A team of researchers from the University of São Paulo, Brazil, made a shocking discovery: a giant island in the Atlantic Ocean. This is a historic finding due to its characteristics.
The conclusions of the study have been published in the journal Scientific Reports.
This demonstrated that the Rio Grande Rise is a possible continental basaltic plateau and a chain of submarine mountains now submerged in the South Atlantic Ocean.
Between 40 and 45 million years ago: the giant island in the Atlantic Ocean
About 1200 km off the coast of Brazil, this huge island the size of Spain appeared. They also claim that it is extremely rich in minerals.
According to the research, the territory would be between 40 and 45 million years old.
They found a giant island 1200 km from Brazil.
The work was carried out over a total of ten years. Scientists believe that the island was formed from volcanic activity and drifted across the Atlantic Ocean before sinking beneath the waves.
The samples analyzed in this part of Brazil showed that the main material of this island is red clay, with several minerals typical of alterations in tropical volcanic rocks. Among them, kaolinite, magnetite, oxidized magnetite, hematite, and goethite.
The Rio Grande Rise was considered an international waters area and was under the custody of the International Seabed Authority of the United Nations.
As explained by the newspaper The Sun, this discovery provides new insights into the geological history of the region, and it could also help us better understand the processes that shape islands of this kind.
The geological and environmental relevance
The discovery of this giant island in the Atlantic Ocean not only provides new data on the geological history of the sea, but it could also offer crucial clues to understand how islands of this kind are formed and evolve.
The research suggests that these structures can act as time capsules. Preserving information on climate changes, tectonic shifts, and ecological changes over millions of years.
Another notable discovery in Brazil
Currently, authorities are discussing whether this island can be considered a legally recognized platform of Brazil.
In addition to this island, the country also made another relevant scientific and environmental discovery. Nothing less than a recent lost city in the middle of the Amazon.
The city in question was abandoned and slowly “swallowed” by the Amazon jungle, which allowed its remains to remain intact and hidden until now.
The hidden city in the Amazon.
The authorities in charge of the discovery respond to the project Amazonia Revealed. They seek to integrate this type of construction into the country’s cultural heritage to ensure its protection.
