Scientists Unearth Mysterious Meteorite Crater in ChinaNEWS | 15 November 2025I agree my information will be processed in accordance with the Scientific American and Springer Nature Limited Privacy Policy .

Scientists have discovered a massive asteroid impact crater in China. The bowl-shaped depression is some 900 meters wide—more than eight times the length of a football field.
In a paper published last month, the researchers behind the discovery said the structure, named the Jinlin crater, was likely formed by a meteorite hit during the early to mid-Holocene, a geological epoch that started just 12,000 years ago. The findings were published online on October 15 in the journal Matter and Radiation at Extremes.
The analysis is intriguing, but several experts cautioned that more research is needed to confirm that time line.
“The Holocene age estimate is only inferred and not measured, so the age is very uncertain,” says Mark Boslough, a research professor at the University of New Mexico, who was not involved in the study.

Other experts are more sanguine: Geologist Steven Jaret says the team only suggested that the impact most likely occurred during the early to middle Holocene—an estimate supported by the data in the study. Jaret, who was also not involved in the study, emphasizes that the researchers agreed that more work would be needed to precisely date the crater. Scientific American has reached out to the authors for comment.
The team analyzed chemical and physical weathering rates to come up with its age estimate. These measurements are often error-prone, however, Jaret says.
A more precise method would be to measure the rate of decay of radioactive isotopes in the rocks, such as those of the element argon. But this is time-consuming and extensive, Jaret says.
“A lot of times, you need to justify doing the next step,” he says.Author: Claire Cameron. Andrea Tamayo. Source
