Santabarbaraite

Phosphate mineral

Santabarbaraite is an amorphous ferric hydroxy phosphate mineral, Italy It also can be found in Victoria, Australia and Lake Baikal This phosphate mineral has a simplified formula Fe3+3(PO4)2(OH)3·5H2O, which is the same formula of another non-amorphous phosphate mineral called allanpringite. Santabarbaraite occurs as pseudomorphic (Fe2+3(PO4)2·8H2O). In the process, monoclinic to form the amorphous santabarbaraite. Pseudomorphism can be seen in Victoria, Australia in Wannon Falls which is originally a well-known locality for vivianite and at Lake Baikal, Siberia where the oxidized santabarbaraite can be seen as a rim surrounding vivianite due to exposure to air.
