tuff

Also known as: tuff
Scope note: Tuff is a type of volcanic rock, and is formed from ash that is ejected from certain types of volcano during eruptions. The ash forms beds, which when consolidated (solidified) are called ‘tuff’. Depending on the comparative amounts of ash/volcanic glass/rock fragments in the tuff it is called either crystal-, vitreous-, or lithic-tuff. Tuffs can be formed from either ash-fall (e.g. Mount Pinatubo)or ash-flow (e.g. Vesuvius-Pompeii) eruptions. Tuffs are very fine grained rocks (grains usually no bigger than 2mm in diameter).
