Nowadays, due to the lack of popularity of Hetian jade knowledge, people have very little understanding of Hetian jade, and few people can distinguish the real sheep fat jade. The following will analyze the five characteristics of the lower fat jade for the Yuyou: Pure texture The content of tremolite minerals in sheep fat jade is as high as 99%. The sheep fat jade only exists in the most perfect part of the wall rock alteration. When the granodiorite body is in contact with the dolomite, a series of contact metamorphic rocks are produced, and the dolomite becomes a dolomite marble. The late magmatic hydrothermal fluid forms a fissure channel along the dolomite marble, which is formed by the metamorphism. Stone rock. Because the surrounding rock erosion has become three kinds of lithofacies of dolomite marble-diabolomic dolomite marble and tremolite, the sheep fat jade is present in the tremolite rock facies. 2. Fine structure The tremolite in the sheep fat jade is microscopically crystallized and aggregated. The crystallite size of the tremolite can be determined under electron microscope and optical microscope. The length of the tremolite fiber in the suet jade (longitudinal) is 0.033- 0.01mm, width (transverse) 0.0006-0.001mm, these microscopic, fluffy, felt-like tremolite crystals are intertwined to form a pile-like structure, a felt-like structure, and an interwoven structure. Microscopic, fluffy, felt-like tremolite crystal aggregates, characterized by orthogonal polarized light, do not exhibit uniform extinction at the same angle. 3. Water head Water head and spirit land are the names of jade transparency. In tremolite jade, the thickness is usually 2mm. The white jade is translucent-opaque in this criterion. The head of the suet jade is translucent. 4. Color sheep fat white Sheep fat white is not pure white, but white with oily luster. Some in white can reveal a slight yellow color, and poor texture can also reveal a slight light gray tone in white. 5. Oily weight In the process of constant touch in the palm of the hand, the fat jade jade naturally produces an "oily" feeling on the surface of the jade. This phenomenon also occurs in some Hetian fine white jade. When the sheep fat jade falls in the water, the jade body is lifted. It can be dripping without sticking, so the oily heavy sheep fat is also very good, so-called cotton, which is toughness.
