Phys.org / Mars' 'young' volcanoes prove more complex than scientists once thought

What appears to be a single volcanic eruption is often the result of complex processes operating deep beneath the surface, where magma moves, evolves, and changes over long periods of time. To fully understand how volcanoes ...
