5.3 Mineralogical Composition The mineralogy of the dunes and sand sheets is analyzed by the method described in Sect. 4.5.1. The output of this method is images in which the absorption depths corresponding to the minerals of interest are stored in different channels. By superimposing these absorption depth images onto the original OMEGA images, mineral absorption depth on the surface
