About IangreyiteHide

Ian E. Grey
Formula:
Ca2Al7(PO4)2(PO3OH)2(OH,F)15 · 8H2O
Crystal System:
Trigonal
Name:
The mineral is named in honour of Dr Ian Edward Grey (b. 1944), formerly Chief Research Scientist at CSIRO Minerals, Melbourne, Australia, for his contributions to mineralogy, crystallography and the minerals-processing industry. Recently, Dr Grey’s expertise was key to solving a number of unique crystal-chemical problems related to alunite-supergroup members such as kolitschite, kintoreite and jarosite as well the structure of perhamite.
Visually similar to several alunite-type minerals (e.g., crandallite, plumbogummite), krásnoite and perhamite.
