Ganophyllite's name came from the Greek words leaf (φύλλον) and luster (γανωμα).^[1] It got its name from Axel Hamberg in 1890. It is a member of Ganophyllite group, among with eggletonite and tamaite. It has a barely detectable potassium radioactivity. The formula includes potassium (K) if it is ganophyllite, eggletonite includes natrium (Na), and tamaite includes calcium (Ca) in their formula.
