%X Geological alignments reflect the features of the subsurface. These features are essential for studies of economic geology and are likely to be interpreted on satellite images. The present study aims at extracting relief and drainage lineations and lineaments, using the CCD-CBERS-2B images aiming to analyze the structural control metallogenic in the scale of 1:50.000 of Currais Novos Topographic Map. This area is at the central-south part of the Mesoregion Central Potiguar, economically characterized by mining, activity usually related to structural control. The steps of the work were: creation of a georrefered database; image restoration; transformation through main component; extraction of relief and drainage alignments; and rose diagrams. After extracted, the lineations and lineaments were interpreted as possible fracture systems. The study of the proprieties of alignments characterizes the homologous zones, which indicate different geologic-structural domains, which probably influenced the metallogenesis of mineral occurrences, due to the structural control.
