A peer-reviewed study published in Science argues that Yellowstone’s volcanic system owes its heat and magma not to a deep ...

An illustration depicting the formation of TTGs in a two-stage mantle plume-sagduction model. Geologists from The University of Hong Kong (HKU) have made a breakthrough in understanding how the ...

For decades, Yellowstone has been held up as one of the clearest examples of a volcanic system fed by an immense column of hot rock rising from deep within the Earth. That picture has shaped ...

According to this interpretation, mantle plumes cause partial melting beneath moving tectonic plates, producing volcanic chains such as the Hawaiian–Emperor chain. However, this hypothesis can't ...

Mars has a reputation as a cold, dead world, but a new study suggests that may be only partially accurate. Researchers from the University of Arizona have analyzed a region that appears to be ...

On Earth, shifting tectonic plates reshuffle the planet's surface and make for a dynamic interior, so the absence of such processes on Mars led many to think of it as a dead planet, where not much ...

Some 75% of the world's volcanoes live along the aptly name Ring of Fire. This makes sense. Hugging a boundary between tectonic pates, the Ring of Fire is an open seam on the planet's interior. But ...

The Mars InSight lander included the first seismograph placed on the red planet, and it has picked up everything from marsquakes to impacts and provided lots of new information on Mars’ interior. But ...

Earth’s mantle is the thick layer of silicate rock between Earth’s crust and its molten core, making up about 84% of our planet’s volume. The mantle is predominantly solid but, on geologic time scales ...

Artist's impression of an active mantle plume – a large blob of warm and buoyant rock – rising from deep inside Mars and pushing up Elysium Planitia, a plain within the planet's northern lowlands.
