Apophyllite and Gyrolite on Prehnite Pseudomorphs after Laumontite. These are all examples of a “Pseudomorph” this is a crystal that grows over the surface of another mineral, in these examples the Prehnite grew over Laumontite. The Laumontite has then dissolved away leaving the hollow crust of Prehnite.
