Volcanic Ash

Fine pyroclastic material (under 2.0 mm diameter; under 0.063 mm diameter for fine ash). The term usually refers to the unconsolidated material but is sometimes also used for its consolidated counterpart, tuff.Neuendorf, K.K.E., Mehl, J.P., Jr., and Jackson, J.A., ed., 2005, Glossary of Geology: American Geological Institute, 799 p.
