Formation of the Alps: Detaching and uplifting, not bulldozing

For a long time, geoscientists have assumed that the Alps were formed when the Adriatic plate from the south collided with the Eurasian plate...

Scientists decipher the role of carbon and the break-up of continents

University of New Mexico (UNM) Professor of Earth and Planetary Sciences, Dr. Tobias Fischer and Syracuse University research fellow (now University of Auckland Lecturer),...

New clues to deep earthquake mystery

A new understanding of our planet's deepest earthquakes could help unravel one of the most mysterious geophysical processes on Earth. Deep earthquakes -- those at...

Earth’s evolutionary tale, researchers probe materials at deep-Earth conditions

Far below the Earth's surface, about 1,800 miles deep, lies a roiling magmatic region sandwiched between the solid silicate-based mantle and molten iron-rich core:...

The Great Unconformity : A billion years is missing from the...

The geologic record is exactly that: a record. The strata of rock tell scientists about past environments, much like pages in an encyclopedia. Except...

Geologists determine early Earth was a ‘water world’ by studying exposed...

The Earth of 3.2 billion years ago was a "water world" of submerged continents, geologists say after analyzing oxygen isotope data from ancient ocean...

New pieces of evidence found in the Alborán Sea possibly related...

Under the waters of the eastern Alborán Sea and buried at the shadow of an old volcanic edifice lies a body of sediments that...

Hidden past of Earth’s oldest continents unearthed

New international research led by the University of St Andrews presents a novel way to understand the structure and formation of our oldest continents. The...

Lithospheric thickening beneath the Betics and Rif mountains pulls down the...

A new study made by researchers at the Institute of Earth Sciences Jaume Almera of the Spanish National Research Council (ICTJA-CSIC) has been able...

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...

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...

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...
