A study published in Astronomy & Astrophysics has identified four previously unknown primordial open cluster (OC) groups in the Milky Way. Open clusters, loose assemblies of stars born from the same giant molecular cloud (GMC), are typically...
Forests in the Peruvian Amazon aren't growing back after gold mining—not just because the soil is damaged by toxic metals, but because the land has been depleted of its water. A common mining method known as...

Sink or swim: The fate of sinking tectonic plates depends on their ancient tectonic histories

Newly published research has revealed that compositional rock anomalies within oceanic plates caused by ancient tectonics influence the trajectory and speed of the plates...

New technique allows researchers to look deep within tectonic plates

Caltech researchers have developed a new method to study Earth's structure deep beneath the surface, at the boundary between Earth's brittle crust and the...

New step in tectonic squeeze that turns seafloor into mountains

Scientists use tiny minerals called zircons as geologic timekeepers. Often no bigger than a grain of sand, these crystals record chemical signatures of the...

Plate tectonic surprise: Geologist unexpectedly finds remnants of a lost mega-plate

Utrecht University geologist Suzanna van de Lagemaat has reconstructed a massive and previously unknown tectonic plate that was once one-quarter the size of the...

Plate tectonic surprise: Geologist unexpectedly finds remnants of a lost mega-plate

Utrecht University geologist Suzanna van de Lagemaat has reconstructed a massive and previously unknown tectonic plate that was once one-quarter the size of the...

Earth’s crust, tectonic plates gradually formed, geoscientists find

The Earth's crust continued a slow process of reworking for billions of years, rather than rapidly slowing its growth some 3 billion years ago,...

Scientists investigate tectonic plate boundary earthquake behavior

Renaissance polymath Leonardo da Vinci demonstrated frictional forces slow down the motion of surfaces in contact. Friction, he determined, is proportional to normal force....

New insight into the relationship between slow slip events and the build-up and release of tectonic strain

The Japanese archipelago is actively undergoing seismic shifts due to interactions between the oceanic plate and the continental plate. At the plate boundaries located...

New tectonic plate model could improve earthquake risk assessment

New Zealand is no stranger to earthquakes. Scientists estimate that more than 20,000 occur each year, and the deadliest ones can shudder the entire...

The link between temperature, dehydration and tectonic tremors in Alaska

A Kobe University research group has shed light on how low-frequency tectonic tremors occur; these findings will contribute towards better predictions of future megathrust...

As tectonic plates pull apart, what drives the formation of rifts?

At the boundaries between tectonic plates, narrow rifts can form as Earth’s crust slowly pulls apart. But how, exactly, does this rifting happen? Does pressure from...
