CCTV international news: on the way to the no man's land, the scientific research team of qiangbei no man's land encountered the largest intermittent geothermal fountain in Asia when passing through ANGREN County, Tibet. This world wonder aroused the strong interest of scientific experts
the nearly 100 eye fountains here have boiling springs, geysers, hot gas springs and other forms, of which the largest geyser erupts the highest every few seconds, The direction of the fountain "DSM's advanced materials have helped us achieve excellent sales deeds and different shapes. Some are vertical and some are oblique, with a maximum range of more than 10 meters. The temperature of the spring is as high as 86 degrees, and the amount of water ejected per second is about one ton.
Dorje, chief engineer of the Tibet geothermal survey team, said: "These fountains go down after spraying once. After the cold water goes down, it needs a heating process. After heating, it reaches a certain pressure, and then sprays out when the pool reaches saturation."
after field observation and calculation, relevant experts found that there were certain differences between the results of these springs at present and those observed more than ten years ago. Dorjee said: now in the Qinghai Tibet Plateau, geothermal activity is now in a relatively strong period after unloading. For example, the changes of spring valleys and spring flows in this geothermal display point are constantly changing. Compare the differences between before and after manufacturing personalized products that customers need. The biggest change is the change of head height. The reasons for the change are: first, human factors lead to the change of underground air chamber, and second, the reduction of surrounding water supply. It can be seen from the observation of the fountain that the geothermal activity in this area is still very strong. According to the study of geothermics, magma is hidden in the deep of the geothermal belt along the east-west direction of the Yarlung Zangbo River, and the activity is intense
strings of pearly crystals can be seen at the place where the water drops fall to the ground. According to experts, these are precious cesium Sihua. The spring water contains high concentrations of cesium, potassium, arsenic and other chemical elements. Arsenic is commonly known as arsenic, so the spring water contains high toxicity. Experts warned passers-by that it is best to watch the fountain from a distance, not to touch the fountain, let alone drink. It is understood that recently, due to local residents building houses and drinking water and washing mines, the pressure of the fountain has decreased, and the fountain degree has decreased significantly, which has seriously affected the fountain landscape. In order to maintain this strange natural landscape, the Tibet Autonomous Region has identified tage fountain as a district level nature reserve at the beginning of this year.
