Abstract

Nowadays there are many geophysical techniques of<br>rock fractures mapping as GPR, electromagnetic and<br>dipole-dipole geoectrical sounding. These methods<br>don’t give information about the content of fracture<br>zone, that can be fullfilled of clay. Using nuclear<br>methods as gamma spectrometry and radon<br>emanometry become possible to identify the nature<br>of mineral composition of fracture material and to<br>study the freshwater circulation using the radon<br>transport by water. In this work the integration of<br>nuclear, GPR and geoelectric techniques in Itu<br>granitic intrusives became very interesting because it<br>was possible to find and identify fracture in granitic<br>rock with clay and freshwater content.
