ABSTRACT 
In this paper we discuss the integrated use of geophysical, geological and TM-Landsat data to 
determinate and characterized lithological and structural controls of Au occurrences in the Crixás 
greenstone belt. We use magnetometric and TM data to map structural lineaments, foliations and faults, 
and geological data to evaluate relations between structural and lithological aspects. With the correct 
position of Au occurrences in the study area we test several combinations of geophysical and TM-data 
with a real time shadowing display resource to evaluate directional controls of the Au orebodies. The 
methodology used showed excellent results possibiliting the evaluation and characterization of the 
controls for Au occurrences. With the use of real time shadowing display resource we have got an 
optimization in the interpretation procedures with a increase in the accuracy and quick.
