The geophysical-geological comparison of the Paranaguá Terrane confirms the accuracy of the geophysical with lithogeochemical data.

The mobility of radionuclides in the research area can be explained by two factors: mass movements (characteristic in the study area) and natural mobility.

The gamma-ray spectrometric method could be used as a tool in mass movements studies associated with geomorphological techniques.

Gamma-ray spectrometry is an important tool in geological cartography, especially for granitic bodies.
