In this study ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) images are used for mapping purposes associated with mineral compositions in flat and gently sloping free crop cultivated areas in the northwestern Duero Basin. Several image band ratios have been applied to the ASTER multispectral dataset corresponding to the visible and near-infrared (VNIR) and to the short-wave infrared (SWIR) wavelengths. These band ratios enhance the absorption features related to both electronic and vibrational processes corresponding to iron oxides minerals and phyllosilicates minerals respectively. The results obtained show that in the northern and westernmost areas with Paleozoic basement, Neogene and Plio-Quaternary sediments, iron oxides minerals are more frequent. On the other hand, in the easternmost area, characterized by the Quaternary Tuerto and Órbigo river terraces, extensive areas show the existence of Al-bearing phyllosilicates. These results add information for geological, lithological and mineral prospection mapping in almost flat areas, where outcrops are scarce.
