ABSTRACT: Future research in exploration geochemistry should focus on developing and further documenting unconventional methods for the detection of concealed mineral deposits. Geochemical attributes that can be recognized beyond the obvious limits of the deposits may be considered farfield features of ore deposits. They can be primary, if formed during mineralization, or secondary, if formed after the mineralizing process, as a result of weathering. Research should focus on understanding the formation, consistency, and the scale of far-field features. Three specific avenues of research are suggested: (a) determining a genetic link between primary far-field features and ore deposits, (b) understanding the processes that lead to secondary far-field features, and (c) documenting the scale and footprint of primary and secondary features. Incorporation of methods for detecting far-field features into field-based exploration programs may increase the probability of success, especially in covered terrains.
