Description:
Although ~50 radiometric age analyses have been performed on Etna, and there
are many historical references, these are not enough to temporally constrain the geo-
logical evolution of the volcano. In particular, a new stratigraphic framework based
on lithostratigraphic and unconformity-bounded units has pointed out the presence
of some stratigraphic uncertainty that can be resolved only with radiometric dating.
For this reason, a dating project applying the
40
Ar/
39
Ar incremental heating technique
started in 2002. The results obtained improve our understanding and provide con-
straints for Etna’s geological evolution; in addition, they show that the applied tech-
nique is very useful for dating young basalts and quantifying the hiatus represented
by unconformities, as well as for understanding their meaning.
