The name apophyllite refers to a specific group of PHYLLOSILICATES , a class of minerals that also includes the micsa. Originally, the group name referred to a specific mineral, but was redefined in 1978 to stand for a class of minerals of similar chemical makeup that comprise a  series, and includes the members apophyllite-(KF), apophyllite-(KOH), and apophyllite-(NaF). The name apophyllite is derived from the greek  €πŒΦυλλίςο apophylliso, meaning "it flakes off", a reference to this class's tendency to flake apart when heated, due to water loss. These minerals are typically found as secondary minerals in holes in basalt  or other igneous rocks. They can also be called "fisheye stone". A recent change in the nomenclature system used for this group was approved by the Int mineralogical association removing the prefixes from the species names and using suffixes to designate the species.
