Resumo | Des produits integres ROS ont ete evalues pour la cartographie geologique de la region granitique centrale de la Serra dos Carajds (CSCG), dans la province minerale de Carajds, dans la portion bresilienne de l'Amazone. La region CSCG est un exemple typique des plus anciens complexes granitiques anorogeniques du Craton amazonien d'tige paleoprotezozoique. Le batholite est caracterise par un terrain vallonne irregulier de faible elevation entoure d'un ensemble de collines et de plateaux paralleles relies aux gres archeens et aux roches volcaniques encaissantes. Le granite est mal cartographic au moyen d'une information geologique partielle pour des secteurs restreints de l'intrusion. La region est recouverte de foret tropicale humide avec des canopees complexes a plusieurs niveaux et comportant de nombreuses especes. La recherche est basee sur l'integration numerique des donnees aeroportees ROS en polarisation C-HH (Wide-SAREX'92) et RADARSAT-l (faisceau standard 5) avec des donnees Landsat TM et des donnees aeroportees de rayon gamma (compte total, uranium et thorium). Les produits integres aeroportes et satellitaires ROSfTM permettent de rehausser les caracteristiques topographiques du relief grace ala variation des angles d'incidence des images ROS, apportant ainsi une information complementaire pour la cartographie geologique. De plus, l'integration a donne des produits rehausses qui temoignent de controles geobotaniques dus aux changements du couvert vegetal relies etroitement aux variations de la geologie. Les donnees aeroportees et satellitaires ROS integrees avec les canaux gamma individuels constituent un outil puissant pour la cartographie geologique et elles permettent aussi de documenter les modeles geologiques et exploratoires actuels de la region. Les resultats de cette etude apportent une information geologique significative nouvelle. Cinq unites geologiques ont ere cartographiees pour la premiere fois. Deux grands systemes de lineaments ont aussi ere caracterises. D 'une signification particuliere pour l'exploration, on a determine des zones d'anomalies d'uranium le long du lineament NO-SE et une association entre le lineament oriente N-S et une limite radiometrique dans les reponses de l'uranium, permettant de definir potentiellement des zones affectees par des processus secondaires. Le~ resultats de recherche presentent une possibilite reelle d'utilisation des donnees integrees ROS en tant que routine pour la cartographie geologique et les programmes d'exploration dans la region de l'Amazone. particulierement dans les terrains granitiques ou les donnees de spectroradiometrie aeroportee aux rayons gamma sont disponibles. SUMMARY SAR integrated products were evaluated for geological mapping of the Central Serra dos Carajds Granite (CSCG) area, in the Carajds Mineral Province, Brazilian Amazon. The CSCG is a typical representative ofthe oldest anorogenic granitic complexes (~l the Amazonian Craton with Paleoprotcrozoic age. The batholith is characterized by an irregular hilly lowland terrain surrounded by a set ofparallel hills and plateaus related to Archean sandstone and volcanic country rocks. The granite is poorly mapped with sparse geological information related to small sectors ofthe intrusion. The region is covered by tropical rainforest with complex, multi-level canopies and numerous species. The research was based on digital integration (if airborne C-HH SAR (Wide-SAREX'92) and RADARSAT-l (Standard Beam 5) with Landsat TM and airborne gamma ray channels (Total Count, Uranium and Thorium). The airborne and spaceborne SARfTM integrated products enhanced topographical features due to the variation of incidence angles of the SAR imagery, thus providing complementary information for geological mapping. In addition, the integration produced enhanced products which show geobotanical controls due to changes in the vegetation cover which is closely related to variations in the geology. Airborne and spaceborne SAR integrated with isolated gamma channels have provided a powerful tool for geological mapping and also favoured insights concerning the current geologic and exploratory models in the area. Results of this study have revealed significant new geological information. Five geological units are mapped here for the first time. Two large lineament systems have also been characterized. Of particular significance for exploration are anomalous U areas along the central NW-SE lineament and the association between a NS-oriented lineament and a radiometric limit in U responses, probably defining areas affected by secondary processes. The results ofthe investigation offer a real possibility of using SAR integrated data as a routinefor geological mapping and exploration programs in the Amazon Region, particularly in granitic terrains where airborne gamma ray spectrometry data is available. |
