Corrosion residues are relatively insoluable minerals which were once part of the bedrock. They were left behind and concentrated when the bedrock was dissolved. They are the waste products form bacterial processes which utilize manganese and iron in the rock for energy.

On the CCNP Cave Inventory Form, the recorder is asked only to distinguish them by color. There are three color categories on the form: red, brown and yellow. They can usually be found on the floor as fluffy, colored soils (speleosols) but could appear in cracks or vugs or on shelves and ledges. They could even appear as a type of crust or coating. Several colors could be present at a single location. Many caves in the Guadalupes have exceptional examples of corrosion residue.

The CCNP Cave Inventory Form asks the recorder to include the thickness if possible. An estimate of how thick the accumulation is should be included next to the station.
