mainly in Xinjiang and Tian Kunlun Mountains area. Taxkorgan west, east Qiemo, up to 1,300 km in the foothills of the Kunlun Mountains and the rivers in the riverbed, has been found and nephrite deposits and ore than 20 points, constitute an extremely important in China and Tian metallogenic belt. White is jade in a variety of treasures, because of its pure and gentle, delicate and beautiful, absolutely fine Lun many white objects, people put it down. Representative of the excellent quality white gentleman's virtue, how the subject of worship for thousands of years will be marked as a treasure. And Tian Baiyu white suet is the best.
two suet white Hotan jade quality, hardness and toughness
(a) of the white jade
suet's name because it resembles from a sheep with Creamy body fat extracted from the kind of white-run level of gloss. This gloss is not a dazzling reflective glass and metal, and not the other kind of damp oily, greasy feel of light, not strong, not weak but a moderate-intensity soft luster is very calm, sparkling, and not harsh, giving a very cute small white moist feeling.
suet jade white jade, which are summarized as .
1, suet white of the To understand the degree of moisture white suet, as long as it should be through the stroke to experience that feeling. Suet Ying white or hand grip to graze, not too long, palm spring moisture will produce a micro sense, but not the kind of hit first, and then hand sweat wet sense of the kind of jade, but because the kind of heat stroke emerged feeling slightly moist. Intrinsic naked, soft run the United States, easily satisfied the weather, micro-spring breeding, giving visually attractive, tactile comfort, this is the suet white moisture characteristics.
2, suet white of the White was originally a cold tone, coupled with their own characteristics jade, Yu-yi first touch when there is a sense of cool, because the density of suet and oily white, red and cool colors to this, looking not very a strong sense of thermal or cold. So suet white always seems to give a very gentle, very gentle, but also with a little tenderness, very cute.
3, suet white's Any objects are light to reflect through his shape and color. Gloss white suet mainly in oils and fats like oil sheen, is an oil but not greasy, sparkling and soft sheen. Very pure whiteness of color, even.
4,UGG bailey button, suet white Of suet white That is, pure white, no impurity, there is no flaw in the jade sheltered spot, very clean and white, as white as tallow. However, what kind of suet white? Closer look will find: first, a white suet whitens, the kind of rich creamy soft white gloss, not the kind of dry pale dry; Second, suet is a warm white white white , a mild sense of white people, is a not cold not hot, neutral tones. From the chromatographic point of view, the tone on the white with a slightly pink hue is overheated; slightly with the sky blue, it is the cold side of the color. The warm colors are white with a very slightly lighter in color yellow, like 99% white and 1% of the organic integration of pale yellow with a very evenly, and slightly translucent, transparent material instead of the degree of visibility. This is a rich spirit of the warm and clean whiteness. This is also the daily lives of white people to pursue the kind of penetration with a girl as dainty white, giving a pressure depression is not very comfortable white.
5, suet white of the High hardness of white suet, about 6.5 to 6.9 degrees. Toughness is also very strong. Suet white on the hands, gently caress would be very fine lubrication. This white suet lubrication, light hand touch is Yu-yi, to feel the slippery touch white suet, and is not a greasy slippery. Looks soft, with the palm of your hand hold up, they get the same size than the other jade weight, there is a ChenDian sense, jargon, the This is because the crystal structure of suet very fine white solid result. The white suet density, high hardness, toughness, not easy to be in the air or water in the various chemical and physical factors, disseminated corrosion, durable resistance to save, not easy to Bianse deterioration. We observe, or handed down to those unearthed in the ancient pieces of white suet suet will feel superior to the close nature of white, even white suet pieces of ancient Qin surface of a small number of colors, almost impossible to in-depth internal Yu-yi. Suet jade unearthed device finish (polished surface) almost unearthed as new, white Tsai Yu-suet, or tens of thousands of years, the impact of years in the water in the collision, the friction on the skin may precipitate signs of cleaning with some of the water condensate minerals, due to the formation of jade colored skin, which is firmly attached to Yu Yu-yi skin surface, but not intrusive Yu-yi inside. This is due to a high degree of close nature of white suet reason.
