Turning trash into diamonds: recycling Mother Nature's way

Recently published in Nature’s Scientific Reports, EDRG researchers discovered that diamonds found in oceanic rocks and the so-called super-deep continental diamonds share a common origin of recycled organic carbon deep within the Earth’s mantle.

The Earth’s deepest diamonds are commonly made up of former living organisms that have effectively been recycled more than 400 kilometres below the surface.

The world’s largest plagiogranite formed by reworking of juvenile crust, not in a mid-ocean ridge environment as commonly assumed

Published in Nature journal Communications Earth & Environment, the EDRG team and collaborators report the world’s largest known plagiogranite complex in the Eastern Desert of Egypt. Data indicates that the complex was produced by extensive partial melting of the accreted oceanic lower crust (as a proto-continental crust) instead of the previously known mechanisms in mid-ocean ridge environments.

Traveling Geologist

The work of previous EDRG team member, Chris Spencer, has seen him visit many exotic and remote locations around the world, documented on his travel blog Traveling Geologist. The page has now expanded to provide a platform for other Earth scientists to share their adventures – check out some of the incredible photos and stories.
