Tuff is a soil type described by Tom Stevenson as ‘rocks formed by fractured or water-bound material ejected by volcanic activity. Tuff drains well and is found in Taburno, Campania, in Italy; Balatonfüred-Csopak, Balotonfelvidék and Balatonboglár around Lake Balaton in Hungary; and the Galilee region of Israel, particularly Upper Galilee and the Golan Heights.’

John Szabo (2016, p.249) describes tuff as ‘rock composed of volcanic ash. Once deposited, it compacts and consolidates into a solid, though relatively soft rock, which is easily carved. Not to be confused with tufa, a type of limestone.’
