Lithofacies discrimination has been conducted using the full- and dual-polarimetric ALOS/PALSAR data in the semi-vegetated Kalgoorlie area, WA, Australia and vegetated Lao Cai area, Northern Vietnam. In the Kalgoorlie area, characteristic features of topography, vegetation and surface roughness affected by the difference of geological units were noticed from simple scatter component image of PALSAR and multi frequency image using PALSAR and ENVISAT/ASAR data. In the Lao Cai area, the relation between polarimetric characters data and lithofacies are not recognized due to the thick vegetation and steep slope, however, the geological boundaries between metamorphic, igneous and sedimentary rocks are detected by using coherence information which is computed within InSAR processing.
