Abstract: Two dimensional (2D) Euler de-convolution techniques was applied on the selected profiles of reduced ground magnetic data collected in Homa Hills area. Depth estimates of causative bodies were quantitatively analysed in the anomalous areas on the residual magnetic intensity map. These depth estimates were later used as start-up parameters for 2D-forward modelling using mag2DC software. Results of the analyses show that the magnetic anomalies in the region are caused by shallow-seated thermal intrusive structures of carbonatite origin.2D-Euler solutions revealed subsurface faulting activities up to a depth of 250m and the presence of fluid-filled zones within the survey area which are marked by absence of magnetic sources. It is postulated from 2D-forward modelling that the heat sources are shallow intrusive bodies such as dykes, plugs and sills taping from a deeper magmatic body and that the thermal intrusive structures form along fracture zones.
