  • The origin of Archean SCLM -- and its diamonds »

    monocrystalline diamonds and their fibrous/granular coats appear to have grown from the same type(s) of fluid. If most peridotitic diamonds are related to the metasomatic modification of the dunitic Archean SCLM, then progressive metasomatism of the SCLM through time should decrease its overall prospectivity for diamonds.

  • Diamond formation during metasomatism of mantle

    2018-9-14 · A xenolith of bimineralic eclogite from the Udachnaya kimberlite pipe provides a snapshot of interaction between mantle rocks and diamond-forming fluids/melts. The major-element composition of the eclogite is similar to that of N-MORB and/or oceanic gabbros, but its trace-element pattern shows the effects of mantle metasomatism, which resulted in diamond formation. The diamonds …
