The emotions of youth become less all-important and less demanding of our attention. Young people feel that every perceived slight needs ...

Oceanic crust has been made almost continuously for ... the youngest was 13.5 million years old and the oldest 104 million years old. During next decade, Suzuki and his team painstakingly studied ...

The continent portion of tectonic plates remains at the surface and the oceanic part of tectonic plates is recycled into the planet. As a result, the oldest continental crust is 4 billion years old, ...

One of the key indicators has been whether or not fragments of oceanic crust, generated at sea-floor spreading centers, are preserved in the planet's oldest crust. New research integrating what has ...

The oldest Archaean crater before this discovery ... of erosion and subduction in recycling primary (basaltic, oceanic) crust back into the convecting mantle,” Kirkland and Johnson said in ...

The oldest Archaean crater before this discovery went back only ... reflecting the destructive efficiency of erosion and subduction in recycling primary (basaltic, oceanic) crust back into the ...

The oldest oceanic plates on Earth date back about 200 million years. In contrast, the crust of continents lies under shallow oceans and land. It is highly variable in composition and age.

In a geologic balancing act, dense oceanic crust is destroyed at subduction zones, where one plate slides under another. The oldest known bit of oceanic crust, located in the Mediterranean ...

But new research suggests that even the oldest crust is disintegrating due to natural ... by this special form of subduction occurring near oceanic plates, revealing how the continents evolved ...
