Zone

Characteristic Anomaly

A

Zone showing pattern at the SE lower corner of map showing lowest amplitude (~−1445.6 g.u. to −1756.8 g.u), further analysis in relation with geology and structural maps shows the contrast of high density pyroclastics overlying high density basement, probably tectonic events, faulting. The rocks here have low density variations compared to the basement rocks.

B

Zone of broad northerly trending bound feature in the eastern part of the area; indicating moderate amplitude (~−680.2 g.u. to −994.3 g.u). The area is covered by basalt, igneous rock, granite and acidic metamorphic rocks. These are rocks whose densities are closer to the basement density.

C

Zone C has the outstanding feature with north westerly continuous trend stretching from the SE to the west having low amplitude (~−1102.2 g.u to −1396.8 g.u). Correlation with geological map indicates that the surface is covered with pyroclastics, andesites, trachytes, phonolites, sandstone, greywacke and Eolian unconsolidated rock all overlying the basement. The rocks here have recognizable density variations from the one by basement rocks.

D, E, F

Zone of northerly trending parallel features covering the northern part; showing alternating moderate to high amplitude (~−501.2 g.u to −994.3 g.u). The geology of the sections is mainly of granite and acidic metamorphic rocks, andesites, basalts, and pyroclastics.
