摘要：
The analytical data of U-Pb multigrain analyses of zircons separated from a sample of rapakivi granite at Rodon, central Sweden, have been plotted in a concordia diagram and yield an upper intercept age of 1513 +/- 5 Ma. This age is sligthly younger than the intrusive activity at 1590 to 1540 Ma of rapakivi granites in southwestern Finland and central Sweden.
