Tin Tarabine is located in Central Hoggar, at the junction of three terranes of different geological and tectonic histories. The late Pan-African E-W compression produced in the Tuareg shield N-S trending folds linked to mega-systems of shear belts and strike-slip faults which dissect the Tuareg shield into N-S trending branches and blocks of many hundred kilometers lateral displacements. Remote sensing has been used to define the Pan-African deformation. Various treatments such as Contrast-enhanced Red-Green-Blue (RGB) composites, Principal Component Analysis, Band Ratios and Directional Filters have been applied on Landsat 8 OLI Satellite images of Tin Tarabine region. The aim of this study is to highlight the impact of major shear-zones on the region of study. The structural mapping has allowed us to identify and characterize their structural expression. Most of the structures found include faults, folds and lineaments with the highest lineaments densities obtained being mainly oriented NNE-SSW, NE-SW, NW-SE and N-S. We consider that during the final compressive phase the unquantified E-W shortening may have been absorbed by lateral movements along shear zones with a main sinistral component.
