Abstract
Radar imageries revealed three major geomorphological units and a series of long, short and arcuate lineaments. The different lineament systems seem to delineate blocks containing folded structures. The metamorphosed terrain is easily recognisable as a highly deformed area. Including the metamorphosed rocks, three lithologic units have been recognised and demarcated in the area; consequently a radar-geological map at 1:50,000 scale of area 20,000 km2 based on interpretation of radar imagery and a brief period of field work has been produced from this study.
The radar imagery studies have disclosed regional lineaments of tectonic origin, and indicate that an important tectonic episode occurred in the Oban massif and post the Precambrian period.
