Investigating heat and magnetic source depths in the Soutpansberg Basin, South Africa: exploring the Soutpansberg Basin Geothermal Field

Article scientifique 2016 Anglais

Résumé

The research was conducted to seek geothermal energy potential in the Soutpansberg Basin, located in the northern part of South Africa. The depths of the potential heat sources were computed from the radially averaged power spectrum of airborne magnetic data. Shallower magnetic sources were delineated using the Euler deconvolution method. An anticline at depths of 2.0–3.5 km was delineated in the central part of the basin. Potential magnetic and basement heat sources exist between depths of 4.8 and 11.1 km. Airborne magnetic data sets with larger window sizes are preferred for depth computations, as they preserve spectral signatures of deeper sources and reduce the contribution of shallower sources. The research clearly highlighted evidence for the existence of the Soutpansberg Basin Geothermal Field.
