Changbaishan Volcano is a dormant active volcano in northeastern China, located in the southeast of Jilin Province, bordering North Korea. It is one of the largest and potentially threatening volcanoes in China, known for its majestic natural landscapes and rich ecological resources. Changbai Mountain Volcano, located in the Changbai Mountains, on the border between China and North Korea in the east of Jilin Province, the main peak is Changbai Mountain Tianchi Volcano, with an altitude of 27492 meters.
Changbaishan Volcano is the most well-preserved Cenozoic multi-genetic complex volcano in China. The Changbaishan volcano is mainly composed of three large calderas, namely the Twins Mountain Volcano, the Wangswan Volcano and the Tianchi Volcano, and a series of small slag cones.
The volcano is located in North Korea and consists of two mountains, the North and the South, respectively, the South Twin Mountain and the North Twin Mountain, and the highest peak is located in the South Twin Mountain, with an altitude of 2,343 meters. The caldera is an irregular oval shape, due to its early formation age, strong weathering and denudation, so that the volcanic cone part is no longer obvious, but the general outline of the volcanic cone can still be identified on the aerial photographs, the closer to the caldera part of the terrain is steeper, the radial water system will not be very obvious cone depth cut into ridges. The eruption rocks are basalt-rough-faced-alkaline rhyolite series, which conforms to the evolutionary sequence of the Changbaishan volcanic group.
Wangswan Volcano is located 30 kilometers south of Tianchi Volcano, with the highest peak at 20514 meters, the bottom periphery of the bottom of the Wangtian volcanic cone is a large area of basalt lava, surrounding the cone to form a shield-shaped lava platform, its lava flow reaches the Yalu River in the south, crosses the Yalu River in the east, and the north side is covered by the Tianchi volcanic eruption. After the formation of the fire cradle, the swan was subjected to the cutting effect of the water flow, and some of it was not obvious, but the overall outline was clear and irregular oval, the long axis was in the NNW direction, about 20 kilometers long, and the short axis was about 9 kilometers long.
Tianchi Volcano is the youngest of the three volcanic cones, and its caldera is intact and "fresh", with a length of 4 from north to south4 km, 3 km wide from east to west37 km, circumference 131 km. Its cone morphology is well preserved, the four stages of cone formation on the landform are clear, and the Quaternary glacial landform is clearly identifiable.
In addition to the three large composite cones, Changbaishan Volcano also has many small volcanic cones, which are distributed in the wings and plains of the composite cones. Some of the newer volcanic cones are intact, and the spilled volcanic cinders are distributed in layers, mainly composed of red volcanic cinders and volcanic bombs, and some layers contain black lava bands, indicating that the eruption process is alternating between weak and overflow types. The composition of these slag cones is mainly coarse andelite, coarse face rock and alkali flowstone, and the detailed composition of each cone needs to be further studied.
"Changbaishan Volcano" and "Changbaishan" are two different concepts, Changbaishan Volcano is located in the middle of Changbaishan, and the geographical coordinates are 42°01 north latitude', longitude 128°03 E', at an altitude of 2189 meters above sea level. The geographical coordinates of Changbai Mountain are between 41°42 and 42°25 north latitude and 127°40 and 128°16 east longitude. The area of Changbai Mountain Crater Lake (Changbai Mountain Tianchi) is about 9At 820,000 square meters and reaching a maximum depth of 373 meters, the lake is crystal clear and surrounded by steep mountain peaks, creating a magnificent natural landscape.
"Changbaishan Volcano" refers to the active volcano located in the Changbaishan Mountains, Changbaishan Volcano. Changbaishan Volcano is one of the most potentially eruptive large volcanoes in China, with its most recent large-scale eruption occurring about 1,000 years ago.
"Changbai Mountain" usually refers to a mountain range in northeastern China, the boundary mountain between China and North Korea, named for the perennial snow cover on its summit. Changbai Mountain is a vast geographical area that includes natural landscapes such as multiple peaks, valleys, forests, and lakes.
Historically, the Changbaishan volcano has erupted several times, with the most recent eruption occurring in 1903 AD. Although the Changbaishan volcano is currently dormant, it is still considered a potential source of volcanic disasters and requires continuous monitoring and research.
Volcanic eruptions are often followed by abundant mineral resources. There are many mineral resources formed by volcanism, including non-metallic resources and metallic resources. Almost any kind of volcanic rock can be used as a non-metallic resource, and some basalts can be developed as pillar stones, such as the pumice stone of Changbai Mountain. In addition, volcanic ash and volcanic cinder also have a certain value.
In terms of metal resources, copper, gold, silver, uranium, molybdenum, iron and other minerals may occur around the Changbaishan volcano. The formation of these mineral resources is closely related to volcanic activity, which is of great significance for mineral development and economic development.
As one of the important volcanoes in China, Changbaishan Volcano has important geological and ecological value. In-depth research and monitoring will help improve our understanding of volcanic activity and natural disasters, and take corresponding prevention and response measures to ensure the safety of people's lives and property. At the same time, the rational development and utilization of the mineral resources brought by volcanoes can also contribute to regional economic development.
