Reveal another world 4.5 billion years old that was swallowed up by the Earth

Two mysterious continents, possibly the first parts of the earth or the ocean floor of the early earth, have just been discovered . in our gluttonous planet.

A new study published in the scientific journal Journal Geochemistry, Geophysics, Geosystems has revealed an unbelievable " underground world" that is about the same age as Earth itself: 4.5 billion. five years old.

Geologist Curtis Williams (University of California-Davis, USA) and his colleagues used the models to search for the location and origin of volcanic rock samples collected from around the world. They all led them to the mysterious world of two solid stone continents buried in the deep cover of the planet , hundreds of miles off the ground.

These may be the oldest parts of the Earth . Research also shows that they can be formed from an ancient magma ocean, so extremely solid. These two continents could be either solid land or bottoms of the early ocean, surviving the turbulent volcanic history of the young earth and the hypothetical collision of Theia. moon.

But in the end, it is the earth that ends this ancient land itself with the process of subduction: our planet literally swallows part of its crust, literally ! These ancient lands were buried hundreds of miles deep and became the forgotten world throughout much of planet history.

Meanwhile, deep tectonic plates have the opportunity to emerge to the surface and create new crust for our planet. Throughout 4.5 billion years of history, the Earth has swallowed the land many times , with the most evident evidence being that traces of oceans were swallowed, resulting in continents reuniting as supercontinent and then being swallowed up. tear many times.

According to the researchers, this new discovery provides more data for geologists to better understand the ancient tectonic activities that contributed to the creation of the Earth with the face it is today.
