The analyses indicated RGB/572 and RGB 452 color composites. which were enhanced by linear decorrelation stretchs. The unambigously discrimination of these rock units shown in the color composites, enables us with a quick and unexpensive tool to map these rocks, which besides bearing gold mineralizations, constitute an important stratigraphic guide throughout the Brasilia fold belt.  aBrazil  acarbon  agold  amineralization  aCarbono  aCerrado  aMineralização  aAbadia dos Dourados  aBrasil  aCristalina  aGoias  aLuziania  aMinas Gerais  aOuro  aParacatu1 aSILVA, F.
