bedrock is solid Rock (geology), rock that lies under loose material (regolith) within the crust (geology), crust of Earth or another terrestrial planet. Definition Bedrock is the solid rock that underlies looser surface material. An exposed portion of bedrock is often called an outcrop. The various kinds of broken and weathered rock material, such as soil and subsoil, that may overlie the bedrock are known as regolith. Engineering geology The surface of the bedrock beneath the soil cover (regolith) is also known as ''rockhead'' in engineering geology, and its identification by digging, drilling or geophysics, geophysical methods is an important task in most civil engineering projects. Superficial deposition (geology), deposits can be very thick, such that the bedrock lies hundreds of meters below the surface. Weathering of bedrock Exposed bedrock experiences weathering, which may be physical or chemical, and which alters the structure of the rock to leave ...

Karst Topography
Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German in the late 19th century, which entered German much earlier. ...

Guilin
Guilin ( Standard Zhuang: ''Gveilinz''; alternatively romanized as Kweilin) is a prefecture-level city in the northeast of China's Guangxi Zhuang Autonomous Region. It is situated on the west bank of the Li River and borders Hunan to the north. Its name means "forest of sweet osmanthus", owing to the large number of fragrant sweet osmanthus trees located in the region. The city has long been renowned for its scenery of karst topography. Guilin is one of China's most popular tourist destinations, and the epithet "By water, by mountains, most lovely, Guilin" () is often associated with the city. The State Council of China has designated Guilin a National Famous Historical and Cultural City, doing so in the first edition of the list. History Before the Qin dynasty, Guilin region was settled by the Baiyue people. In 314 BC, a small settlement was established along the banks of the Li River. During the Qin dynasty's (221–206 BC) campaigns against the state of Nanyue, the fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gong Shi
Gong Shi () was a policy in ancient China during the reigns of emperors Dezong () and Shunzong () of the Tang dynasty in which the emperor would send eunuchs to civilian markets to purchase goods by force at very low prices. This system was abolished by Reformists led by Wang Shuwen () under the rule of Emperor Shunzong. History Researches published by City University of Hong Kong and Fudan University show that the earliest record of Gong Shi can be traced back to 707, according to two biographic sketches of Emperor Zhongzong (). At first, the Gong Shi was merely certain kind of imperial entertainment, until the period of the Emperor Xuanzong (), when the entertainment tended to become a commercial practice adopted to serve the need of the palace. Before the ''Zhenyuan'' () period of the reign of Emperor Dezong, if the palace required supplies, then the officials responsible for procurement would settle the bill immediately after a purchase. Originally these officials wer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fractal
In mathematics, a fractal is a geometric shape containing detailed structure at arbitrarily small scales, usually having a fractal dimension strictly exceeding the topological dimension. Many fractals appear similar at various scales, as illustrated in successive magnifications of the Mandelbrot set. This exhibition of similar patterns at increasingly smaller scales is called self-similarity, also known as expanding symmetry or unfolding symmetry; if this replication is exactly the same at every scale, as in the Menger sponge, the shape is called affine self-similar. Fractal geometry lies within the mathematical branch of measure theory. One way that fractals are different from finite geometric figures is how they scale. Doubling the edge lengths of a filled polygon multiplies its area by four, which is two (the ratio of the new to the old side length) raised to the power of two (the conventional dimension of the filled polygon). Likewise, if the radius of a filled sphere i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
