Third, resource forecasting and development advantages
Hetian jade is China's dominant mineral. The storage capacity in Xinjiang is even more amazing. The Kunlun Mountains and the Altun Mountains are the main distribution areas. More than 20 primary mines have been discovered. According to the existing situation, it is in Hetian. - There are more than 100 Hetian jade mines in the Kunlun Mountains, which are about 450km long in the Yutian area. If the average reserves of each jade mine are 500 tons, the storage capacity of Hetian jade in this area alone is about 50,000-100,000 tons.
In addition, there are five mines in the territory of Hefei County, which are about 110 kilometers long. The mineralization belt is large in scale, with many veins and ore bodies. The Hetian jade reserves are about 330,000 tons, which is almost the current county. 30 times of the total amount of mining; and if there are many ore bodies in the Ruoqiang area, the degree of work is low, and there is also great resource potential, which is another important production area of ​​Hetian jade. Therefore, the end-Jiaoyu area is also the main prospecting area for Hetian jade in the future.
Hetian jade is a dominant mineral resource in Xinjiang and has obvious advantages in industrial development:
1. Hetian jade has a long history and laid a solid foundation for the long-term development of Hetian jade industry.
China produces dozens of kinds of jade and produces more than 100 places. However, only Hetian jade and Hetian jade are known as "national jade" in China. They have been developed and utilized about 10,000 years ago. According to records, some experts have proposed that the famous "Silk Road" was developed on the road of jade formed by the transportation of Hetian jade to the Eurasian countries thousands of years ago. Hetian jade has become an important carrier for the exchange of Chinese and Western materials and cultural exchanges. Coupled with the current national strategy for the Belt and Road Initiative, it provides a good opportunity for the better continuity and development of the Silk Road, and also lays a solid foundation for Hetianyu's industrial development.
2. Hetian jade has a solid cultural foundation and provides broad prospects for the long-term development of Hetian jade industry.
Hetian jade has always occupied an important position in the Chinese national culture. The traditional Chinese Confucian culture has given Hetian jade the meaning of "benevolence, righteousness, wisdom, courage and cleanliness", which makes Hetian jade possess personality and respect jade. , Ai Yu, Pei Yu, and jade are also the ancient traditions of the Chinese nation. Up to the king will be the same, and the people of the lower class will be proud of Pei Yu, and even have the saying that "the gentleman has no reason to go to the body." As China's national strength continues to increase, the people's economic income continues to increase, and the requirements for spiritual culture are getting higher and higher, Hetian jade will become the focus of the collection, with broad development prospects.
3. Hetian jade has abundant reserves, which provides a solid material foundation for the long-term development of Hetian jade industry.
The reserves of Hetian jade are the basis for the development of Hetian jade industry. According to the survey, only the Hetian jade belt in Xinjiang is more than 1,000 kilometers long. At present, there are more than 20 proven mine sites, and the reserve is conservatively estimated to be nearly one million tons. A considerable number of reserve mines are available for mining and can be mined from existing reserves for hundreds of years. The abundant reserves have laid a solid material foundation for the long-term sustainable development of Hetian jade industry.
As a carrier of the spirit and culture of the Chinese people, Hetian jade has received much attention from ancient times to the present. It has also made many other kinds of jade "free-riding", counterfeiting and Tianyu to obtain economic benefits, and common jade that is easily confused with Hetian jade. There are serpentine, quartzite, marble, and glass. When distinguishing jade species, the difference is mainly in terms of gloss, structure, transparency, fracture, appearance, etc. Under laboratory conditions, instruments can be used to detect physical properties such as refractive index and density. Or qualitative analysis of jade directly using large instruments such as infrared spectrometers and Raman spectrometers:
Table 1 Identification characteristics of Hetian jade and similar jade
project name | Sensory identification | Laboratory identification | |||
Refractive index (point measurement) | Density g/cm3 | hardness | The main absorption peak of the fingerprint area of ​​the infrared spectrometer is cm^-1 | ||
Hetian jade | Grease luster, fiber interweaving structure, opaque to translucent, staggered fracture | 1.60-1.61 | 2.90-3.10 | 6-6.5 | 461, 511, 540, 682, 755, 918, 996, 1041, 1089, 1145 |
Serpentine | Waxy luster, blade-like, fibrous interweaving structure, opaque to translucent, jagged fracture | 1.56-1.57 | 2.44-2.80 | 2.5-6 | 484, 556, 670, 1049 |
Quartzite | Glass, silky luster, granular structure, micro-transparent to transparent, smoother fracture | 1.53-1.54 | 2.55-2.71 | 6.5-7 | 471, 635, 687, 779, 797, 1086, 1205 |
marble | Glass luster, granular structure, opaque to transparent, smooth fracture | 1.48-1.66 | 2.65-2.75 | 3 | 709, 883, 1522 |
glass | Glass luster, no structure, common bubbles and agitating lines, opaque to transparent, shell-like fracture | 1.47-1.70 | 2.20-6.30 | 5-6 | 455, 761, 1050 |
(*Infrared spectrometer reflection absorption peak is the main absorption peak of most similar jade, but the absorption peak may increase due to factors such as secondary mineral, jade crystal form, aggregate particle size, sample polishing degree and infrared spectrometer detector. Or weaken.)
Hetian jade is known as the Chinese treasure, and the Kunlun Mountains are the main producing areas of Hetian jade. According to the exploration, the Kunlun Mountains stretch over 1,200 kilometers, and the jade resources are nearly one million tons. The Hetian jade deposit ranks the highest in the world. These mineral resources and mining conditions are not the same, some are to be discovered, some are being mined, others are closed, with the constant spread of Hetian jade culture and people's respect and love for Hetian jade, Hetian jade will be The popularity of the global collection community has important practical significance for the exploration of Hetian jade original ore. In this case, we should promote the advantage of Hetian jade in Xinjiang based on the principle of “reasonable development and resource sharingâ€. world.
