Scientists offer new insights into origin of diamonds in group of meteorites

Scientists have offered new insights into the origin of diamonds in a group of stony meteorites called ureilites. These diamonds most likely formed by rapid shock transformation from graphite during one or more major impacts into the ureilite parent asteroid in the early solar system. Previously, researchers have proposed that diamonds in ureilites formed like those on Earth -- deep in the mantle of the planet, where the high pressures needed to form a diamond, are created by the weight of the overlying rock.
