Notice: Dr Tania R Marshall has been appointed as Chair of the SAMCODE Standards Committee (SSC). The SSC is the body tasked to develop, maintain, administer and promote the South African Mineral Codes collectively known as SAMCODE

11th International Kimberlite Conference, Gaborone, Botswana, 18-22 September, 2017 www.11ikc.com

International Kimberlite Conferences are special events which take place about every four years. Generous sponsorship has been a key to the success of these conferences. The organisers would welcome any expression of interest in sponsoring of the 11th International Kimberlite Conference via the 11 IKC Secretariat ([email protected]).

THESES QUERY: In the past few years, I have requested from the individuals on the distribution list for awareness and access to theses. These are critical and great resources for all of us.Please send me the reference to any thesis and if permissible a pdf copy for distribution/ or an email for the author to access and request a copy ( at user’s expense). I do not believe there is a functioning arena for listing outside of individual universities. Stachel has been very supportive. Gurney has promised that he will send me a listing of UCT ones in the coming year (2016). I would welcome other universities to provide such to allow me to place the reference in this service. Please (if possible) provide the author, title, number of pages, university, and a brief note as to a specific area, deposit or technology ** if it is not in the title!!!
