The Vredefort crater is well known in the geological literature, because it is situated in the Witwatersrand Group, the repository of almost half of the world’s gold reserves, and was generated by an explosion process. One of the key problems in the history of the crater is the timing of formation of cordierite–orthopyroxene reaction structures, which develop extensively around relict garnet in the metapelites of the granulite core of the impact structure. In the middle 1970s, W. Schreyer and K… Expand
