Study Reveals Earth's Mantle Secrets Impacting Habitability

Summary

Story summary

Rutgers University researchers identify large low-shear-velocity provinces (LLSVPs) and ultra-low-velocity zones (ULVZs) at the mantle-core boundary as features informing Earth's formation and habitability.
The study suggests silicon and magnesium from the core have leaked into the mantle over billions of years, disrupting chemical layering.
Published in Nature Geoscience, the findings suggest these Earth features could influence volcanic activity and atmospheric evolution, helping explain habitability relative to Venus and Mars.
