• Resumen

  • Fission-Track Method, FTM, urn applied to obtain ages of Macusanite glasses from Peru. In order to obtain the data two irradiation were carried out at IPEN-CNEN reactor (Brazil). Natural uranium and thorium thin film neutron dosimetry together with a lho f8.5x I O'1 a ' were used to obtain the ages. The apparent ages were corrected using the Plateau Method and the Size Correction Method. The results showed a mean value close to 4.7 Ma, in agreement with some ages obtained using other dating methods.
