Using powerful acids, the researchers dissolved pieces of limestone that had formed at different times, corroding everything except chromite – a hardy mineral found in some meteorites.
But instead there was only one peak during the last 500m years. The researchers speculate that asteroid smashes have to occur in a specific place for their fallout to interact with Earth.

Scientists Figure out how the Asteroid Belt Attacked the Dinosaurs - Universe Today
How do you track an asteroid that hit the Earth over 60 million years ago? By using a combination of geology and computer simulations, at least according to a team of scientists from the Southwest Research Institute ( SwRI ).
Large creatures like dinosaurs having evolved at all, and their reigning over the Earth for hundreds of millions of years, shows that such large impacts were not very common in their time – so where did the impactor come from? Turns out it was probably from the outer asteroid belt.
Two Bizarre red Asteroids Somehow Migrated From the Kuiper Belt all the way to the Main Asteroid
If asked to pick what color asteroids in the asteroid belt would be, red is likely not one that would come to mind for most people. But that is exactly the color of two new asteroids found by Hasegawa Sunao of JAXA and an international team of researchers.
The two asteroids, known as 203 Pompeja and 269 Justitia, were originally thought to be D-type asteroids, are rich in silicates and carbon, and make up the majority of the Jupiter Trojan asteroids that orbit behind the giant planet.
Immensely large asteroid to pass dangerously close to Earth this month | TweakTown
A massive meteor is slated to pass dangerously close to Earth this month, and according to researchers, you will be able to spot it if you have the right equipment.
The asteroid is named 2016 AJ193, and according to reports, it's estimated to be just under a mile in diameter and is traveling at a ridiculous 58,538 miles per hour. NASA has dubbed the asteroid " possibly dangerous ". However, EarthSky has said that the asteroid won't impact Earth.
China will send student experiments into deep space on 2 upcoming missions | Space
China's upcoming exploration mission to the lunar south pole will carry one of more than 500 experiments designed and submitted by students across the country.
China is planning to launch its Chang'e 7 spacecraft around 2024. It will include a lander, rover, orbiter, relay satellite and a small hopping spacecraft to explore the rough terrain of lunar craters.
