The geophysical data portray with sufficient detail all of the lithological units and structural features present. The results suggest that the granitoid domains are formed by numerous small to medium-sized plutons. The existence of several generations of magmatic episodes has a significant impact on the development of a regional tectonic model. The magnetic data provided a better definition of the actual pluton shapes and several highly magnetic late-orogenic plutons were reliably identified. Relic F1 fold hinges were recognized in the Hounde and Boromo greenstone belts. The D1 penetrative structures are generally affected by the D2 transcurrent shear zones, which often form as well the granite-greenstone belt boundaries. Previously unreported S2 shear zones including the Bossie shear zone, transecting the Sideradougou granitoid domain and abundant small-scale shear zones affecting all of the lithologies represent prospective areas for gold exploration. Airborne gamma-ray spectrometry data aided in the mapping process in areas with less regolith cover including erosional ridges and parts of the Banfora greenstone belt. The magnetic data revealed at least three generations of doleritic dykes crosscutting the western Burkina Faso. specialized West Africa Burkina Faso Paleoproterozoic Airborne geophysics Remote sensing Structural analysis 066 126 190 1-4 48-69 2011 0301-9268 https://www.documentation.ird.fr/hor/fdi:010054105 10.1016/j.precamres.2011.08.002 0301-9268 [F B010054105] https://www.documentation.ird.fr/hor/fdi:010054105 https://www.documentation.ird.fr/intranet/publi/2011/11/010054105.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2011-11-30 2017-08-23 fdi:010054105 fre
