Abstract

This paper make use of gamma-ray spectometric data<br>to compare two geological unities with granitoid<br>composition from Serra do Mar Suite and Paranaguá<br>Domain, southeast of Paraná state. This rocks<br>presents different evolution during late Proterozoic.<br>The obtained results shows that the images of eTh, K<br>and eTh/eU ratio and the parameter F=K*eTh/eU,<br>correspond to gechemical indicator of magmatic<br>differentiation, alcalinity and a avaliation of the<br>radionuclides mobility on the terrain, which permit<br>show the differences between the mentioned rocks.
