Nine sites of the Miocene andesitic intrusions in the Pieniny Mts, Carpathians (Poland), sampled in 1999, were K-Ar dated. The dating was carried out on whole rock, groundmass and monomineral (amphibole) fractions. The present paper completes the K-Ar age study of andesitic intrusions in the Pieniny Mts, the first part of which involving 17 sites was published in 1999. The 1999 samples included both the 1st phase and the 2nd phase intrusions. The K-Ar ages of the 1st phase intrusions, 12.5 to 10.8 Ma, fall within the age range (13.5 to 11 Ma) of the majority of andesitic rocks dated previously. A 2nd phase northern dyke at Mt Wżar (Kluszkowce quarry) yielded the K-Ar whole rock date of 10.8 Ma, the youngest radiometric date recorded from andesitic intrusions of the Pieniny Mts.
