The present study focuses on the analysis of lineaments affecting Paleocene-Miocene formations in the Ader Doutchi sub-basin (Tahoua region, Iullemmeden basin, central Niger). The main objective of this study is to carry out a geostatistical analysis of the different lineamentary structures affecting the Bouza and Keita regions. The methodological approach adopted is based on the use of remote sensing techniques and GIS tools to analyze LandSat 8 images and to compare them with field data. This methodological approach facilitated the identification of five primary fracture families, characterized by orientations ranging from N0° to N40°, N40° to N80°, N90° to N130°, N130° to N150°, and N160° to N170°.
