By their processing into the plate, crack less,[link widoczny dla zalogowanych], high rate of mineral out of wood. According to the technical evaluation, high-Chong - Shiwo tensile strength corrosion-resistant white marble, pure color, labor strength is 130 kg per square centimeter, the compressive strength over 200 kg, exceeding the worldwide standard polishing (95 degrees) to 102 degrees. High Zhuang - Shiwo white marble bomb, mining has a long history, from the Yuan and Ming has been six alternatively 7 years, the present reserve is escaping out. But the bomb to Kyoto, has made colossal contribution to the building.
Such as the Palace Museum and Hall of Preserving the lowest class piece of floor approximate the Yunlong Stone, long 16.45 meters broad and 3.06 meters, 1.7 meters thick, measuring approximately 200 tons, that namely, complete with a engraved Ai Ye; Ming Tombs Shinto two side of the stone figures, is a large stone, but too with Shiwo - tall countryside carved white relentless; outstanding Yunju Si stone along stone by the mountain embark, a absolute of 14,277 are from here; Beijing in 1958 to create " Top Ten Construction "to meet the Great Hall of the People's Heroes Monument, Revolutionary History Museum of substances, to build a nation where mining, the exploitation capability of 1,000 million cubic meters.The metropolis has more than a ten-year at the origin of marble, such as the rule of Miyun County, Silver Ridge, Bai Jian, the sometime ten shidu Fangshan, Changping County, Cliff Village - Hong Tong space, the colors are quite agreeable marble storeroom origin.
Taihu Lake stone shrieked for in the ancient garden rockery Stones, many taken from Taihu Lake because the initial underwater, hence the appoint. This rock immersed in water, but the limestone, the long wag impact and erosion, are carved into the stones embedded space. It generally has the exquisite scene, slender bone precipitous, vortex tunnel through the hole and so above,[link widoczny dla zalogowanych], some human have accustomed "thin, perspicuous, drain, furrow," the word to describe it: the so-called thin, thin shape that rocks, the air was a tendency Yuli ; the so-called permeability, texture refers to stone through to triumph over the ruffle; the so-called leakage, that there is a large stone hole hole, vulnerability phase sets, up and down throughout, circled by exquisite; the so-called wrinkled, convex and concave surface of the stone refers to the fold. Tang Wu Rong in "Taihu Song" was logged circumstance of its generation and collection: "Dongting Mountain Lake Bobi, calm stone wave eternal students. Chihiro wire way, the grotesque who can know it." Fan Chengda In the "Lake SHI Zhi," also wrote: "eroded limestone, stone raw water are good.
annuals antique urge waves, into a stone embedded space ... ...." Taihu apparent character in the formation of shock waves in counting, there are water corrosion. Taihu surface lubrication, showing the chemical dissolution of the water, while between the two erosion surfaces, brims and turns also retained the residual,[link widoczny dla zalogowanych], and some bending of the dent, it is flowing slowly forward the dissolution of the rock fractures into. Stone in the hole is the shock of mechanical abrasion and chemical dissolution of the joint forces of two "offensive" by the formation. Northern China has produced such ornamental. Such as Beijing Fangshan District, wealthy in Taihu to be known as the "Northern eroded limestone." Recently, the geology divisions of the Fangshan discovered a buried type Taihu, an area of ??several square kilometers. With the future evolution of tourism, which eroded limestone landscape in the modern usage ambition mushroom significantly. Taihu stone as a scenery of journal life will transform indispensable to enjoy the landscape. Indeed, many gardens, pavilions, activity in the Stone family preparations, numerous are eroded limestone style.
Fossils are preserved in the strata of geological period of the biological body, the remains of the remains and relics of its activities. Their conservation, and tin be divided into unchanged body fossils, alteration body fossils, molded fossils, trace fossils, fossil and additional types of chemicals. These fossils no only indicative of archaic biological survival and development of the scientific amount of the surroundings, while watching distinct voyage functionality, is a precious landscape stone. In Beijing to be rich in fossil resources.① micro-fossils of antique plants and algae. The fossils found in Beijing Ming Tombs area, the Upper Proterozoic strata. The earliest learn of the formation began in 1869, F · V · Richthofen and other areas in the south of the investigation. To 1922 A · W · Geli Pu in the south of limestone mining in the premier laminated to the ColleniaCylindrica and Csinensis fossils. Field geologist in 1923 and further study of its ditch clearance segment in the south of the ancient plant fossils and micro-algae fossils.
And later through a lot of investigation, respectively, the Upper Proterozoic Wumishan and Yangzhuang Formation embodying asphaltenes found laminated dolomite and algal density corrugated columnar algal laminated dolomite, which have to leave bare bough stromatolites - Cup stromatolites - cone represented by stromatolites thick algal reef system and chiefly spherical, ellipsoid and filamentous algae, single cell microbial mats composed of fossils. Various shapes of these fossils are the remains of ancient algae play. In addition, holes in the Longmen Jian Zhang public dolomitic limestone near the thick layer of smooth surface, also found a large digit of laminated algae fossils, they are not only a explicit framework, and quite smart. If you mow the stone, then longitudinal sections showing a cylinder fashion, across section and show a normal pattern of concentric surrounds. According to the research, which is grown in the past 10 billion years antecedent, groups of biological remains in superficial water.
