(Grotta dell'Allume, Porto Levante, Isola di Vulcano, Isole Eolie, Lipari, Messina, Sicilia, Italia)
The Alum Grotto (Grotta dell'Allume) doesn't exist anymore because it collapsed in the 1940s. It was placed in the Faraglione Nico (see the relative mindat page).
The correct type locality of magnesioaubertite (found in 1982 and described in 1988 - IMA 1982-015) is not the Alum Grotto (as described in the type-description) but the Faraglione Ranni. Today it is still possible to find some rare samples of magnesioaubertite in its original T/L (Faraglione Ranni).
