Earth's most ancient impact craters are disappearing

Impact Craters

WASHINGTON — Earth's oldest craters could give scientists critical information about the structure of the early Earth and the composition of bodies in the solar system as well as help to interpret crater records on other planets. But geologists can't find them, and they might never be able to, according to a new study. The study was published in the Journal of Geophysical Research Planets, AGU's journal for research on the formation and evolution of the planets, moons and objects of our Solar System and beyond.

Geologists have found evidence of impacts, such as ejecta (material flung far away from the impact), melted rocks, and high-pressure minerals from more than 3.5 billion years ago. But the actual craters from so long ago have remained elusive. The planet's oldest known impact structures, which is what scientists call these massive craters, are only about 2 billion years old. We're missing two and a half billion years of mega-craters.

The steady tick of time and the relentless process of erosion are responsible for the gap, according to Matthew S. Huber, a planetary scientist at the University of the Western Cape in South Africa who studies impact structures and led the new study.

"It's almost a fluke that the old structures we do have are preserved at all," Huber said. "There are a lot of questions we'd be able to answer if we had those older craters. But that's the normal story in geology. We have to make a story out of what's available."

Geologists can sometimes spot hidden, buried craters using geophysical tools, such as seismic imaging or gravity mapping. Once they've identified potential impact structures, they can search for physical remnants of the impact process to confirm its existence, such as ejecta and impact minerals.

A fireball with a trail of light illuminated the sky on the night of Tuesday, July 25, and was seen in the states of Colima, Jalisco, and Michoacán.
A fireball with a trail of light illuminated the sky on the night of Tuesday, July 25, and was seen in the states of Colima, Jalisco, and Michoacán.
In Colima, Jalisco and Michoacán hundreds of people witnessed the passage of an impressive fireball in the sky during the night of this Tuesday, July 25.

Videos circulating on social networks show the moment when a huge fireball lights up the sky, then a loud roar is heard.

The phenomenon is a fireball with a trail of light that crossed the sky at 9:40 p.m.

In the different videos recorded by citizens, you can see that the fireball fragments and the little pieces look like fireworks.

Daytime meteor streaks across the sky of Paraíba and Rio Grande do Norte, Brazil on July 24

mmmmm
Clima ao Vivo cameras recorded for the third time the daytime meteor that occurred this Monday (24th), which crossed the sky of Paraíba and Rio Grande do Norte. According to Bramon, daytime meteors are rare events, because to be visible they need to be large, otherwise they are overshadowed by daylight.
