Abstract :
Using spaceborne Radarsat and SPOT data, and airborne geophysical data (magnetometry and radiometry) as well, the mapping of the lithostructural units of the Nyanga syncline is enhanced. These data, analyzed with the help of a GIS, contribute to the improvement of the geological knowledge.
