ABSTRACT
Groundwater detection and supply in underlain crystalline basement complex rocks involves and require satellite image’s lineaments discernment, detection, classification, mapping and analyses of l their patterns and orientation in region of TalataMafara, Zamfara State, North Western Nigeria. This study is carried out as application of remotely sensing techniques for discernment and mapping of lineament for efficient ground water exploration and management. The primary data used is Groundwater detection and supply in underlain crystalline basement complex rocks Landsat Mss –ve image transparency while the secondary data are geological maps, hydrological maps and topographic maps..In this study, procum-2, an optical mechanical device to manually interpreted the digitally processed image, the basic element of interpretation which are jointly used for lineaments discernment, classification, mapping and analysis for structural map production. The extracted lineaments are statistically further analyzed to determine their lengths densities, intersections and orientations, and the result obtained is used to generate structural map for lineament density, frequency, direction and intersection, and represented with Rose diagram. The relationships of the mapped lineaments are synthesized from the registered image features as projected onto a topographic base map of the study area based on geologic and geomorphic interpretation and supported with ground truthing. The lineament analysis indicated that the area has numerous long and shot fractures whose structural strength are mainly in the NNE-SSW directions at an angle of 10-eas30o. The cross-cutting and intersectional lineaments are relatively high in areas around North-East, Central and South-East locations, (are projected to be productive hydrologic zones in the study area) and are relatively low in the other areas. The lineaments mapping led to delineation of ground water localised zones and are mostly feasible for further geo-physical survey, prospecting for sitting of productive and sustainable supply boreholes. It is found that of the 20 (with 4 in each segmented parts A-E) boreholes sunk in the prospective zones 15 constituting 75% of the total (with 3 in each segmented parts A-E) are found to be productive.
