Geologists from the University of Hong Kong (HKU) have made a breakthrough in understanding how Earth's early continents ...

A study reveals that the oldest continental crust on Earth is slowly being broken up by shifting tectonic forces.

The occurrence of intermediate depth seismicity (70-300 km) is commonly attributed to the dehydration of hydrous phases within the downgoing oceanic plate. While some water is incorporated into the ...

Deep beneath Earth’s surface, researchers have discovered an ancient seafloor buried for millions of years. This unexpected ...

Giant creatures evolve beneath the ocean's surface. Their discovery changes our perception of underwater life. At depths of over 8,200 feet (2,500 meters), scientists have uncovered a universe teeming ...

At its thinnest, Earth's crust is 6 kilometers (3.7 miles) thick. We do have the tools to drill down pretty deep from the continental surface – as evidenced by the mind-blowing 12,262-metre deep Kola ...

Oceanic crust is closer to 4-6 miles (7-10 kilometers) thick and made of denser rock like basalt. This means that when these two types of plates collide as they move on the planet's surface, oceanic ...

Geophysical characteristics of the ultraslow spreading Gakkel Ridge, Arctic Ocean The crustal thickness along the Gakkel Ridge varies greatly. Beneath some of the centers of focused magmatism, the ...

Research published in the journal Science has provided new insights into the composition of the Earth’s crust and what makes it uniquely habitable. The study, conducted by a team of scientists at the ...

Oceanic crust that underlies the oceans is thin, dense and low in silica (silicon oxide) while continental crust is thick, buoyant and silica rich. This creates a planet where much of the land surface ...
