                         high-resolution gamma ray data (K, U, Th, TC channels) were 
                         evaluated for geological studies in the {\'A}guas Claras region, 
                         site of the important Cu-Au (W-Bi-Sn) deposit in the central part 
                         of the Caraj{\'a}s Mineral Province (CMP), Brazilian Amazon. 
                         Airborne high-resolution geophysical digital data were provided by 
                         VALE mining company and were integrated with PALSAR images through 
                         pseudo-tables and IHS transform. The RGB-IHS integration of PALSAR 
                         with gamma data produced image patterns with color variations 
                         expressing changes of the bedrock radioelements, while SAR 
                         contributed to the enhancement of textural patterns. The gamma 
                         Total Count (CT) responses include a contribution of K, U, and Th 
                         radiations and were more reliable for rock discrimination. The 
                         studied area encompasses Archean units of the Gr{\~a}o Par{\'a} 
                         Group (metavolcanics and banded iron formations) and the 
                         {\'A}guas Claras Formation (sedimentary rocks), the western part 
                         of the Central Serra dos Caraj{\'a}s Granite (1.88 Ga) and 
                         extensive tertiary lateritic covers. At the time of the Central 
                         Granite emplacement the evolution of CMP was characterized by a 
                         brittle transpressive tectonic, locally transtensive. The systems 
                         of structural lineaments striking NW-SE were enhanced under 
                         ascending pass, while NE-SW systems were highlighted with 
                         descending pass. The structural arrangement suggests the presence 
                         of transtensive structures NW-SE and ENE-WSW (Y and T, 
                         respectively, in the theoretic empirical model for strike-slip 
                         shear zone), important for the migration of hydrothermal fluids 
                         responsible for the re-concentration of the ore elements in the 
                         {\'A}guas Claras deposit. The RGB-IHS integration of PALSAR with 
                         gamma K showed spatial relationships of Y and T structures with K 
                         anomalies.",
