The mantle is split up into two domains — the African and the Pacific — that emerged when supercontinent Pangaea broke apart. When you purchase through links on our site, we may earn an ...
Had the team found evidence that the mantle plume under Easter Island has been active for 165 million years? To answer that question, Rojas-Agramonte needed evidence from the geology of the 'Ring ...
Scientists have calculated the Earth to be 4.54 billion years old, with an uncertainty of 50 million years on either side.
Geology textbooks describe the Earth's mantle beneath its plates as a well-mixed viscous rock that moves along with those plates like a conveyor belt. But that idea, first set out some 100 years ...
An unexpected find in tiny crystals hints that the Earth's mantle may not quite behave as has been believed for nearly a century.
On present-day Earth, plate subduction continuously modifies the chemical composition of the convecting mantle, and various mantle sources linked to these processes have been widely studied.
As well as offering new insights into mantle composition, the drill core gives us other glimpses into Earth's deep geology and the conditions that could have been involved in the origins of life.
Emerging evidence suggests that plate tectonics, or the recycling of Earth's crust, may have begun much earlier than previously thought — and may be a big reason that our planet harbors life.
Traditionally, textbooks have described the mantle as a viscous, well-mixed layer that shifts along with tectonic plates, much like a conveyor belt. This theory has been a cornerstone of geology for ...
“This study provides a first present-day example of how a cold downwelling from above is breaking up a deep mantle blob,” says Sanne Cottaar, a professor of global seismology at the University ...
Hattori's research on a broad range of geoscience topics includes volcanology, sedimentary geochemistry, and mantle petrology ...
