Abstract

In this study, photogeology is coupled with pre-existing well data to examine the impact of lineaments on aquifer productivity in an area where access to potable water is a serious challenge. The photogeological study of the peneplain portion along the Keve - Amoussoukope (SW-Togo) road has revealed a dense lineament network mainly represented in the NNE-SSW (N10-N20), NE-SW (N30-N50) and ENE-WSW (N60-N80) directions. The network components are dominated in number and weight (cumulative length of lineaments or fractures in a given direction) by the NE-SW lineament family. The brittle tectonic data from the field and the geological map confirm the network characteristics and validate the fracturing state of the gneisso-migmatitic formations belonging to the internal units of the Panfrican Dahomeyides Belt (600 ± 50 My). The lineament or fracture network density confers discontinuous aquifer properties to the gneisso-migmatitic formations in the study area. In fact, the major lineament and well coupling shows that wells with high flow rate (Q > 5 m3/h) are associated with the NE-SW dominant lineament network. Statistical analysis established with well data in the area highlights a large variation in productivity of the wells, probably linked to the lithological heterogeneity.
