                         Maranh{\~a}o, north and northeast regions of Brazil. The 
                         vegetation is constituted of crop areas and grassland. The 
                         methodology is based on the Cr´osta technique applied to six and 
                         four bands of the TM Landsat 5. The results showed that the 
                         application of the technique to four bands was more effective to 
                         detect iron oxides. In the center-north to northeast of the study 
                         area, where a wide dissected plateau occurs, potential iron oxide 
                         concentrations are observed, which are coincident with the main 
                         duricrust registered occurrences and roughly with the lateritic
