How old is the moon really? A new discovery of researchersMoon formed about 4.36 billion ago years, being 200 million years "younger" than scientists thought, according to a recent study on rock monthly scientific journal Nature published Thursday.This calculation results in a new procedure for dating with isotopes of lead and neodymium found in a sample of anortozit, the oldest rocks in the crust monthly.According to one of the most important theories about the formation of the Moon, Earth's natural satellite has emerged from the impact of an object the size of a small planet and Earth.This collision would have pulled large amounts of matter on Earth, rocks and magma, which would be crowded and then to form the Moon. Its surface was initially just a huge ocean of magma that has cooled further."Age extremely small sample of the monthly means either that the Moon solidified significantly later than previously thought or that we must completely revise their understanding of the geological history of the moon," said Richard Carlson of the Institute Carnegie of Washington.If the new monthly sample dating is accurate, this means that the oldest areas of bark and monthly land were formed around the same time, shortly after a huge impact.This age corresponds to the oldest deposits containing terrestrial mineral, zircon found in Western Australia.
