Lingbi stone, belonging to the metamorphic rock of jade, is a crypto-crystalline limestone composed of fine-grained particles of calcite, which is dark or patterned with metallic minerals or organic matter. Produced in Jinyun Mountain, Lingbi County, Anhui Province, Lingbi Kistler was formed more than 800 million years ago. Lingbi stone is mainly produced in Lingbi County, Anhui Province. “Suibin Floating Temple” (commonly known as “Lingshi Stone”) and “Lingshi Stone” are two different concepts, and they are two different branches in the stone culture department of Lingbi County. "Lingshi Stone" refers to the flaky Lingbi from the Nantun ancient antimony ore in Jinyun Mountain, Lingbi County. A stone that can make a pleasant sound. A thickness of 50 cm is a rare meteorite.

Lingbi stone, a jade-like metamorphic rock, is a crypto-crystalline limestone composed of fine-grained particles of calcite. It is dark or patterned with metallic minerals or organic matter. Produced in Jinyun Mountain, Lingbi County, Anhui Province, Lingbi Kistler was formed more than 800 million years ago. Lingbi stone is a collection of quality, sound, shape and color. It plays an important role in the long-standing Chinese stone culture. It is a recognized stone treasure in the past and the present. Lingbi stone is mainly produced in Lingbi County, Anhui Province. “Suibin Floating Temple” (commonly known as “Lingshi Stone”) and “Lingshi Stone” are two different concepts, and they are two different branches in the stone culture department of Lingbi County. "Lingshi Stone" refers to the flaky Lingbi from the Nantun ancient antimony ore in Jinyun Mountain, Lingbi County. A stone that can make a pleasant sound. A thickness of 50 cm is a rare meteorite. In the "Yunlin Stones", Song Dynasty Du Fu carried 116 kinds of stone products, and Lingbi Stone ranked first. "There is a stone in the sky, and the sound is like a bronze color like jade." This is the sincere admiration of the poet Fang Yan of the Song Dynasty. The development of Lingbi stone has a history of three or four thousand years, "Shangshu·Yonggong" contains "Suibin floating raft"; in the Yin Shang period, there is a record of the palace musical instrument - the tiger stone sarcophagus; 》: The emperor ordered the general of the town of Xie Shanglai to pick up the stone to prepare for the Da Lejiang left... In addition to the meteorite, the Lingbi stone has more exotic ornamental stones, and its production area is not limited to the area of ​​the meteorite mountain. In the northern part of the county, such as Lingjue Mountain, Chaoyang Mountain, Baima Mountain, Erma Mountain, Shaoshan Mountain, Jiuding Mountain, etc., there are also a small distribution in the area of ​​the Sanyue Mountain in the middle of the county and the Dashan Mountain in the south. Judging from the already produced Lingshi, its true charm is not only the talent of its inner aura and shape, but its quality, shape, color and pattern have high artistic appreciation value. Praise it as "the first stone in the world." Ornamental stone, also known as "Kistler", "Qiao Shi", "stone play", "appreciate stone", etc., most of them are strange in shape, bright in color, beautiful in appearance, tough in texture, and have ornamental value. After being collected, trimmed or slightly processed, it can become a special natural art. The coffin ornamental stone is divided into more than one hundred varieties of black, white, red and gray. Among them, black is the most distinctive. Look at it, its color is like ink; hit it, its sound is like a slap. Its shape is similar to the name of Xianshan, or like a rare bird or a beast, or like a famous poet. It has been praised by the domestic and international stone art circles as "the world's first stone". The stone body of Lingbi Stone is melted, leaked, thin, wrinkled, sui, hanging, sui, color, and the beauty of phonology and many other aesthetic elements, not only tolerate the "four-character" of Mi Fu, but also unique to Lingshi. The beauty of the United States is beautiful, beautiful and innocent, the "first stone in the world". Geographical features In the territory of Lingbi County during the ancient Sinian period (about 8 to 4.4 billion years ago), through the Lüliang tectonic movement, the sea water flooded into the territory, making the Lingbi a shallow seashore. During this period, the original algae plants proliferated in large numbers to form reefs, which developed into various types of stone ore bodies under the action of marine sedimentation. The Sinian-Organian carbonate rocks are deposited and formed on the Sinian structure. In ancient times (about 4-230 million years ago), after the Caledonian tectonic movement, the earth's crust was raised to land. After the Hualixi tectonic movement, it sinks into a shallow sea lagoon. Until the Mesozoic (about 200 million years ago), after the Indosinian tectonic movement, the belt was raised to the land, and the sea water disappeared. At the same time, during the movement of the Indo-Chinese structure, wrinkles and fractures occurred in the territory. In the late Jurassic to Cretaceous, Yanshan tectonic movement occurred, accompanied by volcanic eruption activities, and magmatic rock geology appeared. Entering the Cenozoic (1.2 million years ago), Tertiary strata were deposited in the limestone erosion zone. Nearly 1 million years, the formation of the Quaternary impact plains. Most of the above strata are hidden under the Quaternary, and a few sporadic outcrops are exposed in the denuded hills of the low hills. After a long and complicated geographical change, a special geological and styling wall stone has been formed.

Technical requirements for quality of Lingbi stone (1) Mining and cleaning. 1. Mining: Mining must maintain the original appearance of the stone, and there must be no obvious damage. Small blocks are mined by hand from the ground; medium blocks are mined, and wood rods or steel brazing are used appropriately; large blocks can be mined with cranes, excavators and other machinery. Mining implements a mining permit system and prohibits the use of destructive mining methods such as blasting. 2. Cleaning: first remove the dirt, stone alkali, stone scale and other attachments on the surface of the stone, then soak the original stone, brush it gently with a brush or wire brush, and finally wipe the surface with paraffin. Then, according to the type of Lingshi stone, the base of different materials is used. Artificial processing such as carving, drilling, bonding or dyeing is prohibited. (2) Quality characteristics. According to the shape, texture, sound, color and texture, Lingshi Stone can be divided into Qinglan Lingshi, Lingbi Stone, Lingbi Stone, Colorful Lingshi, Bailing Stone, Lingbi Stone, Red Lingshi, etc. Seven categories. 1. Sensory features: (1) Qinglan Lingshi: The color is black and black, and the knocking sounds a crisp sound. (2) Lingbi stone: The color is black and black, and the surface has one or more irregular textures such as straight lines, arc lines, circle lines and money, butterflies, and clouds. (3) Lingbi snail: the surface is spirally shaped (like a snail shell) and the color is red, yellow and gray. (4) Multicolored Lingshi: A stone body is in a variety of colors, including yellow, enamel, red, blue, and white. (5) Bailing meteorite: the color part or most of it is pure white, and the rest is blue and gray. (6) Lingbi transparent stone: the color is black and gray, and there are figures, plants, mountains, clear streams, Chinese paintings and other patterns on the surface, which have a strong sense of ink. (7) Red Lingshi: The stone is red. 2.
