Aiken Spring, the Devil's Eye in Qinghai
On the Gobi Desert in Mangya City, Qinghai Province, Qaidam Basin, which is more than 200 kilometers away from the northwest of Ganesho Mountain/KLOC-0, there is a spring that takes hot springs all the year round. It is completely different from ordinary hot springs. You can see "Aiken Spring" from the name given to it by local herders. Aiken means "source" in Mongolian. This unusual hot spring, because of its high sulfur content, the birds and animals around the spring dare not approach, and the place where the spring flows is barren.
Around the spring eye, minerals such as sulfur in hot springs have been precipitated for a long time, forming a reddish-brown circle, just like human eyes; The warm water that keeps rolling and overflowing in the center of Yuanyuan looks like a magic eye, with a strange color and a sense of suffocation. Just like its name, it is "the eye of the devil", with association, which makes people feel an indescribable shock.
hot spring
Hot spring is a kind of spring water that naturally gushes out from the ground. The temperature of the spring mouth is obviously higher than the local annual average temperature, and it contains mineral water with trace elements beneficial to human health. At present, there are many areas where wells are drilled manually, generally 600-2000 meters. Groundwater is pumped by deep water pump and is rich in many beneficial minerals. The water temperature is generally above 20 degrees, also known as hot spring well. Because of the different climate, latitude and altitude, it is difficult to unify the lower temperature limit of hot springs.
Reasons for the formation of hot springs
One is formed by magmatism in the crust, or accompanied by volcanic eruption. In the dead volcanic terrain where volcanic activity has occurred, the crustal plate movement makes the surface uplift, and there is still uncooled magma underground, which will continuously release a lot of heat energy. Because of the heat concentration of this kind of heat source, as long as there are pores in the nearby water-bearing rocks, they will not only be heated into high-temperature hot water, but also boil into steam, mostly sulfate springs.
The second is formed by the infiltration and circulation of surface water. That is to say, when the rain falls to the surface and penetrates downward, the aquifer deep in the earth's crust forms groundwater (sandstone, conglomerate, volcanic rock, these good aquifers). Groundwater is heated by geothermal energy below to become hot water, and deep hot water mostly contains gas, mainly carbon dioxide. When the temperature of hot water rises, if there is a dense impermeable rock above it to block the way, the pressure will be higher and higher, so that hot water and steam are in a high pressure state, and as long as there are cracks, they will rush up. After the hot water rises, the closer it is to the surface, the pressure will gradually decrease. As the pressure gradually decreases, the gas contained in it will gradually expand, reducing the density of hot water, which is more conducive to the rise of hot water. The rising hot water circulates repeatedly with the pressure (hydrostatic pressure difference) generated by the density difference of the cold water that sinks and heats later, resulting in convection. When the resistance of the open fracture is small, hot water rises along the fracture and gushes out of the surface, so that hot water can rise endlessly and finally flow out of the surface to form hot springs. With the topography of high mountains and deep valleys, the surface water at the bottom of the valley may be higher than that of high mountains, and the groundwater level is in the middle and lower levels. Therefore, the bottom of the deep valley may be the place with the largest hydrostatic pressure difference, and the possibility of hot water rising from the bottom is the greatest. Most hot springs appear on the river bed of the valley.
