A study reveals that the oldest continental crust on Earth is slowly being broken up by shifting tectonic forces.
Researchers have discovered an unusual plume of magma beneath Oman that may have changed the course of the Indian tectonic plate between 25 million and 40 million years ago.
Regions with thick oceanic crust show little to no seismicity at intermediate depths, whereas adjacent regions with normal oceanic crust (similar to 6-8 km thick) have significant seismicity at ...
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 ...
The Davis Strait never fully evolved into a region where new oceanic crust is formed, as tectonic plates move apart and magma rises to create new ocean floor, the paper outlines.
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 ...
The oldest oceanic crust is ~340 million years old. The oldest continental crust is 4.4 billion years old. Fast and Slow Spreading Ocean Crust The thickness of the crust created at ocean spreading ...
Where does the crust come from? The building blocks of new continental crust come from the depths of the Earth at what are known as continental arc volcanoes, which are found at subduction zones where ...
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 ...
