When an asteroid meets a mineral: a fantastic dive into matter!

Scientists are trying to date (thanks to the U-Pb method) precisely the moments when asteroids have impacted the Earth. The idea is to link these impacts to possible environmental catastrophes that they would have initiated. To do this, we are looking for clues preserved in the rocks that were shocked during the impact on Earth. These clues are identifiable in the minerals on a very small scale (a few nanometers) and testify to the intense deformations that the material underwent during the impact.
