Beschreibung
Tuff is a pyroclastic igneous rock with a fragmental texture and is often friable (loosely held together). Tuff may be composed of volcanic ash (tiny shards of volcanic glass), pumice fragments (see above), pieces of obsidian (solid volcanic glass without significant vesicles), and relatively dense rock fragments.
