The handbook will be published over the next few years in a series of individual volumes. In addition ti this book the following volumes are being prepared : Statistics and Data Analysis in Geochemical Prospecting, rock geochemistry in mineral exploration, Drainage Geochemistry in Mineral Exploration, Soil Geochemistry in Mineral Exploration, and Volatile Elements in Mineral Exploration. Each of these volumes will have different authors (or editors in the case of multi-author books), and the approaches to the subject will necessary be different. An attempt has been made to conform to a common set of objectives. These are: (1)The theme of the series is ore-finding; the broad test for inclusion or material is that is should be relevant to the discovery of mineral deposits. (2) The information is presented in sufficient detail and in a form to be immediately understood- and applied by non-specialist practising geologists. (3) Notwithstanding to the "how-to" practical exploration geochemical approach to ore-finding, the dedication of a volume to each of the various aspects of exploration geochemistry allows adequate space for a philosophical examination of geochemical problems and applications and the presentation of the theoretical bases of exploration geochemistry. It is appropriate that the first volume in this series is Analytical Methods in Geochemical Prospecting by W. K. Fletcher. The rapid growth in exploration geochemistry alluded to above apart from the pressure from mining companies for increased exploration capacity is due to two main factors; the development of rapid, cheap multi-element analytical techniques; and the simultaneous development and increasing availability of computer technology that allows the vast increase in analytical data to be handled efficiently.
