A comparison is made between lineament analyses made from side-looking radar (SLAR)imagery, LANDSAT and aerial photographs from an area on the Lamurde anticline (Benue Valley) and from an area of ring dyke complexes (Jos Plateau), Nigeria. Fault lineaments are, in general, well expressed on side-looking airborne radar with the exception of those lineaments orientated parallel or subparallel to the radar look direction. Look direction and radar incidence angle influence lineament detectability. Specifically the lineaments oriented perpendicular to the Sun azimuth direction on the LANDSAT image were over-represented. LANDSAT, SLAR and aerial photographs can be used in a complementary way; the first two for reconnaisance-type surveys and lineament analysis, the third for detailed surveying.
