Abstract:
In order to fully assess the potential of Homa Hills Geothermal prospect, the heat
source which is one of the main features of a geothermal system had to be located
based on its perturbation on the gravity field. Ground gravity survey was
conducted in an area covering about 76 km2 and the data processed to remove all
other effects which are not of geological interest. Qualitative interpretation was
attempted and cross sections drawn across the anomalous areas on the complete
Bouguer anomaly map. Quantitative interpretation attempted involved both Euler
Deconvolution and 2-D Forward modelling. The parameters obtained from Euler
Deconvolution were used as the start up parameters for 2-D Forward modeling.
Well clustered Euler solutions were obtained at a shallow depth of approximately
200‐750 m which is consistent with the modeled shallow dike like intrusive
probably of carbonatite origin.
