Sillar
From Freepedia
Image:Aqp sillar.jpg Sillar is a whitish volcanic stone from which many colonial buildings in the city of Arequipa, Peru, are made from. A fine example are the Arcs of the "Mirador of Yanahuara" in Arequipa, from which the entire city can be appreciated.
The stone, a vapour-phase crystallized tuff produced by the now-extinct Chachani volcano during the Pleistocene era, was named by the geologist Clarence Fenner in 1948.
