Geological Lineament Extraction Using Landsat 8 (OLI) in Parts of Osun State, Southwestern Nigeria

Christopher Oche Albert | Alaga Abayomi Taofeek

Abstract: Geological lineaments are essentially straight or curve lines on the earth surface that gives information about the subsurface structures. Economic mineral resources accumulation, fracture zones for groundwater, engineering (slope stability, foundation study, sites selection in the construction of dams, roads, bridges, etc), earthquakes and hazard monitoring, are related to a better understanding and interpretation of lineament. Lineament in parts of Osun State was extracted from Landsat 8 (OLI) image both manually and automatically. Comparison was done between the manually and automatically extracted lineaments which led to further analysis to be done from the manually digitized lineaments. Lineament interpreted was verified from geological map and with known structural features of the study area. Result from evaluation of Lineament indicates a NNE-SSW as the major structural trend. Also the deformation characteristics of the rocks types were known based on the density, intersection and length of lineament of the study area.
