When was the Tianchi of Changbai Mountain formed?

Formation. Changbai Mountain Tianchi, also known as Baitou Mountain Tianchi, is located in the southeast of Jilin Province, is the boundary lake between China and North Korea, and the northern part of the lake is in Jilin Province. Changbai Mountain is located on the border of China and North Korea, with magnificent momentum, rich resources and very beautiful scenery.

In ancient times, Changbai Mountain was originally a volcano. According to historical records, it erupted three times since the 16th century, and when the volcanic eruption ejected a large amount of lava, the crater formed a basin. The lava material from the eruption piled up around the crater and formed 16 peaks, seven of which are in North Korea and nine in China.

Each of these 9 peaks has its own characteristics and forms a bizarre landscape.

Historical records record that Tianchi water "no ice in winter, no ping in summer", Xia Wuping is true, but not ice in winter, the ice layer in winter is generally thick rice, and the freezing period is long.

Six or seven months. However, there are many hot springs in the Tianchi, forming several hot spring belts, 150 meters long, 30-40 meters wide, the water temperature is often kept at 42, it is steaming in the middle of winter, the ice melts and the snow melts, so some people call the Tianchi warm and cool again.

Although Tianchi is surrounded by peaks, the altitude is only 2194 meters, but it is the highest crater lake in China. It is generally oval in shape, with a length of kilometers from north to south and a width of kilometers from east to west, with an area of square kilometers and a circumference of kilometers. The water is very deep, with an average depth of 204 meters and a maximum depth of 373 meters, which is the deepest lake in China, with a total storage capacity of 100 million cubic meters.

I wish you progress in your studies and go to the next level!

If you don't understand, please ask in time, satisfied, o( o thank you.)

If Qinghai Lake was formed between 200,000 and 2 million years ago, then Changbai Mountain Tianchi is no more than 200,000 years old. Because Qinghai Lake is salty, it means that during the formation period of Qinghai Lake, there was salt and alkali on the ground and underground. The water of Tianchi in Changbai Mountain is light, which shows that the salinity on the ground and underground has entered the sea through the infiltration and flow produced by precipitation when Tianchi is formed, so that there is no saline in the ground and underground, so the water of Tianchi is fresh water.

Otherwise, the error of the age of Qinghai Lake is too large, that is, freshwater lakes can only be formed or produced after saltwater lakes.

It should be emphasized above that no more than 200,000 years is the age of Tianchi in Changbai Mountain, not the age of Changbai Mountain. Because Changbai Mountain Tianchi is not formed by volcanic eruptions, that is, the capillary phenomenon produced by erupted magma, it is difficult to produce and maintain the water of Changbai Mountain Tianchi. The Changbai Mountain Tianchi is that there are soluble substances under the mountain, such as saline, etc., which seep water on the top of the mountain for hundreds of millions of years, and form the shape of the Tianchi under the erosion of the underground river for hundreds of millions of years, and then through the action of the stress on the top of the mountain for hundreds of millions of years, the top of the mountain collapses, and the shape of the underground Tianchi is cloned to the top of the mountain, becoming today's Changbai Mountain Tianchi, so the age of the Tianchi of Changbai Mountain is up to 200,000 years.

Changbai Mountain TianchiYesVolcanic eruptionsWhen the volcanic eruption ejects a large amount of lava, the crater forms a basin, and after a long time, the water accumulates into a lake, and it becomes the current Tianchi.

Through the detailed investigation and study of volcanic geology, Changbai Mountain is a Cenozoic complex volcano of multiple genesis, and the Tianchi on the top of the mountain is the crater. Volcanic activity has gone through the stages of shield building 277-1.2 million years ago, cone building 1.12-40,000 years ago, and eruption of three acres in the past 10,000 years.

According to historical records, it erupted three times since the 16th century, and when the volcanic eruption ejected a large amount of lava, the crater formed a basin, and after a long time, the water accumulated into a lake, and it became the current Tianchi. And volcanic eruptions.

The lava material that came out of it was piled up around the crater and formed 16 peaks standing around it, 7 of which are in Korea and 9 in China.

Introduction to Tianchi in Changbai Mountain

Changbai Mountain was formed by geological orogeny 12 million years ago, and after many eruptions, it expanded into a giant umbrella body, and when the volcano was dormant, the spring overflowed, forming more than 10 square kilometers.

of the vast surface of the water. The elevation of Tianchi is meters, slightly elliptical, thousands of meters long from north to south, and kilometers wide from east to west. The catchment area, the water surface area, the circumference of the water surface is kilometers, and the deepest point is 373 meters.

The total water storage capacity is 100 million cubic meters. The water temperature of Tianchi is the average annual temperature. Like a magnificent piece of jasper embedded in the majestic peaks of Changbai Mountain, Tianchi is the largest volcanic lake in China and the deepest alpine lake in the world. It is now the boundary lake between China and North Korea.

Changbai Mountain Tianchi was formed in 12 million years before the geological orogeny, after many eruptions and expanded into a giant umbrella body, when the volcano is dormant when the spring overflows, forming more than 10 square kilometers of vast water surface, Tianchi is meters above sea level, slightly elliptical, north and south long thousand meters, east and west wide thousand meters.

