2017-9-29 enhancement methods for the detection. We find that the vegetation anomalies, defined by the large ratios, correspond well to the high potential zones of ore deposits and known major deposits. Consequently, our methods can extend the applicability of remote sensing-based mineral exploration to the areas covered by

2011-10-2 Mineral exploration is the second stage of the key exploration activities to locate surface mineralization and any old workings in a smaller area of identified geological, geochemical, and geophysical anomalies. It is therefore the follow-up of geological, geochemical, and geophysical anomalies from a reconnaissance survey.
