A new type of rock created during large and exceptionally hot volcanic eruptions has been discovered beneath the Pacific Ocean.
An international team of researchers including the University of Leeds unearthed the previously unknown form of basalt after drilling through the Pacific ocean floor.
The discovery suggests that ocean floor eruptions sourced in the Earth’s mantle were even hotter and more voluminous than previously thought. Report co-author is Dr Ivan Savov, of Leeds’ Institute of Geophysics and Tectonics, in the university’s School of Earth and Environment.
