The mantle of the Earth, up to 1,800 miles (2,900 kms) thick and 84% of the Earth's volume, was assumed to be a simple ...

Scientists have known since the 1960s that mantle plumes stay in place for a very long time while the Earth's plates move over them. Every time the plate shifts a bit, the mantle plume produces a ...

Indian scientists have uncovered the possible cause behind the Indian Ocean Geoid Low (IOGL), the lowest geoid anomaly on ...

This is a 3D view of the top 1,000 kilometers of the earth's mantle beneath the central Pacific showing the relationship between seismically-slow "plumes" and channels imaged in the study.

Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

These plumes stretch from the very bottom of the mantle to volcanic hotspots at the surface, such as the Hawaiian islands. What's inside Earth quiz : Test your knowledge of our planet's hidden ...

Continent-size islands deep inside Earth's mantle could be more than a billion years old, a new study finds. Known as large low-seismic-velocity provinces (LLSVPs), these blobs are both hotter and ...

Conducted by researchers from Ocean University of China and Tohoku University, Japan, the work combines innovative seismic methodologies to map mantle flow patterns, slab-plume interactions ...

Using the adjusted GIA model, they reduced the viscosity to the upper mantle rocks along the path of the plume across Greenland. The new model simulations showed that the rate of ground uplift was ...
