| Popis: |
The Mara Rosa Magmatic Arc is characterized by limited outcrops, deep weathering and thick regolith cover and lack of systematic mapping. This area is covered by highdensity aeromagnetic and aerogamaespectrometric data. The geophysical images provide an overview of the geological units. In this paper, these geophysical data were successfully used to highlight the relationships between the principal main lithologies, as well as their internal structural framework and boundaries. Enhancement of gamma-ray spectrometry data showed their usefulness in mapple subtle compositional variations in the area, which concur with and complement available geological data. |
