Oceanic crust breakthrough: Solving a magma mystery

This item was filled under Climate
Oceanic crust covers two-thirds of Earth's solid surface, but scientists still don't entirely understand the process by which it is made. Analysis of more than 600 samples of oceanic crust reveals a systemic pattern that alters long-held beliefs about how this process works, explaining a crucial step in understanding Earth's geological deep processes....
