New insights into the formation of Earth’s crust

New research from Mauricio Ibanez-Mejia, an assistant professor of Earth and environmental sciences at the University of Rochester, gives scientists better insight into the...

Study explores the density of the tectonic plates and why they...

A fast collision rate between tectonic plates and a young age (millions of years) are two factors that favour the sinking of the lithosphere...

The Antarctic: Data about the structure of the icy continent

The Antarctic is one of the parts of earth that we know the least about. Due to the massive ice shield, the collection of...

Study points to one cause for several mysteries linked to breathable...

Earth's breathable atmosphere is key for life, and a new study suggests that the first burst of oxygen was added by a spate of...

Extra-terrestrial impacts may have triggered ‘bursts’ of plate tectonics

When -- and how -- Earth's surface evolved from a hot, primordial mush into a rocky planet continually resurfaced by plate tectonics remain some...

New geologic modeling method explains collapse of ancient mountains in American...

By using the latest computer numerical modeling technologies, combined with geologic compilations and seismic data, researchers in the Department of Geosciences at Stony Brook...

Telescopes and satellites combine to map entire planet’s ground movement

Curtin University research has revealed how pairing satellite images with an existing global network of radio telescopes can be used to paint a previously...

What makes the Earth’s surface move?

Do tectonic plates move because of motion in the Earth's mantle, or is the mantle driven by the movement of the plates? Or could...

Collision course: A geological mystery in the Himalayas

According to Craig Martin, deciphering Earth's geologic past is like an ant climbing over a car crash. "You've got to work out how the...

Study provides new insight into the origin of Las Cañadas caldera...

Las Cañadas caldera (Tenerife, Canary Islands) is the result of different episodes of caldera collapses, associated to large explosive eruptions that triggered several landslides...

Unusual fault rupture during Kaikōura quake

One of the 24-plus faults that ruptured in the 2016 magnitude 7.8 Kaikōura earthquake has turned out to be even more unusual than scientists...

Why are mountains so high?

Over millions of years, Earth's summits and valleys have moved and shifted, resulting in the dramatic landscapes of peaks and shadows we know today....

Machu Picchu: Ancient Incan sanctuary intentionally built on faults

The ancient Incan sanctuary of Machu Picchu is considered one of humanity's greatest architectural achievements. Built in a remote Andean setting atop a narrow...

Ancient volcanoes reveal Earth’s recycled crust

Ancient volcanoes dating back billions of years could provide new insights into how the Earth's surface is recycled, according to scientists at the University...

What drives plate tectonics?

Plate tectonics was founded in the late 1960s, and it concerns the distribution and movements of plates, the uppermost layer of the Earth. Plate...

Researchers uncover 2.5 billion years of Earth’s continents breaking up and...

A new study of rocks that formed billions of years ago lends fresh insight into how Earth's plate tectonics, or the movement of large...

Scientists discover how and when a subterranean ocean emerged

"The mechanism which caused the crust that had been altered by seawater to sink into the mantle functioned over 3.3 billion years ago. This...

Curved slickenlines preserve the direction of rupture propagation

Slip-parallel grooves (striations) on fault surfaces are considered a robust indicator of fault slip direction, yet their potential for recording aspects of earthquake rupture...

New model suggests lost continents for early Earth

A new radioactivity model of Earth's ancient rocks calls into question current models for the formation of Earth's continental crust, suggesting continents may have...

Earthquake swarms reveal missing piece of tectonic plate-volcano puzzle

Deep under the ocean bed, a sinking tectonic plate causes a "swarm" of earthquakes, feeding molten rock into newly forming volcanoes, new research has...
