GOLD ENVIRONMENTS AND FAVOURABILITYGEOLOGY AND ORE 9 / 2007PerspectivesThe statistical approach has a potential ofidentifying and mapping other types ofmineral occurrences as well as specific tectonicunits in poorly known areas and canbe used on local or regional scale, dependingon the resolution of the involved datasets.The statistical approach has been usedto examine gold showings in a moderatelyexplored region.The approach could also be applied toeconomic deposits from well-known historicor active mining camps. As shown inthe case in the Nuuk area, the statisticalapproach should always be used in combinationwith other geological approaches.The results of a statistical analysis shouldbe cross-validated and critically balancedaccording to geological knowledge.Concluding remarksThe detailed investigations of primary geologicalenvironments of supracrustal rocksin the Nuuk region have revealed a greatdiversity in environments, which all carrygold. The results from the statistical analysishave been positive in the sense thatareas with high favourability for new goldoccurrences have been outlined.Hydrothermal alteration with epidotization,south of Ameralik fjord.10
