The discovery is made in one of the deepest waters.
Basalt is one of the most common igneous rocks that can be found on Earth. The newly discovered type of Basalt found beneath the Pacific ocean formed due to the volcano’s massive and hot eruption. It was never be thought before that the mantle of the Earth consists of more volcanos material and even hotter.
According to researchers, this discovery’s chemical composition and mineralogy are different; the researchers also include that this newly discovered Basalt is highly different from the present known Basalt on Earth and even the moon’s Basalt.
The newly discovered Basalt was formed, laid, and buried under the sea floor’s deep sediments, that the reason it could not be found before. However, this new technology with highly sophisticated tools helps drill deep down to the seafloor and even deeper.
The research team found this new Basalt drilled about 6 kilometers deep on the seafloor in the Amami Sankaku Basin, located nearly 1000 kilometers from the south-west of Fuji Volcano. This research was carried out on the “Ring of Fire“, birthplace famous for volcanic eruptions and earthquakes.
Researchers believe that” There still many discoveries yet to make on Earth.”
It is also considered that this new Basalt is formed from the massive eruption of a volcano, covering the size of western Europe, and about 1 to 2 million years ago happened according to geological time scale.