Changbai Mountain Tianchi is located at the top of the volcanic cone of the main peak of Changbai Mountain, Erdaobaihe Town, Antu County, Yanbian Korean Autonomous Prefecture, is a dormant volcano, the crater accumulates water into a lake, the water of the summer melt pond is more blue than the sky, and the frozen ice surface is as white as snow in winter.

The crater walls around Cheonchi are steep and form more than a dozen ring-shaped peaks, all of which are above 2,500 meters above sea level, among which the General Peak is the highest, with an altitude of 2,749 meters, and is located on the closed side of North Korea.

Changbai Mountain is a famous mountain in China, which has been China's sacred territory since ancient times, and is the birthplace of the three rivers of Songhua River, Tumen River and Yalu River.

There is only 1 Tianchi in Changbai Mountain.

Changbai Mountain Pool in the Sky, also known as Baitou Mountain Pool, is located in the Changbaishan Nature Reserve in the southeast of Jilin Province, and is the boundary lake between China and North Korea, with each side owning a portion of the water. Tianchi is about 4,400 meters long from north to south, about 3,370 meters wide from east to west, the altitude of its pool water is meters, the deepest point is 373 meters, the average is 204 meters, the water surface area is square kilometers, and the circumference is kilometers. According to the record of "Changbai Mountain Jianggang Zhiluo":

Tianchi is in the center of the peak of Changbai Mountain, surrounded by peaks, about 20 miles high from the ground, so it is called Tianchi Danna. ”

Changbai Mountain Tianchi is the most intact Cenozoic multi-genetic compound volcano in China, Tianchi has eruptions after the Song Dynasty, since the 34th year of Guangxu in the Qing Dynasty (1908), Liu Jianfeng climbed Baiyun Mountain, named the sixteen peaks of Tianchi, and found out the headwaters of the three rivers of Yalu, Songhua and Tumen Mobu. The crater wall around Tianchi is steep, and forms more than a dozen ring-shaped mountain peaks, the altitude is above 2500 meters, Changbai Mountain Tianchi is also the birthplace of Songhua River, Yalu River and Tumen River, known as the "source of the three rivers".

There are 3 Tianchi in Changbai Mountain: Changbai Mountain Tianchi, Beikeng Tianchi and Nankeng Tianchi.

How many Tianchi are there in Changbai Mountain? Changbai Mountain has a Tianchi.

Summary. It is formed by the crater of the volcanic crater, so the pleasant scenery of Changbai Mountain Tianchi is formed.

Changbai Mountain Tianchi was formed in the geological orogeny of 12 million years ago, after many eruptions and expanded into a giant umbrella body, when the volcano is dormant, the oak jujube spring overflows and closes, forming more than 10 square kilometers of vast water surface, Tianchi is meters above sea level, slightly elliptical, north and south are thousands of kilometers long, east and west kilometers wide.

Changbai Mountain Tianchi is located at the top of the volcanic cone of the main peak of Changbai Mountain, Erdaobaihe Town, Antu County, Yanbian Korean Autonomous Prefecture, is a dormant volcano, the crater is waterlogged into a lake, the water of the summer thaw pond is bluer than the sky, and the frozen ice surface is as white as snow in winter.

The crater walls around Cheonchi are steep and form more than a dozen ring-shaped peaks, all of which are above 2,500 meters above sea level, among which the General Peak is the highest, with an altitude of 2,749 meters, located on the North Korean side.

Changbai Mountain is a famous mountain in China, it has been China's sacred territory since ancient times, and is the birthplace of the three rivers of Songhua River, Tumen River and Yalu River.

The Tianchi of Changbai Mountain was formed by a volcanic eruption.

Changbai Mountain Tianchi, also known as Baitou Mountain Tianchi, is located in the Changbai Mountain Nature Reserve in the southeast of Jilin Province, and is the boundary lake between China and North Korea, with each side owning a part of the water. From the 5th year of the Song Qingyuan Dynasty to the first year of the Song Jiatai Dynasty (1199-1201), the Tianchi Volcano erupted as the largest eruption in the world in nearly 2,000 years, when the eruption of volcanic ash fell as far as the Sea of Japan and northern Japan.

This eruption, a large amount of lava from the eruption of the cave, the crater formed a basin, and after a long time, the water accumulated into a lake, and it became a heavenly pond. In other words, the age of Changbai Mountain Tianchi is no more than 1,000 years.

Main attractions

1. Tianchi

The water of Tianchi Lake is deep and clear, and the surface of the pond surrounded by peaks is colorful and magnificent. The ** season to visit Tianchi is in the middle of summer. The shadows of the 16 mountain peaks and the blue sky overhead are reflected on the edge of the heavenly pond.

2. Changbai Mountain Waterfall

Changbai Waterfall is located in the north of Tianchi Pond in Baitou Mountain, there are sixteen strange peaks around the four key keys of Changbai Pond, there is a gap on the north side, called the U-shaped gate (called the small gate in ancient times), the water of Tianchi flows down from this, because the mountain slope is steep, the water potential is turbulent, at a glance, like a diagonal ladder, people call it Tongtian River, also called "Chengcha River".