6, suet white of the Were good suet translucent white, jade uniform, no impurities, giving a sense of intrinsic Baoguang. Suet as it caress long white plate, within the Yu-yi will also be gradually out thoroughly, and nothing left to leak out, both inside and outside of pure profit, this time Aura show, this is the place to the United States white suet.
the suet fine dense white, with light there is always a feeling like through non-transparent, transparent suet white, whiteness also will be under the lung, but the suet white no matter how not all through. Through it all the jade was not called suet.
Run with the necessary degree, moderate degree, Ying Ze degree, through the fineness, whiteness, and muddy as one who is white suet.
(b) the hardness and toughness of white suet
by the determination of Hotan jade suet hardness of 6.5 to 6.9, hardness is relatively large, so polished jade is good, but long-term Save. Suet Hotan jade and nephrite as with other genera tremolite, big is its characteristic toughness. According to the toughness of the world's gem materials, Black Diamond is 10, tremolite 9, emerald, ruby, sapphire 8, diamond, crystal,UGG shoes, aquamarine is 7 to 7.5, olivine is 6, emerald 5.5, topaz, moonstones 5, 3 opal, fluorite 2. If the tremolite toughness of 1000, other relative toughness of jade or mineral: 500 jade, serpentine (as Jade) 250, 10 to 20 quartz, quartz, 5, 2 to 3 corundum, mica 2. Visible, tremolite jade is the largest in the toughness, the toughness is large, easily broken, and wear, for the art form and carved jade of great benefit, which is white as a group of Hotan jade suet important factor in the British.
Third, Hotan jade geological setting and mineralization suet conditions
(a) of the geological background
Xinjiang and Tianbai Yu (tremolite) mainly in the Kunlun Mountains . Kunlun Mountains and Tian, also called Kunlun Jade, also known as Kunshan jade. Hotan Prefecture as one of tremolite produced by the most famous, will be their habits, said, And nephrite jade dominated by,UGG boots cheap, but also green and white marble, the famous The Kunlun Mountains and nephrite (tremolite) origin can be divided into Yarkand - Yecheng area, Hotan - Yutian region and Qiemo - Ruoqiang region. Yarkand - Yecheng approximate location of areas in the East Trail 76 ° ~ 78 ° between the known origin have Taxkorgan County Library Datong jade mine and Yecheng waves that jade ore, mainly produced and nephrite jade, plays for the Green white, white is less common occurrences have close Erdai Hill and Martha Hooper Hill. Mountainous region, transport extreme new plugs, but the massive Qing Dynasty jade material produced frequently. Song Qing Dynasty in the jade material. Beijing Palace Museum Treasures from the Museum of jin Hotan - Yutian area is located in east longitude 78 ° ~ 82 ° between the major deposits and occurrences are: Kara Pishan County board and iron large white Mi, Hotan County, home to change and Ao Misha Agger, on field County, Ala Masi. The most famous change in the Arab home Masi Agger mine (the Qianlong reign began mining in 1995 has not mine out, so this is also known as Ninth mineral jade material, to produce the famous white world, in recent Yushan Bai materials produced for centuries the main mines. Ala Masi ore than white, there are jade green, jade, the jade ore quality is very good). Jade plants produced in this area are complete, in addition to white and green jade, there are jade, black jade and topaz.

Original deposit or mine the area points are produced in the late Proterozoic Jixian System or the Department of the Great Wall and dolomitic marble in the acidic late Variscan intrusive contact zone. Qiemo - Ruoqiang Hotan area bed and mine too mine has three points, namely, Qiemo mine, hada black tournament Qitai for ore mining and Denktash, 3500 ~ 4500m above sea mining in the mountain areas , to jade jade plants produced the most, there is sapphire.
and nephrite by cause and occurrence of ore can be divided into primary and secondary ore. Mine has the original famous jade, is produced in the primary deposits of jade. Recovery after irregular rules for the massive, angular obvious. Aberdeen secondary jade mine in Xinjiang, said materials or Aberdeen, the primary tremolite, deposit by the internalization of erosion, erosion, transportation to the river, in the appropriate place or deposit into the secondary mineral deposits. Jade degree of different sizes, good roundness, often has ellipsoid, flat ball and so on. Mainly in Aberdeen and Tian Yulong Kashgar River and Kalakashi River bed, the bed is taken from two to account for all of Aberdeen, Aberdeen, Yu Yu yield 95%.
