Abstract

The Bindiba gold district study in the East Cameroon region was done using a combination of Landsat 8 ETM image processing techniques, SRTM imagery and fieldwork. The various digital processing methods of treatment applied such as color compositions and component analysis showed lithological differentiation of the different formations of the study area. Directional filtering and treatments such as the Sobel have made a good linear mapping where we have been able to list more than 293 lineaments in which two types have been distinguished. The type I lineaments or penetrative lineaments correspond to schistosity trajectories. This interpretation is confirmed from field data which revealed schistosity plans mainly oriented NE-SW. Type II lineaments or non-penetrative lineaments are characterized by greater cartographic continuity and lesser spatial density. These lineaments thus represent the fracturing of the study area. The results of this lithology and linearization mapping, based on the superposition of the different images from the treatments and the field data, made it possible to identify the zones favorable for gold concentration and highlighted two gold mineralization corridors. This is the N30-35E steering corridor and the N110-135E steering corridor.
