Contribution of Landsat 7 ETM+ imagery to the litho-structural mapping of east-central Côte d'Ivoire (West Africa)

Control of different network fractures is an important tool in the Mining Research in the Birimian of West Africa. The objective of this work is to highlight the fractures and major formations of central-east of Ivory Coast, using Landsat 7 ETM+ images. We have extracted lineaments and the hydrographical network from an analogic analysis supplemented by numerical analysis using directional filters. Next, we determined the limits of lithological using textures and colors. A sketch map of lithostructural was thus obtained.Several directions of major fractures were mapped. These directions are: sinistral submeridional N00
