Fragments of continents hidden under lava in the Indian Ocean

The islands Reunion and Mauritius, both well-known tourist destinations, are hiding a micro-continent, which has now been discovered. The continent fragment known as Mauritia detached about 60 million years ago while Madagascar ...

Deep recycling in the Earth faster than thought

The recycling of the Earth's crust in volcanoes happens much faster than scientists have previously assumed. Rock of the oceanic crust, which sinks deep into the earth due to the movement of tectonic plates, reemerges through ...

Exploring water in the deep Earth

(PhysOrg.com) -- Research published today in Nature Geoscience provides new insight into the water cycle of the deep Earth, volcanic activity in the Pacific and the potential catastrophic effects when these two combine.

Hot spot at Hawaii? Not so fast

Through analysis of volcanic tracks, Rice University geophysicists have concluded that hot spots like those that formed the Hawaiian Islands aren't moving as fast as recently thought.

Catching mantle plumes by their magma tails

Hawaii's volcanos stand as silent sentinels. They guard the secret of how they formed, thousands of miles away from where the edges of tectonic plates clash and generate magma for most volcanos. A 2017 Nature study by Jones ...

Study challenges widely accepted theory of Yellowstone formation

Understanding the complex geological processes that form supervolcanoes could ultimately help geologists determine what triggers their eruptions. A new study using an advanced computer model casts doubt on previously held ...
