New research from HKU geologists suggests that Earth's first continents were born not from plate tectonics, but from deep ...

These transformations influence tectonic plate dynamics and mantle convection. The discovery of an unusually thick transition zone beneath the Lesser Antilles suggests a unique, basalt-rich ...

Although the plate is a relatively new tectonic unit, it combines materials that have formed over a long period of geologic time. These rocks comprise a 45-km-thick layer of continental crust. Because ...

Due to the radiative thermal conductivity of the mineral olivine, only oceanic plates over 60 million years old and ...

Chemical fingerprints from volcanic rock offer hints of what’s happening in the mantle below the area where three rift zones ...

The vertical movement of the mantle is one of the driving forces that brings about large-scale geological changes to the ...
