The Geo-Platinum 87 Symposium, held at the Open University during April 1987, was designed as a forum for presentation of new research results on the occurrence, genesis, geochemistry, mineralogy and analysis of the platinum-group elements (PGE). With the support of the Open University and the Mineral Industry Research Organisation, the symposium was attended by 115 representatives of university departments, research institutions and members of the mining and mineral exploration industries. An introduction to the symposium was provided by two invited papers from C. J. Morrissey (Riofinex North) and C. R. N. Clark (Johnson Matthey) which were designed to give perspective to the goals of PGE research work. The first of these papers gave a provocative insight into the aims and objectives of an exploration manager, examining the influence of supply, demand and perceived world reserves on exploration strategy. The second invited paper gave a valuable view of the industrial uses, market trends and predicted changes in the commercial value of the platinum-group elements from the standpoint of a refining company and supplier. These invited papers are reproduced in this volume and are followed by twenty­ four full papers and twenty abstracts that reflect the wide range of research topics presented at the symposium.
