Structural mapping in a sub-tropical region using Landsat-8 and SRTM data: A Case study of Deng-Deng area in Eastern Cameroon

The paper examine the capabilities of Landsat-8 and SRTM remote sensing data for regional scale structural mapping in a sub-tropical region, which is challenging due to heavy vegetation. Fracture sets are defined using statistical characterization of fracture orientation and genetic parameters. Detailed analysis of the overall structures led to the identification of two major networks corresponding to dextral and sinistral shear zones mainly oriented NE-SW. Fields investigation shows that the area has recorded structures such as foliation, intrafolic boudins, mylonitic schistosity, S/C fabrics and fractures, organized into three phases of deformation D1 to D3 and geological formations include intrusive granite in a metamorphic basement. Remote sensing results are consistent with field data.
