Abstract
The fact that geological formations and structures appear as ground surface features and are observable on remote sensing data
sources, permits the use of. such data ources in this type of investigation. The geological features themselves also display
characteristics which are either distinctive, or, allow inferences to
be made as to their attitude. Landsat images served as the main sources of information
studied but these were supplemented by SLAR and aerial photographs for detailed study of critical areas. Field checks were carried out along selected routes for ground truthing of image interpreation. Thus, the image-study and ground-truth verification of the are of study shows the banded gneiss as the most extensive rock type within which other rock types occur. It is variably migmatised with several types of migmatites distinguished. It is interpreted as the
oldest rock unit and basal to the metasediments. Two metasedimentary groups are distinguished structurally; an earlier group of generally arcuate formations and a later group of the formations which trend N-S. The later group forms two major N-S belts; the Zuru Schist Belt (ZSB) and the Kusheriki Schist Belt (KSB). These belts, as
1:1,000,000 images revealed and were confirmed by field observation ock types; relatively more abundant metapsammites
in the ZSB while meta-argillites are ominant in the KSB.
