Craton roots diamonds

摘要

This 35th IGC tour offers visitors the opportunity to visit a unique collection of mantle rocks brought to the surface in kimberlites, that have allowed researchers to piece together the nearly four billion year history of the Earth's continents. Complementing the museum-style exhibit Messengers from the Mantle: Craton Roots and Diamonds on display at the Congress, the tour will allow participants to visit the world-famous Mantle Room research collection at the University of Cape Town, which is a most extensive collection of deep Earth samples from southern Africa. It contains over 14,000 mantle and deep crustal xenolith specimens from more than a hundred kimberlites from southern Africa and across the globe.
