The present work is a contribution to the knowledge of tectonic and metalogenetic characteristics of a complex geology area, located between the Sao Francisco and Amazonic cratons. The study was developd based on interpretation technics obtained from spacial characteristics of remote sensing products derived from TM-Landsat and SLAR images and aeromagnetic data. Structural lineament analysis and interpretation were directed toward the kinematic definition, general characteristics of shear belts as well as their structural/tectonic implications in the control of important known mineralizations of asbesthos and Cu, Pb and Zn massive sulfide deposits. Besides, propositions of tectonic evolution of the area in study is presented as a contribution to the understanding of the regional geology. The same interpretation methodology which was taken as a regional basis, was tested on a preselected area, where structural lineaments were integrated with Cu, Pb and Zn geochemical images produced by Geographical Information System (SIG). The results obtained in both regional and semi-detailed scales show that the already know mineralizations in the area are tectonically controlled by a fault system associated to a shear belt. Trough the structural lineament analysis, together with geological data, four important deformational phases were recognized in the area, related to different sorts of stress, sometimes compressive, sometimes extensive, associated to transpession and transtension systems. Kinematics differs along the main structural lineaments, which were developed from the Archean to the Tertiary, during the tectonic evolution of the studyed area.
