ABSTRACT
Dagbala and environs is of the Basement Complex of Nigeria which are situated in Akoko-Edo, having latitudes and longitudes of 7° 19' 45"N to 7° 23' 20"N and 6° 12' 0"E to 6° 15' 50"E respectively surrounding the Igarra Schist Belt. The case study entails the delineation of fractures and the materials and methods that are used to carry out the study are Satellite Imagery, ENVI Classic, PCI Geomatica, ArcGIS, Rock wares and Rose Diagram. These materials and methods are used for the extraction of landsat 8 images, image enhancement, identification and extraction of lineaments, generation of lineament maps, lineament density map, trend analysis and lineament length percentage. The lineament analysis indicated that the area has numerous long and short fractures whose structural trends are mainly in the NW - SE and NE – SW direction. The extracted lineament analysis reveals that they are forty-four (44) fault lines in the study area. Its maximum lineament length is 1046.566m and its minimum is 67.08204m. The lineaments are relatively high in areas around the south-western, north-eastern and southern parts of the study area and relatively low in the other areas. The rose diagram reflects that the rocks found in the study area has undergone several tectonic phases and has been acted upon by heterogeneous stresses. The discovery and delineation of the lineaments will serve as a guide for further studies and for good development policy
