Researchers offer glimpse into dinosaur ecosystems

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

A new tool to predict volcanic eruptions

The inner core is likely composed of the hexagonal close packed phase of iron and located at the center of the Earth at pressures between 329 and 364 GPa and temperatures of ~5000 to ~6000 K. Credit: Ehime University

Is the Earth’s inner core oscillating and translating anomalously?

The early Earth was hotter than it is today and this affected the strength of the crust and mantle.
