Prehnite is usually a translucent, green to yellow, silicate mineral that includes calcium and aluminum.

Stilbite is another silicate made up of calcium and aluminum… and sodium. Stilbite is usually a white to cream colored mineral, and, in this case, for some reason, looks a lot like puffed rice cereal.

There is also some small amounts of black mineral on the specimen. Probably Epidote.
