Young peridotitic diamonds from the Mir kimberlite pipe


MINERAL inclusions in diamonds contained in the explosive volcanic rocks known as kimberlites provide an important record of geochemical processes in the continental lithosphere. Samarium–neodymium model ages as old as 3.2 Gyr have been obtained for many peridotitic mineral inclusions1–4, pointing to the great antiquity of the host 'peridotitic' diamonds… (More)
