Scientists have recently discovered a mud volcano group in Xinjiang. Experts say this is the largest mud volcano group discovered in China at present. Experts from the College of Resources and Environmental Sciences of Xinjiang University discovered 36 erupting mud volcanoes at the foot of the northern slope of Tianshan Mountain when they visited the tourism resources of Wusu City a year ago. After being confirmed by research, they announced this discovery to the outside world. "Judging from the information currently available, this is the largest mud volcano group discovered in China." Xiong Heigang, deputy dean of the School of Resources and Environmental Sciences of Xinjiang University, said. These mud pits are concentrated in the range of less than 0.5 square kilometers near Baiyanggou town, with the largest diameter of 1.6 meters and as small as broad beans. Mud volcanoes erupt in different shapes, such as round and oval, and some are as deep as 1 m. The natural gas and mud ejected from the underground are constantly churning at the erupting mouth, and the erupting mountain pass erupts more than 60 times per minute. There are two kinds of ejecta: cyan and maroon, and some are covered with black oil. Experts say that about 6,543,800 years ago, under the action of compressive stress, the mud formed by the mixture of groundwater, gas and soft rock stratum washed through the tertiary mudstone deposition and intermittently ejected from the ground along faults and cracks, forming a natural wonder of mud volcano. Where mud volcanoes were found, a large number of fossils were also found. "Mud volcano and volcanic eruption lava are essentially different, but they are similar in formation process," Professor Xiong Heigang said. "From the perspective of eruption intensity, Wusu mud volcano has entered a weak period, and the eruption of mud volcano is at normal temperature." Experts say that mud volcano is a rare natural landscape formed by fault activity. Only a few countries in the world, such as the United States, Mexico and New Zealand, also have mud volcanoes in Kaohsiung, Taiwan Province Province, China, but they are not the same as those found in Xinjiang in scale and quantity. Although these mud volcanoes are surrounded by local Mongolian and Kazakh herders with wooden fences and carefully avoided to avoid livestock falling into them, they are undoubtedly unique and attractive resources for local tourism. The tourism development plan of Wusu City, which is being formulated, plans the protection and development of mud volcanoes. The erupting Wusu mud volcano group can show people the mystery of crustal activity, the strange information in the deep underground and the magical natural landscape.
