Note about Stone "Tuff"
Tuff (Latin: tofus or tophus) is a magmatic rock, in particular
is the most widespread pyroclastic rocks. Although the name
"tuff" should be strictly reserved for formations
of volcanic origin, it is used to indicate different rocks,
united by the fact of being light, medium hard and easy to work.
In particular, in some Italian regions devoid of tuffaceous
volcanic deposits called tufa limestone is porous (eg, the tuff
tuffs - understood as different varieties of tufa stone - is
formed mostly of lapilli in size between 2 mm and 30 mm, which
is emitted during a volcanic eruption. Tufiti are indicated
by the name of those rocks formed by volcanic material debris,
possibly also associated with sea shells.
The structure is called tuff or Ciner vitroclastica for the
appearance of the glass portion which is finely divided and
The smaller lapilli can sometimes imprison those of larger
size that solidification is realized also through the action
The environment in which they are deposited lapilli can be
extremely variable and, together with the composition of the
rock, determine the characteristics of color, structure and
texture of the tuffs.
