Description

For the purpose of dating by U-Th-Pb ratios, the distribution of trace elements across single natural zircons has been measured by PIXE in conjuction with a proton microprobe. In addition trace element concentrations have been measured for a number of zircons from the same source. The present work supports the view that in general the apparent age decreases as the amount of U and Th increases, possible due to radiation damage within the crystal. (orig.)
