		<abstract>This paper uses images of TM/Landsat 5 sensor, altimetric (SRTM) and airborne geophysics data to the reconnaissance of the geology and the gold mineralization context of the Tapajós Mineral Province northwestern portion (Pará and Amazon states - Brazil).  Two regions were selected: areas of the Seta de Ouro and Chico Torres shear zones. Based on TM sensor, drainages were interpreted, beyond main lineaments. Using analytic signal amplitude and first vertical derivative images, magnetic lineaments and units were identified, like mafic dike swarms (~ 180 Ma) characterized by NNE-SSW direction. The images of K, eTh, eU, K/eTh, K/eU, F parameter and of radioelement normalization were producing, beyond the color compositions. These products allowed the visual interpretation of the gamma-ray spectrometric units characterized by possible hydrothermal origin, and correlated with interpretation of structures identified by remote sensing. Other step utilized consisted in the gamma-ray spectrometric signatures extraction of the gold occurrences mapped by CPRM, and the application of the Principal Component Analysis to the enhancement of potential hydrothermalized areas. It was possible to enhance targets associated with the Seta de Ouro and Chico Torres shear zones, and characterized by N30W and N40W directions, respectively.</abstract>
