CTOnews.com, September 10, according to Xinhua News Agency, Chinese scientists have found a crater on a high mountain for the first time. It is located at the top of Baijifeng National Forest Park, more than 20 kilometers southeast of Tonghua City, Jilin Province, with a diameter of 1400 meters. The height difference between the highest point on the edge of the crater and the lowest point in the center of the crater is more than 400m.

▲ Tu Yuan Xinhua News Agency, Chen Ming, a scientist who discovered the crater and a researcher at the Beijing High pressure Scientific Research Center, said in an interview that Baijifeng Mountain is mainly composed of bedrock materials such as Proterozoic sedimentary rocks and Jurassic granite. When an asteroid hits the earth's plane, it forms a bowl-shaped crater. However, when an asteroid falls on a special terrain on the earth's surface, the propagation pattern and mechanism of the shock wave at the explosion point will change with the topography (such as the direction of the mountains).

As for the shape of Baijifeng Mountain, it is also caused by the violent explosion caused by the asteroid hitting the top of the mountain and the ejection of rocks in the target area, and the impact crater has created two new peaks, "former White Chicken" and "back White Chicken". According to reports, the discovery solved the mystery of why the Baiji Peak is covered with a large number of "heavenly rocks".

CTOnews.com Note: a crater is a crater formed by the fall and impact of asteroids and other celestial bodies in the universe, and it is also one of the important bases for scientists to study outer space.

According to previous reports by CTOnews.com, another crater in northeast China was found to be the largest impact on Earth in nearly a hundred thousand years-the Yilan crater in Yilan County, Harbin in the central and southern part of Heilongjiang Province. Its formation is related to the hypervelocity impact of a 100-meter-diameter asteroid, which released more than 10 million tons of TNT explosive equivalent, causing a powerful explosion.
