An international team of geologists found 1st fragment of primitive ancient mantle in the vicinity of the sea of Baffin Bay, on the North Anlantic.
A group of canadian and American scientists discovered was unique in its nature a substance which is attributed to the earliest stage of existence of the Earth.
This information is published in the publication Science.
In fact, experts argue that environmentalists have done what was long considered impossible. We are talking about the discovery of the breed, the timing of the appearance which the surface of the Earth is estimated approximately 4.5 billion years.
Remarkable also is the fact that the remains of the primitive mantle of the Earth have been mined in two localities. The first of these is Baffin Bay, in the North Atlantic as well as on the plateau Ontong-Java, in the Pacific ocean. Geologists also noted that the changes, in fact, did not affect any of the discovered species, because it is a unique sample for science is a very serious value.
The age of the samples managed to install in their content of particles of tungsten-182. Scientists have found that the formation of this chemical element coincides with the stage of radioactive decay of the isotope hafnium-182, the existence of which was the place to be in the early stages of the Solar system.
Currently on Earth to meet him is simply impossible. That is why this discovery gives scientists hope that the study found samples will give a more detailed understanding of the processes of formation of the Earth.
