Geochemical mapping has been undertaken in many parts of the world and at various scales as part of mineral exploration programs over the last 60 years. The designers of geochemical mapping programs are faced with a wide, and growing, variety of sampling, analytical and data processing options. Optimising the options has been largely based on orientation studies but a more systematic approach based on evolving understanding of regolith-landscape evolution and geochemical processes is required to detect deposits with subtle surface expression. In essence we need to address the question “What influence is the mineralogical needle likely to have on the regional regolith haystack?”.

David Cohen is Head of the School of BEES at UNSW and has over 25 years in exploration geochemical research. He is a past president of the Association of Applied Geochemists and co-authored the chapter on Exploration Geochemistry in the recently published Elsevier Treatise on Geochemistry devoted to the Geochemistry of Mineral Deposits. He has wielded everything from chainsaws to portable XRFs in the process.
