Scientists detect molten rock layer hidden under Earth's tectonic plates
Scientists have discovered a new layer of partly molten rock under the Earth's crust that might help settle a long-standing debate about how tectonic plates move.

Late on the Earth night of May 4, or Sol 1222 on Mars, the seismometer aboard NASA's InSight Mars Lander detected a quake on the Red Planet, with reverberations lasting many hours. The marsquake was at least five times as ...

Studies of mid-ocean ridge basalts (MORBs) show a variable Fe isotope composition of the oceanic upper mantle, beyond explanation by processes of mantle melting from a uniform source and magma evolution, indicating Fe isotope ...

What is the structure of the Earth? For starters, it consists of several layers: the crust, the upper and lower mantle, and the core. The mantle makes up most of our planet's volume—84%. The lower mantle represents 55% ...

Just like honey slowly dripping from a spoon, parts of the rocky outermost layer of Earth's shell are continuously sinking into the more fluid layer of the planet's mantle over the course of millions of years. Known as lithospheric ...

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, it behaves as a viscous ...

The planet is shaped by forces deep within its interior. These push the plates of the Earth's crust against each other, causing mountains and volcanoes to form along the collision zones. But when reconstructing what exactly ...

Olivine is an important component of Earth's upper mantle. The effect of boron on the properties of olivine has been previously ignored since boron is largely incompatible with olivine. Most recovered natural olivine samples ...
