How hot springs are formed Do you know which hot springs

Hot springs are formed in two ways, one by the underground magma eruption that bakes the underground water flow, and the other is formed by the infiltration cycle of surface water.

Most hot springs are formed by underground lava eruptions, so hot springs are dangerous. Hot springs formed by the infiltration and circulation of surface water are much safer than those formed by underground magma eruptions, and are often known as tourist attractions.

Conditions for the formation of hot springs.

1. There must be hot water underground (there is a heat source underground).

2. There must be a hydrostatic pressure difference that causes the wild water to gush up (there are cracks in the rock formation that allow the hot spring to gush out).

3. There must be deep sources and long fissures in the rock to reach the ground (there is space for storing hot water in the formation).

Generally speaking, the formation of hot springs can be divided into two types: one is formed by magma in the earth's crust, or accompanied by volcanic eruptions, the extinct volcanic terrain area where volcanic activity has been carried out, and the surface uplifted by the movement of the earth's crustal plates, and the uncooled magma underneath it, all of which will continuously release a large amount of heat energy. Due to the concentration of heat from this type of heat source, as long as there are porous aquifers nearby, not only will it be heated into hot water, but most of it will boil into steam.

The other is formed by the circulation of surface water infiltration. That is, when rainwater falls to the surface of the earth, it infiltrates downwards and deepens into the aquifers deep in the earth's crust to form groundwater. When the temperature of the hot water rises, if there is a dense and impermeable rock formation on the top, the pressure will be higher and higher, so that the hot water and steam are in a high-pressure state, and they will rush up as soon as there is a crack.

As the hot water rises, the closer it gets to the surface, the pressure gradually decreases, and the gas contained in it gradually expands due to the gradual decrease in pressure, reducing the density of the hot water, and these expanded vapors are more conducive to the rise of hot water. The rising hot water and the cold water that is heated later due to the difference in density repeatedly circulate to produce convection, and under the condition that the resistance of the open fracture is small, the hot water can rise and gush out of the surface through the fracture, and finally flow out of the ground to form a hot spring.

How are hot springs formed? Hot springs are produced from underground natural springs with a temperature significantly higher than the local average annual temperature, and mineral springs that contain trace elements that are beneficial to human health. There are also many areas where wells are dug manually, generally around 600 meters, and groundwater is pumped with deep pumps.

Rich in beneficial minerals. The temperature of the hot spring water is generally above 20 degrees Celsius, and it is also called a hot spring well. Due to the differences in climate, latitude and altitude, it is difficult to unify the lower temperature limit of hot springs.

What are the benefits of hot springs? Acidic carbonate springs: volcanic hot springs form gray mud, and spring mud can whiten the face**.

Acid sulfate chloride springs: curative against ** disease. Acid Sulphate Chloride Springs:

It is effective against ** disease. Acid sulphate springs: ** disease, rheumatism, women's disease, athlete's foot.

Acidic sulphate springs: chronic ** disease. Alkaline bicarbonate springs:

Neuralgia, rheumatism, arthritis, etc. Weakly alkaline carbonated springs: **disease, rheumatism, arthritis; Weakly alkaline carbonate springs:

neuralgia, ** disease, arthritis; Colorless and tasteless drinks. Weak alkaline sulfate springs: neuralgia, anemia, chronic poisoning have an improving effect.

Sulfur carbonated springs: chronic diseases such as neuralgia, skin diseases, arthritis. Bicarbonate Springs:

Neuralgia, ** disease, arthritis, athlete's foot. Sulfur carbonate springs: neuralgia, anemia.

Low-temperature neutral bicarbonate springs: chronic ** disease. Neutral carbonated hot springs:

Disease, rheumatism, women's disease, and foot gas. Chloride Spring: The water quality is smooth and smooth, and it can treat ** diseases, rheumatism and neuralgia.

What are the types of hot springs? Volcanic hot springs. When the rain falls on the surface of the earth, seeps down into the depths of the earth's crust, under the action of high heat and pressure, the cracks rise and gush out of the surface, and the temperature is still higher than the human body, the so-called hot spring is formed.

There are many types of fountains, some silent, some rushing out huge hot water, and some hot water gushing out together with mud and natural gas. Volcanic hot springs are non-volcanic hot springs, including deep castle rock hot springs, metamorphic rock hot springs, and sedimentary rock hot springs. That is, through physical exploration and geological analysis, the depth of the aquifer generated by geothermal heat is calculated, and the geothermal areas where hot spring development is likely are carried out, and hot spring water is collected from deep fault zones.

Hot springs are classified into three grades according to their temperature: high temperature, medium temperature, and low temperature. According to the different acidity and alkalinity of hot water, it can be divided into three categories:

Those with a pH value lower than 6 to 6 are acidic hot springs, and those with a hydrogen ion concentration greater than 8 are alkaline hot springs. A pH between 6 and 8 is considered a neutral hot spring.

How are hot springs formed?

One is formed by magmatism in the earth's crust or accompanied by volcanic eruptions.

Volcanically active extinct volcanic terrain areas, the surface uplifted by the movement of crustal plates, and the uncooled magma underneath the earth, will continue to release a large amount of heat energy.

The second is formed by the infiltration cycle of surface water.

Famous Hot Spring Spots:

Guangxi Shangsibu Hot Spring:

Surrounded by mountains on three sides, it is located in a deep valley, with layers of forests and green, clouds and mist, and the natural environment is very beautiful.

Butou Hot Springs is a natural mineral water hot spring with a unique "blue color", which is different from the milky blue of the Blue Lagoon in Iceland; The "blue" of the hot springs is transparent and pure.

The patchwork of blue hot springs is distributed in the green mountains and green waters, which has a high appreciation value and is one of the most beautiful hot spring tourist attractions in China.

Shiqian Hot Spring: Shiqian Hot Spring is a hot spring tourist resort and a national hot spring group scenic spot, where the hot springs have a history of more than 400 years, and can be bathed and drunk directly. The hot spring is located in "Shiqian County, Guizhou", which organically integrates the idyllic scenery of mountains and rivers and the characteristic ethnic cultural elements.

Tengchong Volcanic Atami Hot Springs:

Atami Hot Springs is built on the mountain, with an excellent natural environment, and visitors are exhausted by the cherry blossom spring bathing spring with chirping birds and gurgling water. When you first enter the Atami, it is like stepping into the fairyland of Yaochi, the eyes are full of green and verdant, the hot spring gushes out from between the mountains and rocks, the hot smoke rolls out, and the whole mountain forest is shrouded in a white mist, such as a dream of demolishing the acre.

Formation of hot springs

Hot spring water'The formation is the formation of atmospheric precipitation infiltrating deep into the earth's crustal faults, and after decades of evolution and infiltration after contact with underground hot magma, it is finally transferred to the surface.

Types of hot springs

Hot springs are classified according to the environment in which they are located, and they can be classified as volcanic and non-volcanic hot springs.

Volcanic hot springs.

When rainwater falls to the surface and penetrates down into the earth's crust, it rises and gushes out of the surface through the cracks after being subjected to high heat and pressure, and the temperature is still higher than the body temperature of the human body, which is the so-called hot spring. There are many forms of gushing out, some silently and slowly, some rumbling and spurting, and some are hot water gushing out with mud and natural gas.

Non-volcanic hot springs

Non-volcanic hot springs include plutonic hot springs, metamorphic rock hot springs, and sedimentary rock hot springs. In other words, through physical exploration and geological analysis, the depth of the aquifer generated by geothermal heat is calculated, and the hot spring water is extracted from the deep fault zone by drilling in the geothermal area where there is a possibility of hot spring development.
