At the next EGU2017 (the most important Geological Congress in Europe) we'll present a poster within the Session HS8.2.8 "Innovative methods for the quantification of processes in the sub-surface", dealing with the re-processing of existing AEM data. The data was originally collected, in Sierra Leone, for mineral exploration purposes. Thanks to our advanced procedure, we were able to extract crucial information for the hydrogeologists (above all thickness and distribution of regolith aquifer). These information would have been lost if a pure "exploration" approach had been used for the data processing.
Considering the large amount of AEM data already collected that can be made available, the Governments could adopt similar approach elsewhere, improving significantly the geological and hydrogeological knowledge of wide areas, at present poorly mapped.
