As continents continue moving, study suggests effects on biodiversity

Continental drift and plate tectonics—the notion that large chunks of Earth's crust slowly but inexorably shift positions—was proposed in 1912 but not accepted until...

Stirring things up in the Earth’s mantle

New insights into the convection patterns of the Earth's mantle and its chemical makeup have been revealed by a researcher from the University of...

Changes in tectonic activity may have shaped composition of Panama Canal...

Changes in the composition of magma may have caused variations in the Panama Canal volcanic rock formations, according to a study published May 10,...

New timeline proposed for plate tectonics

Earth's history should include 'pre-plate tectonic' and 'plate tectonic' phases beginning less than a billion years ago, according to a team of geoscientists in...

Continental crust thanks to the right mixture

For the first time, ETH scientists have successfully recreated the formation of continental crust in the Archean using a computer simulation. The model helps...

What Earth was like 4.4 billion years ago?

Scientists at The Australian National University (ANU) say the early Earth was likely to be barren, flat and almost entirely under water with a...

New theory on how Earth’s crust was created

More than 90% of Earth's continental crust is made up of silica-rich minerals, such as feldspar and quartz. But where did this silica-enriched material...

A new interpretation of petrogenesis of Earth’s early continental crust

The Earth's continental crust was mainly formed in the Archean period, ~2.5 to 4.0 billion years ago, and is chiefly composed of tonalite, trondhjemite...

Early organic carbon got deep burial in mantle

Rice University petrologists who recreated hot, high-pressure conditions from 60 miles below Earth's surface have found a new clue about a crucial event in...

Scientific drilling at Wadi Manasah to throw light on oceanic plates

The latest scientific drilling by the Oman Drilling Project at Wadi Manasah in the Wilayat of Bidbid has ended the season with a collection...
