Abstract

In the Pieniny Volcanic Arc (Miocene), the northernmost volcanic arc of the West Carpathians, hydrothermal activity produced some ore-bearing veins associated with moderate-size andesite intrusions. They were subjected to prospecting and mining for gold, silver and lead for a short period at the beginning of the 18th century. K-Ar dating of secondary chlorine-biotite from the mineralized zone at Mt Jarmuta, yielded a K-Ar date of 11.35±0.45 Ma. This K-Ar date fits well with the average K-Ar age (11.34±0.50 Ma) obtained on unaltered andesite sills exposed at Mt Jarmuta. It indicates a close age-relationship between the emplacement of the andesite intrusion and the subsequent ore-mineralization during Miocene (Sarmatian) time.
