This work uses part of an airborne survey data of Adola belt generated by GeologicalrnSurvey of Ethiopia in 1994. The belt has been studied by different researchers to explain the structuralrnpattern and mineralization. Here, the different enhancing filters are applied on the aeromagnetic andrngamma ray spectroscopic data and the geophysical signatures gleaned are used to explain the rock unitsrnand structural features associated to mineralization. In addition, the airborne coverage data of Ethiopiarnis updated with new coverage data gathered for petroleum exploration.rnThe Upward Continuation (UWC) filter at different height shows the effects of deeper regionalrnsource by removing the shallower effects and possible noises. Upward continued TMI (up to 500m)rnabove the flight height of the magnetometer showed a WNW-ESE trending linear structure at thernsouthern parts of the area. Further enhancement using tilt derivative reveals some more geologicalrnfeatures.rnThe Gamma ray spectrometric data is regridded with a cell size of 15m and a bi directional linerngridding is applied using Oasis Montaj, and filtered and shaded maps of the individual radio elementsrn(U, TH, K, and TC) and a ternary image are produced. The ternary map demarcated major geologicalrnunits such as basalts, gneisses and central volcano sedimentary terrain. These are peculiar signaturesrnwell marked at the eastern, western and central part of the area. The ratio map of Th/K is prepared tornselect the alteration zones favourable for mineralization. The Total Count map mapped the centralrnvolcano sedimentary belt with a low total count from northern end up to the southern covering a widernpart of the study area. It also portrayed area around Kilenso Babicho, Meleka and north Sakaro with arnhigh total count.rnThe analysis and interpretation from the ground magnetic and radiometric surveys arerncompared with that of the aeromagnetic and gamma ray spectrometric data on selected areas and arernfound to be well corroborated. From the result of all the enhanced maps the trends and dispositions ofrnthe inferred faults at the southern part are modified. Power spectrum technique is applied to estimaternthe depth to source of the magnetic body. The average depth for both the shallower source and deeperrnsource anomalies using the FFT analysis method are estimated to be 11.98m and 43.54m respectively.rnFrom all the interpreted maps composite map is produced which show the magnetic lineaments,rnaltered zone, and selected target area for further study and follow-ups.
