Cossaite from
La Fossa crater, Vulcano Island, Lipari, Eolie Islands (Aeolian Islands), Metropolitan City of Messina, Sicily, Italy


Locality type:Crater
Classification
Species:Cossaite
Formula:(Mg0.5,◻)Al6(SO4)6(HSO4)F6 · 36H2O
Comments:As white, vitreous, stout prismatic hexagonal crystals, terminated by rhombohedral faces, up to 100 micron long. Found in a pyroclastic breccia, altered by the action of an active fumarole (temperatures around 350°C) along the crater rim, in associatio with thermessaite, vlodatsevite, sassolite, and salammoniac.
