Abstract:

This method is presented, using a simplified case of volcanic-associated massive sulphide type deposits as an example. Geological, geochemical, and geophysical criteria are considered on local and regional levels. The local geological criteria are subdivided into: stratigraphy, lithology, alteration and/or mineralization and structure. The concept of geomerit index and a procedure for computing this index are introduced. The method of consistency-driven pairwise comparisons can be combined with other quantitative and qualitative assessment methods, enhancing them by incorporation of non-measurable geological critera and by computation of weights. The consistency-driven approach allows experts to refine at-times subjective judgments concerning exploration and land-use planning, and contributes to the improvement of mineral-potential assessments.
