Lithified ash
WebBecause reefs are formed already lithified, they do not undergo compaction as most sediments. Thus, the porosity may be preserved. However, porosity is only likely to be … WebAsh is considered to be pyroclastic because it is a fine dust made up of volcanic rock. One of the most spectacular forms of pyroclastic deposit are the ignimbrites, deposits formed by the high-temperature gas-and-ash mix of a pyroclastic flow event. Classification Figure 2.
