Abstract
Gravity field survey has been carried out in the Omo basin over the
detail grid. The grid comprise nine, 48 km long gravity traverses, 4 km
apart with gravity stations on a 1 km interval. The gravity data have
been collected with the La-coste and Romberg Model G-1105 geodetic
gravimeter occupation in conjunction with the post processed Fast
static GPS-data acquisition using Trimble 5700.
The data were processed, analyzed and presented in contour maps and
therefore are interpreted to draw conclusions in terms of basin
formation.
The result shows a well-defined sedimentary basin bounded by northsouth
striking major structures. The Omo basin sedimentary potential
has thickness of more than 3 km as deduced from the processed
results, besides; its width is about15870.5 m.
In addition to its academic importance, the study will have a
considerable contribution in exploring the country’s hydrocarbon
potential.
