Anapaite is a calcium iron phosphate mineral, Ca2Fe2+(PO)4]2·4H2O. It is a mineral that typically occurs in cavities in fossil bearing sedimentary rocks. It is also found in phosphate bearing iron ores.
The spectacular environment that anapaite usually grows in makes it a very popular mineral for collectors. Named after the type locality Anapa, Taman Peninsula, Russia. Some of the best localities are Kertch (Crimea, Ukraine) and Bellaver de Cerdena (Gerona, Spain).
