Abstract

Remote sensing investigations carried out in French Guiana mainly with radar data is allowing to differentiate morphologies and lithologies, and to map large-scale structures, particularly in the volcanosedimentary units of the Northern Synclinorium. For the Palaeoproterozoic series, airborne total magnetic field provides better arguments to highlight structural features, while airborne radiometry delineates more accurate contrasts for plutonic varieties. Airborne total magnetic field and SAR data provide information about the basaltic dykes, which cut through the Proterozoic terranes. Other results concerning the geomorphology and hydrogeology of the coastal plain have been obtained (fan-shaped arrangement, capture, migration of the estuaries, etc.). In the particular case of the preserved rain forest of French Guiana, the SAR backscattering is mainly due to the shape of the homogeneous canopy modulated by regional morphology
