First, by way of Hetian jade output points, divided into mountain since ancient times on the two production and aquaculture. Of fish known as jade, middle-of-call Baogai. Cai Yu, in accordance with local and Hetian jade output of different circumstances, be divided into Shan Liu, mountain water, sub-three.
Liu Yu-shan and famous, or Yu-Bao Gai told that produced in the mountains of the original ore. Hill is expected the characteristics of large and small block, with angular-shaped, often better-quality jade.
Mountain water is the primary ore caving weathering by water transport to the upper reaches of the river in jade. Its characteristics are the primary ore from the past, block of larger angular slightly Moyuan, a smooth surface.
---Also known as Kodama, refers to the original mine removal to erosion by flowing water in the river jade. Its characteristics are blocks of small, often oval, smooth surface. Because of long-term handling, erosion, separation, so-general of better quality. Classified by different colors
Second, and Hetian jade color can be different: white jade, Qingyu, Moyu, topaz four categories.
White jade color from white to Qingbaikou, diverse; can be divided into green and white jade Bai Yang Zhi. Yang Zhi Bai Yang Zhi for-like, Gu Ming. Delicate texture, "such as the cut-off white fat", in particular Zi Yun Guangrun, a gang of people to see Sophie's feeling, which is white jade son-in the best varieties, the world's only Hotan of Xinjiang have this variety, output is Scarce and extremely expensive. Green white jade in white as the keynote, in white jade green flash in the Yin Yin, flashing blue, gray flash, a white jade green and white jade transitional species, and Hetian jade in the more common.
Topaz from light yellow to Shenhuang Se, characterized from the inside, are yellow, Li Huang, okra yellow, yellow flower, yellow eggs, tiger, such as yellow color, topaz very rare, ancient "Huang Mou steamed pears" for those The best.
Qingyu by Dan Qingse to deep green, the color of many types, abundant reserves, is the history of jade collection or exploitation of the main varieties, the more common.
Mose Moyu from black to light, Mose mostly Yun Wuzhuang, banded, more common in Qingyu, white jade transition; generally have full-Mexican, Mexican-and Mexican points of the points, that is, the entire Mexican "black-lacquer such as" persons Shangpin is very rare. Moyu Most of the smaller pieces, with its black because of its more subtle graphite (carbon) by the scales.
And Tian Meiyu, the first theory, "Yang Zhi." And Tian Meiyu produced in so-called "million-Tsu" in the Kunlun Mountains, known in ancient and modern. Qin Li Si in his "advice Zhu Keling" listed in the four treasures Xi Shi, one of which is of Hetian jade. History last week's ceremony, Qin Yu Yuxi, Chinese jade clothing, the Tang-Lotus, the Song Yu Guanyin, the yuan Alexander Du Yuhai, the other sub-sub-Kong, and other famous jade carving of the raw materials are used and Hetian jade. Existing Leshou Tang of the National Palace Museum in Beijing, "Dayu flood control plans" is also used in Hetian jade, weighing 5,330 kilograms, for the history of our country's largest jade pieces, and the Emperor Qianlong personally Tishi. Ming Li Shizhen said: "middle-of Yiduo just independence to peace in Hetian jade." "Heavenly Creations of", he said: "All those precious jade…… do for Tian." Hetian jade in China and the great The ground leaving a brilliant chapter.
Hotan jade into Tsai Yu-shan and Liu. Yu said the river fishing, "Tsai Yu", high-quality, but production is low; ore mining is called Hill expected, the history books as "to attack Shan Cai Yu", higher yield, quality is uneven. And Hetian jade in particular, mainly middle-earners in the Yulong Kashgar River and Kalakashi River. The two River Shicheng Bai River, Moyu River, is the main origin of Hetian jade. "Xintang Shu" Description: "Yuhe, people moonlight night vision Sheng, Guo Bible." Hetian jade color can be divided into white jade, jasper, Qingyu, Moyu, topaz, blue and white, Hongyu, and so on. One of the most precious white jade is Yang Zhi-yu, condensate such as white fat. The present value of 1 kg Yang Zhi-up to more than 100,000 yuan. If a white jade in the amber of miscellaneous Banhen, higher value. Hill is expected through the jade-mining, mainly middle-county lies in the Kunlun Mountains in the region. And Hetian jade mines are located 5,000 meters above sea level in the Kunlun Mountains snow line, the exploitation period of one year only about four months. Mainly Qingyu and white jade, the finest white jade is not comparable to Tsai-yu.
And Hetian jade world-renown, Hotan jade carving is also world-renown. A unique and Hetian jade, hard texture and delicate, particularly the United States gives to the feelings, have been used for thousands of years of history, renowned at home and abroad. After Hetian jade carvings, pondering, can be made from all kinds of decorations and crafts. The late Tang dynasty Hotan jade carving industry has been. By Boyan of the Yuan Dynasty had to Hotan, in a white jade Buddha, the third year Sichi, such as color Yang Zhi, according to see all the bones and tendons Moge, a tribute that is at the top.
Soft - Second, the soft-geological characteristics of output Tarim Basin in the southern edge of the Kunlun Mountains - Aerjinshan area, from Yecheng to Qiemo, from West to Neusoft-veins Yanmian distribution of a point off more than 1,000 km, of which the Hotan River and Kalakashi, the Yulong Kashgar River nephrite The most famous and "Hetian jade" name widely circulated.
Soft jade produced in the direction of the North West - things - North East arc in the direction of the Kunlun Mountains in the groove fold uplift, the Department of acid rock, rock vein diorite intrusive rocks, quartz diorite, granite and diorite - Ma-like granite, syenite, and the Precambrian metamorphic rock of the dolomite marble, marble dolomitic calcite have contact metamorphism the product of a contact metamorphic rock category.
Dolomite marble, dolomite calcite marble in contact with the process of eradicating corruption, contact metamorphic belt, followed by a pillar of spinel stubborn fire pyroxenite, through pyroxenite, forsterite dolomite marble, dolomite tremolite Marble and soft jade, with the latter part of a soft jade - low-temperature hydrothermal alteration, such as serpentine, water magnesium petrochemical, chlorite, Waterloo petrochemical, silicified, calcite and altered.
