        "http://www.w3.org/2000/01/rdf-schema#comment" : [ "Tuff (from the Italian tufo) is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. Following ejection and deposition, the ash is compacted into a solid rock in a process called consolidation.  Tuff is sometimes called tufa, particularly when used as construction material, although tufa also refers to a quite different rock.  Rock that contains greater than 50% tuff is considered tuffaceous." ] ,
