'Dark Magma' Could Explain Mystery Volcanoes

sciencehabit writes: The magma fueling the volcanoes of Hawaii and Yellowstone National Park pipes up from deep inside the planet. Scientists have struggled to understand why there are hot spots there, so far from the grinding tectonic plate boundaries at which volcanoes normally appear. New research chalks the mystery up to 'dark magma': deep underground pockets of red-hot molten rock that siphon energy from Earth's core. If the team is right, its work could illuminate a key part of Earth's geology. These plumes are one of the most important things to understand because the movement of heat powers many processes on the planet. For one, Earth's magnetic field depends on how the core spins and flows inside the planet. As a result, the way heat flows from the core to the mantle could potentially affect the way Earth's magnetic field evolves over time.

Dont you think the term "Dark ???" is being overused now?
Hey! theres something we dont know what it is.. lets call it "Dark... Meatcake!"

New Madrid Seismic Zone

I wonder if they can apply this to why New Madrid Missouri had one of the biggest recorded earthquakes in US history while not being very near any fault line.
