Resumo
The Araguainha Dome, located on the border between the states of GO and MT, in the Midwest of Brazil, is the largest impact crater in Latin America (diameter ? 40 km). Geophysics has important tools for the characterization of this type of structure, and one of these tools is the analysis and interpretation of magnetic susceptibility (MS). This research proposes an MS analysis integrated with other geological and geophysical data. The result of this work is a magnetic map which contribute to the recognition of the impact structure showing the annular distribution of MS values with higher values around the central uplift.
