The observed magnetic anomalies are explained by sources equated to magnetized dykes, tabular bodies and semi-infinite slabs running NNE - ssw and lying at depths ranging from 2.5 km - 8.0 km. These may be attributed to intrabasement faulting in the magnetic basement and intrusives into the weaker zones of the basement. The observed relief of the magnetic basement may be attributed to the faults in this region. Several steep flanked highs and a regional prominent flat-topped terrace were noticed from the bathymetry.

Abstract


The observed magnetic anomalies are explained by sources equated to magnetized dykes, tabular bodies and semi-infinite slabs running NNE - ssw and lying at depths ranging from 2.5 km - 8.0 km. These may be attributed to intrabasement faulting in the magnetic basement and intrusives into the weaker zones of the basement. The observed relief of the magnetic basement may be attributed to the faults in this region. Several steep flanked highs and a regional prominent flat-topped terrace were noticed from the bathymetry.
