Natural Chinese cinnabar origin

What is cinnabar, cinnabar, formerly known as cinnabar, was named after the earliest discovery in Chenzhou (now Fuling) in Hunan; it is the main raw material for mercury refining, also known as mercury sand; and because it is red, commonly known as dansha, danjiang, red Dan, cinnabar.

The world's cinnabar is mainly distributed in China, the United States, Spain, Mexico, Russia, Yugoslavia and other countries.

The distribution of natural Chinese cinnabar origin is compared in several provinces.

In China, in addition to Hunan Fuling production, Sichuan, Hubei, Shaanxi, Qinghai, Gansu, Yunnan, Guangxi, Guizhou provinces, the proven cinnabar stone production area of ​​50, the reserves of more than 200,000 tons. There are as many as 50 proven cinnabars in Guizhou Province, and the cinnabar production in the eastern part of Guizhou and Hunan is 80% of the country.

Wang Wenzheng, a famous modern stone theorist, said in the book "Chinese Stone Play Stones": "The place where cinnabar is produced in China is the most expensive in Guizhou Province, and it is spread all over the province. The Wanshan Dolomite Cave is the cinnabar gemstone. The world's “Wanshan Special Zone” is rich in mercury and cinnabar. It is the largest production base of mercury and cinnabar in China and enjoys the reputation of “China's mercury capital”.

The characteristics and special effects of cinnabar

The ancient book "Suyuan Stone Spectra" is called Chenzhou sand bed, and has a concise and vivid description of its origin, collection, shape and color: "Chenzhou sand red, producing 冉家岩洞. There are sand pits, deep fifteen The six people are faint and black. The natives use the leather cap to hang the light and dig it into the rock. The white stone is like a sand bed, the big one is like a chicken, the small one is like a garnet. For example, if the diners are bed-ridden, if the sable is iron-colored and bright, it can be placed in several cases.” The chemical composition of cinnabar is mercury sulfide; the trigonal system, the crystal is plate-shaped or rhombohedral, The body is granular, massive or earthy. The crystal clusters are often rhomboid double crystal, large particle single crystal, translucent or opaque, bright red, vermilion, light red, dark red or streak red, brittle, sensitive to light, very The high refractive index, the bloodstone is formed by sand and sand condensed in the rock fissure. Metallic luster, diamond luster or glass luster, Mohs hardness of 2.5, specific gravity of 8.2.

Zhusha jade uses Chinese medicine to calm down, calm the nerves, attending madness, sweet, slightly cold, and poisonous by fire. It is only produced in volcanic rocks, hot spring sediments, low-temperature hydrothermal deposits, fault breccia dolomite crystal caves, and often symbiotic with quartz, realgar, orpiment, calcite, stibnite, pyrite, and chalk.
