"Scientists Confirm Ancient Meteorite Split Mountain Top in Two"

Scientists have confirmed that the two peaks of Baijifeng Mountain in northeastern China were formed by a meteorite impact millions of years ago. The impact created a 1.6-kilometer-wide crater, splitting the mountain into Front Baijifeng and Rear Baijifeng. The discovery was made through the analysis of rock fragments known as "celestial stones" found in the area. The rocks contain quartz minerals that show evidence of shock metamorphism, indicating a meteorite impact. The exact timing of the impact remains unknown, but comparisons with another impact site suggest it could be relatively recent. Further research is needed to determine the age of the impact.

Unearthing China's Historic Mountaintop Impact Crater

Chinese scientists have discovered the world's first confirmed mountaintop impact crater on Baijifeng Mountain in northeastern China. The impact, caused by a meteorite, split the mountaintop into two peaks and left a circular depression. The mountain is covered in rock fragments known as "celestial stone," which exhibit shock patterns consistent with an impact. The exact timing of the impact is unknown, but it likely occurred after the formation of the granite that makes up the crater, which is between 150 million and 172 million years old. This discovery adds to the limited number of confirmed impact craters in China.
