More and more researchers are trying to know how the evolution of the Earth has been with the passage of the centuries and One of the last studies has shed light on a large island.
A group of researchers from the University of São Paul Possible Continental Basaltic Plateau.
Scientists say that it is a chain of submarine mountains in the South Atlantic Ocean. Experts have assured that it is about 1,200 kilometers from the coast of Brazil.
In the article published in the magazine they assure, after ten years of research, that the size of this plateau It is from the same surface that Spain has today.
The researchers came to detect the presence of red clays with some minerals, such as caolinite, magnetite, oxidized magnetite, hematite and Goethita, which are typical of the tropical alteration of volcanic rocks, according to the FAPESP agency.
In addition, the researchers also analyzed mineralogical, geochemical and magnetic characteristics of a different red clay sample extracted from a depth of water of around 650 meters.
The IO-USP professor Luigi Jovane, a work supervisor, explained to the agency that the investigation served to “define exactly the presence of the island, and what is being Discussing now is whether this area can be included in the Brazilian continental platform“.
“Geologically, we managed to discover that clays were formed after the latest volcanic activities recorded 45 million years ago, that is: their training passed between 30 million and 40 million years ago. And would have occurred as a result of tropical conditions“He said.
The elevation of Rio Grande was considered an international water zone and was under the custody of the United Nations International Marine Funds. But Brazil made an extension application beyond 200 miles in the area. “It is essential to understand ecosystem services and natural processes that act in the elevation of Rio Grande“, Razonó Jovane.
