• Allanpringite - Wikipedia

    en.wikipedia.org/wiki/Allanpringite Allanpringite is a phosphate mineral named after Australian mineralogist Allan Pring, South Australian Museum. Allanpringite is a Fe 3+ 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.
