Undoubtedly, at least at the beginning of Hadean, the earth was covered by an ocean.Although global and eventually forming a crust, volcanic activity and bombing as well as We must turn our planet into a hell worthy of at least a hundred million years for the Greek god Hades.
Will the first ages of our planet be unfit for life? Is there nothing left in this hellish age? Are we sure? Then, how did a “ball of fire” become a known, ocean-covered planet … In nine minutes, unfortunately, the recently deceased geologist Herv Martin gives you the keys to decoding the ecosystem of primitive Earth. . © French Society of Exobiology
Two researchers from Yale and Caltech Universities in the United States, Yoshinori Miyazaki also published in the popular newspaper An interesting article by The global transformation of primitive earth caused it to pass from one ball to another Powered by Blogger Over a period of about 500 million years. Their work brings with it a new perspective on falling into the trap of carbon dioxide and the fact that Earth has become a habitable and inhabited planet, which it is not today. If one does not believe the arguments about what is possible .
Disappearing Exotic Pyroxenites
Korenaga and Miyazaki now argue that during the Hadian period, rocks that did not exist today reacted with water.According to geochemical processes, the Earth’s atmosphere was 100,000 times richer Than today.
Rules ofFluid mechanics and that And some In Hedian modeling, the Earth’s interior is constructed using the atmosphere Two geologists point out that particularly rich rocks saved the Earth from hell with a surface temperature of over 200 degrees Celsius. Belongs to a large family of pyroxenes – from the Greek Fire (Fire) and Foreign (Stranger): “Stranger in the Fire” -, They are common components of igneous and metamorphic rocks found on Earth today.
These foreign rocks, which no longer exist, were particularly richAccording to researchers who cover our planet and give it a dark green color, such rocks (pyroxenite) must react with CO.2 Provides carbonates.
But the new model of the Coronaga and Miyazaki, TheThe heat and convection of the Hadith In combination with these exotic pyroxenites, carbon dioxide is released 10 times faster than previous mantle models. . It will only take 160 million years.
As a bonus, as noted in a press release from Yale University, the interactions of the first ocean waters with the now extinct pyroxenites will be similar to those observed today at the famous level. (Lost city) in the middle of the Atlantic.From
