Hydrated normal phosphate
Specific gravity: 2.81
Colour: Green, greenish-white, milky white, colourless; colourless to light green in transmitted light.
Solubility: Readily soluble in hydrochloric and nitric acids
Anapaite occurs in oolitic iron ore, in the stems of fossil trees and in lacustrine sediments (Webmin, HOM). It also occurs occasionally
in late-stage phosphate mineralisation in granite pegmatites (Mindat).
Associated minerals include fairfieldite,
goethite, vivianite and
siderite (HOM, Mindat).
At the type locality, Zheleznyi Rog, Anapa, Taman Peninsula, Krasnodar Krai, Russia, anapaite occurs in oolitic iron ore, and in the stems of fossil trees, associated with vivianite, siderite, mitridatite, limonite, goethite and calcite (Mindat).
