ABSTRACT 
The main objective of this study is to define area favourable for gold mineralisation resulting from 
hydrothermal action, through the integration of physiographic, morphostructural and geologic data. The 
study was carried out in an area located at the eastern border of the Sáo Francisco Craton, northern of 
Minas Gerais state, and involved the use of TM-Landsat imagery at the scale of 1:100.000. The analysis 
was based on evidence of convergence of drainage and relief elements interpreted as faults, fractures and 
fouldings, which may indicate favourable areas for mineralisation. The results obtained from this study 
suggest that remotely sensed data may be incorporated into prospective models, providing a low 
cost/benefit relation.
