Researchers from USP Identify Two of the Oldest Volcanoes on Earth in Pará, With Almost 1.9 Billion Years and Possible Reserves of Gold and Other Minerals Below Their Structures

Two of the oldest volcanoes on the planet are in Brazilian territory, in the south of Pará. With almost 1.9 billion years, the formations were described by researchers from the University of São Paulo (USP), who released the study in 2002.

They are located between the Tapajós and Jamanxim rivers, in a remote area covered by vegetation. The oldest of them has a rounded hill shape today, with approximately 200 meters in height and 1.7 kilometers in diameter. The other reaches 300 meters in height.

The research conducted by USP revealed that beneath these structures there is an important reserve of minerals. The depth ranges from 100 meters to one kilometer and may contain gold, silver, copper, zinc, and molybdenum.

Before this study, it was common to associate these deposits with geological faults. The discovery showed that the volcanic rocks in the region can also harbor this type of mineral wealth.

Scientists used satellite images, radar, and analyses of the composition of the rocks to reach their conclusions. The results indicated that the area underwent intense volcanic activity during the Paleoproterozoic era and remained active for about 40 million years.

At the time of activity, the volcanoes spread lava and incandescent rocks over thousands of square kilometers. The affected territory extended from the Tocantins River in the east to the far north of the state of Pará.

Today, these volcanoes are extinct. Hidden by the forest, they pose no risk of eruptions.

According to the researchers, the structures are in good condition of preservation. They have hardly suffered erosion or impacts caused by movements of the Earth’s crust, even with the passage of so much time.

A ciência está em constante evolução, porém a mesma não está em condições de sobrepor as leis naturais da terra, desastres naturais podem ocorrer a qualquer tempo já que o homem constrói para ele mesmo ser destruído no futuro. O criador do universo Deus é que sabe aonde e quando esses desastres naturais podem ocorrer.

Two Of The Oldest Volcanoes In The World Are In Brazil, And There May Be Gold And Other Minerals Beneath Their Formations

Researchers from USP Identify Two of the Oldest Volcanoes on Earth in Pará, With Almost 1.9 Billion Years and Possible Reserves of Gold and Other Minerals Below Their Structures

Seven world powers including the US, China, and Russia are spending €22 billion on a reactor in the south of France that aims to confine plasma at 150 million degrees Celsius, ten times the temperature of the Sun’s core, using a magnetic field capable of lifting an entire aircraft carrier.

Elon Musk’s internet comes to mobile: Starlink technology connects smartphones without an antenna via satellite, works even without carrier signal, already costs just US$10 extra in the US, and could arrive in Brazil as an included benefit.

While Brazil has been discussing bullet trains for 16 years, China delivers 5 new high-speed lines in 2026, surpasses 50,000 km of HSR, and moves 1 billion passengers in a single year.

With a wingspan of 152 meters, 76 tires, and a capacity to carry 1,270 tons, the Boeing Pelican was the giant “flying ship” that promised to cross oceans close to the water on an invisible air cushion beneath its wings.

While countries spend billions to draw water from the sea, a Nobel-winning scientist creates a container-sized machine that extracts up to 1,000 liters per day from dry air and uses ultrasound to release water in minutes, even in the middle of the desert.

Belgium will sink 23 giant concrete caissons, each weighing 22,000 tons, in the North Sea to build the world’s first artificial energy island 45 km off the coast, forming offshore electrical walls.

New microwave that can replace three appliances hits the market: Sharp launches 3-in-1 model that combines air fryer, convection oven, and heating in 0.9 cubic feet for small kitchens

Canadians are disappearing from the United States: The US feels the absence of Canada financially, while hotels, casinos, and tourist destinations try to attract visitors back with promotions.

It seems like science fiction, but it already exists: a Swedish electric boat uses a car battery, carbon fiber hull, and smart hydrofoils to fly over the water and travel 105 km in almost total silence.

Trump’s visit to China could reveal a future that scares workers: dark factories, robots working non-stop, and industrial jobs disappearing before the eyes of the United States.

A public school student single-handedly created a machine capable of treating water for up to 50 people using only solar energy. It was awarded third place at one of the most important science fairs in the world.

BRAM Offshore is hiring for officer, technician, analyst, and manager positions in RJ and Aracaju, offering benefits, CLT employment, a hybrid work model, and the opportunity to work for a company with over 70 specialized vessels in the Brazilian offshore oil and gas maritime sector.

Swiss-led researchers warn that tourism on melting glaciers may be destroying exactly the landscapes that visitors want to see before they disappear, and that geotextile covers and helicopter flights only exacerbate the problem instead of solving it.

Dry cleaning is leaving behind the old chemical smell and showing that clean clothes can also use much less water.

Scientists make worrying discovery: New study reveals that airborne microplastics can worsen global warming on a scale comparable to that of 200 coal power plants spread across the planet.
