Providencia Geothermal Data

Geothermal Data for Providencia

The Providencia stratovolcano is extinct with no known hot springs or young volcanic deposits. The youngest volcanic deposits are the lithified and faulted ignimbrites that occur as valley-fill deposits in a deeply incised topography eroded into the felsic carapace of the island. An unsatisfactory K/Ar age (a biotite sample contaminated with chlorite) of 4 Ma has been obtained for the felsic carapace of the island suggesting that the last volcanic activity was several million years ago – probably in the Pliocene.
