Oceanic crust formation is dynamic after all Date: November 29, 2009 Source: Brown University Summary: Earth scientists have found strong evidence that the geological processes that lead to the ...

To do so, Dr. Ziyi Zhu, Research Fellow at Monash University, Australia, and colleagues developed a theoretical model for the mass/volume balance of continental crust and compared the amount of ...

Far beneath the ocean's surface, where mountain belts rise and ancient oceanic crust lies hidden, a long-lost tectonic plate ...

Geologists knew that some of Earth's crust regularly sinks back into the mantle, but until now, they weren't sure how much gets recycled -- a key to understanding the history of crustal formation ...

Oceanic islands preferred thin crust. ... Sciences, has been involved in a world-wide collaboration which sheds new light on the processes behind the formation of island chains.

Their formation requires iron- and silicon-rich fluids, ... As the Archaean eon progressed, the oceanic crust produced was rich in Al12. When Al-rich crust undergoes hydrothermal alteration, ...

The early Earth was a very different place. Go back 4 billion years and the Earth's surface was mostly basalt -- the stuff of oceanic crust. After the formation of the planet (and the subsequent ...

To better understand crust formation, Dygert and a team of researchers analyzed ancient oceanic rocks -- rocks that are now exposed on dry land. The 100-million-year-old rocks were found in a ...

Most oceanic crust is less than 200 million years old, because it is typically recycled back into the Earth's mantle at subduction zones (where two tectonic plates collide).But a new study shows ...

Earth scientists at Brown University have found strong evidence that the geological processes that lead to the formation of oceanic crust are not as uniformly passive as believed. The team found ...
