A mineral that replicates the shape or form of another material. Pseudomorphs occur in three types:
- Paramorph: a mineral that visually looks like another crystalline structure of the same composition (i.e., Aragonite altering to look like Calcite). This pseudomorph type is also called allomorph.
- Infiltration pseudomorph: a mineral formed by deposition in which the new compound retains the structure and shape of the original (i.e., Petrified wood).
- Incrustation pseudomorph: a mineral formed in the cavity of a previous material whose shape was preserved by a coating from a second mineral (i.e., Fossil).
