‘Dark magma’ could explain mystery volcanoes

Scientists Confirm Existence of Largest Single Volcano On Earth

Basalt, the most-common rock on Earth’s surface, encases green crystals--a geologic "nesting doll" phenomenon called a xenolith. Basalts such as this one derive from a section of the mantle that has been depleted in incompatible trace elements, which is usually attributed to continental crust formation. In their work, Tucker and his collaborators propose another mechanism that would impart this signature. Credit: Carnegie Institution for Science

This model shows how iron- and magnesium-rich magma (green) is formed at great depth and can move along the outer edges of the large Altiplano-Puna magma body (APMB)(red) to gradually force its way up to the surface during a volcanic eruption. Eruptions with such lava are uncommon and provide a unique insight into the processes that take place deep inside the Earth under the Andes. Credit: Osvaldo Gonzalez Maurel
