Local gravimetrical profiles divide the Camaqua Basin in a south region, along with a basement, and the Parana Basin showing the possible density relationships between different sediments of Godwana with low density (0 and +1), and the sediments of the Guaritas Formation in the Camaqua Basin.
Geophysical methods permit to obtain gravimetrical, density, and physical information.
Structural compartments were identified from the variation of preferential direction of lineaments taken from LANDSAT TM images analyzed through preferential lineaments and gravimetrical contrast values.
