A section of the upper mantle and crust under the Sierra Nevada mountains is peeling away, in a process that may mimic how ...

Using nearly four decades of seismic data from stations encompassing the northern, central, and southern Sierra Nevada along California's eastern border, geologists have uncovered signs of a critical ...

The phenomenon has been happening for millions of years quietly beneath our feet and could shed new light on how the ...

The processes that form continental crust from the denser basaltic rocks of the upper mantle may make the lower lithosphere ...

Scientists discovered a hidden process where Earth's crust peels away and sinks, reshaping continents over millions of years, revealing Earth's slow evolution.

Scientists have discovered evidence that California is actually peeling apart below the surface, as dense rocks under the ...

Some can be nearly as old as the solar system itself, about 4.6 billion years. Continental crust is generally higher in silica, which makes it less dense. This low density makes continents too ...

For geologists, a continent is a large area of thick continental crust composed of granite or similar igneous rocks, forming the continental base, in combination with metamorphic rocks ...
