Abstract
Aeroradiometric data set of Isanlu sheet 225 (1:100,000) has been acquired with a view to analyze and interpret for the delineation of hydrothermally altered zones that favour gold mineralization. The acquired aero-radiometric data was subjected to filtering algorithm and enhancement techniques such as shaded relief enhancement, elemental ratio enhancement using Geosoft Oasis Montaj Software. Moreover, Golden Software Surfer was used to identify and present the revealed hydrothermally altered zones. The interpretation of the aero data set has enhanced the delineation of eight hydrothermally altered zones. Therefore, the areas that are hydrothermally altered are ...
