Schematic representation of the process of subduction of tectonic plates and of a mantle plume rising from an LLSVP. Schematic representation of the process of subduction of tectonic plates and of ...

Nobody knew what they are, and whether they are only a temporary phenomenon, or if they have been sitting there for millions ...

"The Earth's mantle is the engine that drives all these phenomena. Take, for example, mantle plumes, which are large bubbles of hot material that rise from the Earth's deep interior as in a lava ...

Over 25 years ago, researchers discovered that some of these deep Earth reverberations pointed to the existence of two underground “super-continents” hundreds of miles beneath Africa and the Pacific ...

July 11, 2022 — By analyzing noble gas isotope data, a scientist determined that the ancient plume mantle (the deep part) had a water concentration that was a factor of 4 to 250 times lower when ...

Take, for example, mantle plumes, which are large bubbles of hot material that rise from the Earth’s deep interior as in a lava lamp.” Once they finally reach the surface, they cause vulcanism ...

Here’s how it works. 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 ...
