Evidence of tectonic control of mineralization in Nigeria from lineament density analysis A Landsat-study

Lineaments study using aeromagnetic data over parts of southern Bida basin, Nigeria and the surrounding basement rocks

“…However, Figure 2 illustrates lineament-mineral association within the research area, as lineaments are observed associated with the occurrence of iron ore and cassiterite around Koton Karfi and Garaku areas, respectively. The work done by Ananaba and Ajakaiye [3], on the evidence of tectonic control on mineralization in Nigeria from lineament density analysis, agrees with this observation. Ananaba and Ajakaiye [3] showed good correlation between areas of high lineament density and the areas where there is occurrence of most primary minerals such as gold, iron ore, cassiterite, tantalite, clay and uranium.…”

Lineament Extraction from SPOT 5 and NigeriaSat-X Imagery of the Upper Benue Trough, Nigeria

“…It is believed that most of the sedimentary structures within the Trough developed as a result of Basement-seated transcurrent faults (Benkhelil et al,1998). Ananaba and Ajakaiye (1987) observed from Landsat imagery that the trend of the lineaments are predominantly north-east-southwest, northwest-southeast and north-south.…”

Analysis of Surface and Magnetic Lineaments in and Around Wase Area of Northern Nigeria

“…Correlation of areas associated with high gradient FVD anomalies with exposed basement rocks on the surface geology suggests the extrusion of the shallow magnetized intrusions to the surface. Historical knowledge and evidences from mineral map of Nigeria [6] suggested presence of mineralization in the study area. Therefore, areas associated with high gradient FVD anomalies may suggest DOI: 10.9790/0990-0501025262 www.iosrjournals.org 56 | Page association with mineralization.…”

“…Generally, primary mineralization of an area depends to a large extent on the structural geology of the host rock because the geologic structures control the emplacement and localization of the ore deposits [7]. Within the Nigerian basement complex region, correlations were observed between areas of high lineament density and mineral occurrence [6]. It is plausible therefore that prior to any mineral exploration programme, a comprehensive mapping of geologic structures should be embarked in the area.…”

“…Mineral exploration usually involves regional reconnaissance, surface and subsurface mapping, ground geophysical surveys and actual drilling [5]. Evidences from landsat studies in Nigeria [6] and information from the published mineral map of Nigeria (NGSA) showed that the NNBC is associated with primary mineral occurrences. Such minerals may include iron, gold, lead-zinc and uranium.…”
