The authors tested dating by counting small craters in a variety of presumed “old” and “young” regions of the moon, and got widely divergent results despite using standard methods and software.
They urged a high degree of caution, therefore, when trying to infer the age of a planetary surface.
The results also show that other factors, such as different target properties and the subjective identification of impact craters by different crater counters, may also affect crater counting results.
We suggest that dating planetary surfaces using small crater populations should be with highly cautious.
The abstract states: The small crater populations (diameter smaller than 1 km) are widely used to date planetary surfaces.
