Allanpringite is a phosphate mineral that was named after the Australian mineralogist, Allan Pring of the South Australian Museum.
Allanpringite is a Fe3+ analogue Al-phosphate mineral wavellite, but it has a different crystal symmetry – monoclinic instead of orthorhombic in wavellite.
It forms needle-like crystals, which are always twinned and form parallel bundles up to about 2 mm long.
They are often found in association with other iron phosphates in abandoned iron mines.
