Mineral physics: The spin deep within
Abstract
The Earth's lower mantle, located between the depths of about 660 km to 2,890 km, is a region with a distinct mineralogical composition. The bulk of this region is made up of two mineral phases — silicate perovskite (|[sim]|75%) and magnesiow|[uuml]|stite (|[sim]|20%) — although in the lowermost few hundred kilometres, perovskite transforms into a denser phase termed post-perovskite.
