摘要
The existing practice for characterizing the time of a metamorphic event by the average mean of radiogenic mineral dates gives a false idea about the event duration. In the present communication this practice is discussed from the viewpoint of regional geology and geodynamics. Conclusions about the interpretations of radioactive mineral dates for the mineral event duration and the metamorphic event duration are also made.
