| dc.description.abstract | The study area covering an area ~1400 km2 lies within the Tanzania craton and is among the onshore sedimentary basins in Tanzania. There are limited geophysical and geological associated research works that have been conducted in the area. The area is underlain by economically potential geological structures, hence, the use of magnetic and gravity survey methods to disclose these economically potential geological structures. Geographically, it is located at the western part of the Eyasi basin at latitudes 3oS and 5oS and longitudes 33oE and 35oE respectively. Ground gravity survey and airborne magnetic survey methods were employed in the data acquisition. The field data correction and error reduction were applied to the two raw datasets on the field after which, Oasis Montaj 8.4, and ArcGIS 10.3 were used to process, enhance, model the reduced and corrected both datasets as well as to produce maps. Low-to-moderate-to-high gravity and magnetic anomalies were obtained in the BA and TMI reduced to pole at low latitude with many of these anomalies trending NE-SW by which the Metasediments and Metavolcanics can be said to be part of the causative structures of these anomalies with cross-cut NW-SE faults. Quantitatively, modelling of gravity data revealed depth ranges of < 0.5 km in the west to > 1 km to the east. Results derived from Euler deconvolution reported depth range of < 1.8 km in the western part of the basin and > 2.2 km in the eastern part of the basin while spectral analysis gave depths ~ 0.7 km in the west, >1 km at the central part and > 2 km to the eastern part. Part of the depths represents unknown sediments. Depth estimates from the three methods suggest adequate burial depth to allow maturation of hydrocarbons. The basin has proven to be potential for hydrocarbons prospectivity and further work is highly recommended eastward of the basin. | en_US |
