Gansu province has a complex terrain, including mountains, basins, plains, deserts and Gobi. It is a typical mountainous plateau landform with crisscross mountains and great differences in altitude. Gansu is not only an important birthplace of Chinese civilization, but also a resource-rich province in China. In addition to the natural new sources of animals, plants and water, according to the table of mineral resources reserves in Gansu Province, the producing area of solid minerals is 89 1 one, and among the minerals with proven mineral resources, 10 ranks first in China. In addition, there are a lot of gem resources in Gansu. Next, I will give you a brief introduction!
Qilian Jade Qilian Jade is also called "Jiuquan Jade" because it is mainly produced in Qilian Mountain, Qilian County, Jiuquan City, Gansu Province. According to the mineral composition, color and hue, Qilian jade can be divided into serpentine jade (or Xiuyan jade), nephrite (national standard: Hetian jade) mainly composed of tremolite and monocline, dense jade mainly composed of calcium-aluminum garnet, diopside and plagioclase, jadeite and white jade. Qilian jade is a kind of jade in Qilian Mountain and Altun Mountain.
The development and utilization of Qilian jade has a long history, which first appeared in the Neolithic Age 8,000 years ago. But at present, the most popular Qilian jade in the market is mainly dark green and dark green serpentine jade, and there are a small amount of white seasonal jade and "Qilian Cui Yu" (hydrogrossular) containing green chromite mica, which are mostly practical ornaments and utensils, mostly low-grade jade materials.
In addition, six jade mineralization bodies were found in laojunmiao, Yushugou and Maoyanggou at the northern foot of Qilian Mountain in Sunan Yugur Autonomous County, Gansu Province. Jade deposits are tens of meters to hundreds of meters thick, and the prospective resources of each occurrence are about 654.38 billion tons, which is a large jade mine with great potential for resource development. At the same time, it is found that strange stones are rich in resources, unique in shape and excellent in quality, which are among ornamental stones such as garden ornament and courtyard landscape!
Gansu Nanhong Gansu Nanhong, known as Chiyu in ancient times, first appeared in the Ming and Qing Dynasties and mainly produced in Diebu, Gansu. Jade is moist and delicate, and its color is between big red and orange. Because the primary vein of Gannan red has not been found in Gannan area, most of them pick up some scattered materials in the ravine. Gannan red in the market appears as "old south red" with melon petals and beads, which is of high value and has become a major unsolved case in the jewelry industry. Perhaps in the near future, Gansu South Red Club will appear in front of everyone in another unique way, giving everyone a big surprise!
Taohe inkstone has a long history of development and utilization, and became famous in Tang and Song Dynasties. The royal family treasured it in the Song Dynasty, which was favored by literati. It is the top grade in Four Treasures of the Study and one of the four famous inkstones in China. Taohe inkstone is fine in stone, which does not damage or dry up ink. It is the same as Guangdong Duanyan and Anhui Yu He inkstone.
Yan Tao inkstone is produced in Lama Cliff and Shuiquan Bay on the east bank of Taohe River in Yan Tao Township, zhuoni, Gansu Tibetan Autonomous Prefecture, China. Its mineral composition is mainly diabase. Its texture is delicate and crystal clear, and the stone lines are like silk, like waves rolling and clouds surging. "It should be shaped like a stone, decorated with shapes, and artistically shaped." At present, due to the limited reserves, Taohe inkstone resources are almost exhausted after 1000 years of mining. In addition, the collection of Taohe inkstone is extremely difficult, and there are mountains and cliffs, so Taohe inkstone is even more rare.
Yuanyangyu Yuanyangyu is produced in ultrabasic rocks in yuanyang town, Wushan County, Gansu Province. The mineral composition is mainly serpentine, carbonate, talc, magnetite and chrome spinel. Veins are distributed in Qiujiaxia and Miaoerwan in yuanyang town, Wushan County, Gansu Province, with abundant reserves. The proved reserves of Yuanyangyu in Tianshui, Gansu Province are 324 million, making it the second largest mine in the world.
Yuanyang jade is also called Wushan serpentine jade because its main mineral composition is serpentine jade. Its jade is dense, delicate, shiny and translucent, and its colors are mainly green, dark green, olive green and light green, which reflects the natural texture and is very elegant like dancing dragons and neon lights. It is an excellent jade material for making jade carving crafts.
In addition to the above varieties, Lintao jade in Maxianshan and Yuanyang jade in Wushan, Tianshui also have good development prospects. In addition, Gansu is rich in rare stones and stone appreciation resources, such as noctilucent stone, Yellow River stone, Panggong stone and Yongchang malachite. The mysterious Hexi Corridor, the magnificent Gansu, and many "jewels" are waiting for you to unveil her mysterious veil!
