Earthquakes are fracturing solid rock nearly 90 kilometers beneath stable continental interiors, a depth where standard ...

The mechanical behaviour of crustal rocks governs a spectrum of geological and engineering phenomena, from fault rupture and seismicity to the stability of underground excavations and geothermal ...

Seismic anisotropy arises when elastic waves travel at different speeds depending on their direction through the Earth’s crust. This directional dependence reflects the internal fabric of crustal ...

Sapphires are among the most precious gems, yet they consist solely of chemically 'contaminated' aluminum oxide, or corundum. It is widely assumed that these crystals with their characteristically ...

Africa’s Turkana Rift Zone, a hotbed of hominin fossils, is caught in the act of “necking," a critical transition toward continental breakup.

Scientists discovered how Earth recycles continents deep underground, shaping the unusual rocks found in ancient mountain ...

Geoscientists have uncovered a missing link in the enigmatic story of how the continents developed- - a revised origin story that doesn't require the start of plate tectonics or any external factor to ...

One of the main achievements in the Earth science is the development of plate tectonics theory in the 20 th century. It successfully explains the generation and extinction of oceanic plate from ...

Scientists find 3.8 billion year old rocks that were part of the Earth's early crust on the Isua Greenstone Belt in Greenland. The area in Greenland, also called the Isua Supracrustal Belt, is an ...

Over 400 million years ago, an upwelling of hot rock from Earth's mantle wrenched apart the crust in Mongolia, creating an ocean that survived for 115 million years. The geological history of this ...
