According to Indian media, Chinese scientists have found a new 1850-meter diameter and 150-meter-deep crater, the Yilan Crater, in Harbin, Heilongjiang Province. The crater is located on the western edge of the Sanjiang Plain, in the low hills of the southern foothills of Xiaoxing Anling. The Elan crater shows a strange topographical feature, and the southern edge of the crater has been subjected to large-scale erosion and handling of the pit, resulting in the loss of about one-third (2 km) of the total length of the pit. Most of the area of the pit is covered by birch trees.
The results show that the Elan crater formed on the granite bedrock of the Cretaceous period, but the exact time of its formation needs further study. At the same time, lake sediments at the bottom of the crater suggest that there was once a lake that disappeared about 10,000 years ago.
Chen Ming pointed out that the discovery of Theland Crater is of great practical significance, one is to provide a valuable “natural crater laboratory” for planetary science and geology research in China, the other is to reveal new evidence of the history of low-altitude glaciers in northeast China, and the other is the location of different tectonic slots of Elan craters and previously discovered craters. It is shown that the possibility of discovering new craters in China still exists, and the fourth is that the craters and the remains of glaciers belong to the popular science knowledge and geological landscape, which is conducive to the construction of a characteristic popular science education base or museum.
