Allanpringite is a phosphate mineral named after Australian mineralogist Allan Pring 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.
