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.
