The press conference of the 5th China (Hunan) International Mineral and Gem Expo was held in Chenzhou.
The reporter learned from the press conference of the 5th China (Hunan) International Mineral Gem Expo that a new kind of jade resource was discovered in Xianghualing, Linwu County, Chenzhou City in May 201June. It was identified as tremolite jade with very similar characteristics to Hetian jade and named as "Xianghuayu". This is another major discovery in Hunan after Tian Tongyu.
Xianghuayu is calm and rich in color, delicate and moist in texture, mostly native mountain material, with large volume, good quality and few cracks. Mainly cyan and dark green, with solemn tone and strong toughness. It is a high-grade and high-quality raw material for processing and making jade articles.
Through analysis and test, Hunan Institute of Geological Testing shows that the main minerals that make up Xianghuayu are tremolite and actinolite, which are interwoven into fibers, very similar to Hetian jade. According to the determination of Hunan Academy of Geological Sciences, Xianghuayu is produced in contact metasomatic jade deposits and is rich in calcium, magnesium, iron and other elements. The mineralization bandwidth is 0.5 to 2.5 meters, and the average width is about 1.5 meters.
Wang Liyao, director of the Geological Exploration Department of Hunan Provincial Department of Land and Resources, said that in recent years, the Hunan Provincial Party Committee and the provincial government have made great efforts to build the gem and jade industry into a green industry that "adjusts the structure and promotes development". Among them, Tian Tongyu and Xianghuayu in Linwu are precious jade resources, which are listed as the key development projects of high-value ore industry in Hunan Province and the first of the top ten emerging industries development plans in Chenzhou City. Linwu will carry out protective development of gemstone resources, plan and build a gemstone cultural industrial park, and build a well-known gemstone distribution center in China.
Hunan Tian Tongyu introduced:
Tian Tongyu is a long-standing jade culture product of the Chinese nation, named after it was produced in Tongtianling, Linwu County. Linwu County is the only jade-producing county in Hunan Province so far. The jade resources contained in the territory are widely distributed, with various types, rich colors, high hardness and strong carving, and Tian Tongyu is the most representative.
Common Tian Tongyu is white, yellow, red, brown, gray and blue. Jade is delicate, natural and bright, crystal clear. According to the preliminary exploration calculation of Hunan Nonferrous Geological Exploration and Research Institute, Tiantong jade has a reserve of more than 8 million tons, which has great development potential. 20 15 12 the local standard of tongtianyu Hunan province was officially implemented, which filled the blank of the standard of no jade in Hunan and rewritten the history of no jade in Hunan.
