The Venue

Ischia is a volcanic island in the Tyrrhenian Sea. It lies at the northern end of the Gulf of Naples, about 30 kilometres (19 miles) from the city of Naples. It is the largest of the Phlegrean Islands. Ischia is the name of the main comune of the island. The other comuni of the island are Barano d’Ischia, Casamicciola Terme, Forio, Lacco Ameno, and Serrara Fontana.

Ischia’s main industry is tourism, centering on thermal spas that cater mostly to European (especially German) and Asian tourists eager to enjoy the fruits of the island’s natural volcanic activity, its hot springs, and its volcanic mud.

Scientific Content

  • The conference will consist of a variety of oral and poster sessions, with two session chairs for each, chosen to provide international representation.
  • Chairs of individual sessions will be tasked with advertising and filling the respective sessions.
  • Poster sessions will be held in the afternoons, accompanied by wine and cheese.
  • We propose awards for the top student oral and poster presentations.

Field Trips

  • One mid-week field trip will be organized on the island of Ischia, to focus on clay and zeolite mineralogy, geology, and the history of the island.
  • A several-day post-meeting field trip will be organized to visit zeolite and clay mineral deposits in southern Italy

Scientific Program

Possible sessions/symposia at Zeolite ’22 include:

  • Crystal structures of natural zeolites
  • Zeolite formation and occurrences
  • Environmental applications of natural zeolites
  • Pharmaceutical applications of natural zeolites
