We thank Graham Hutchinson for his tireless assistance during SEM and EPMA analysis at the University of Melbourne. We are grateful to Phillip Janney for facilitating access to the John J. Gurney Upper Mantle Room Collection (University of Cape Town), from which samples of the De Beers dyke were loaned. In addition, we thank the De Beers Group and Petra Diamonds for provision of additional samples and for allowing access to the Wesselton mine and Benfontein Farm for sample collection. Jock Robey organised access to various sites in the Kimberley area and supervised sample collection, for which we are exceptionally appreciative. We also thank Stephen Sparks for supplying samples of the Wesselton water tunnel sills. AS thanks Angus Fitzpayne, Hayden Dalton, Madeline Tovey, Lynton Jaques, Simon Shee, and Bruce Wyatt for fruitful discussions on kimberlite emplacement.
