By simulating the movement of two continent-sized Big Lower-Mantle Basal Structures, or BLOBs, researchers may have uncovered ...

Geochemists suggest that Earth's upper mantle varies in composition over kilometer-sized pockets. New research by Brown University geochemists provides new insights on the scale at which Earth's ...

The Earth's mantle constitutes over 80% of the planet's volume and is a key reservoir in global geochemical cycling. An overview of the progress in understanding the generation of mid-ocean-ridge ...

Home / Measuring The New Composition Of Earth’s Mantle. Posted in Press Release Measuring The New Composition Of Earth’s Mantle by SpaceRef September 17, 2019 July 15, 2024.

Current understanding is that the chemical composition of the Earth's mantle is relatively homogeneous. But experiments now show that this view is too simplistic. Their results solve a key problem ...

Geochemists measure new composition of Earth's mantle Researchers suspect greater dynamics than previously assumed between the Earth's surface and its mantle / Study published in "Nature Geoscience" ...

Mantle plumes were the implicit link in previous studies relating BLOBS to giant volcanic eruptions. Their shape is a bit ...

Scientists still disagree about the composition of the deep mantle. There are odd structures near the core-mantle boundary called large low-shear velocity provinces (LLVPs), where seismic waves ...

A plume of molten rock deep beneath eastern Africa is pulsing upward in rhythmic surges, slowly splitting the continent and ...

Mars’ mantle is divided into a partially molten outer layer and a fully molten, silicon-rich layer that lies closer to the planet’s core. This discovery was made by two independent teams and ...
