About Axinite-(Fe)Hide

Formula:
Ca2Fe2+Al2BSi4O15OH
Colour:
Brown, clove-brown, plum blue, pearl gray
Lustre:
Vitreous
Hardness:
6½ - 7
Specific Gravity:
3.25 - 3.28

Member of:
Name:
Originally named Espéce de Schorl by Johann Gottfried Schreiber in 1781. Named Schorl violet and Schorl transparent lenticulaire by Romé de L'Isle in 1785. Named Thumerstein by Abraham Gottlob Werner in 1788, later spelled Thumite. Named Yanolite by Jean Claude de la Métherie in 1792. Named Glasschörl by Blumenberg in 1799 (also glasstein). Named axinit in 1797 by Rene Just Haüy from the Greek αξίνα ("axina") for "axe", in allusion to the common habit of its crystals. Renamed ferroaxinite by Waldemar T. Schaller in 1909 for iron dominance in the formula. Renamed with suffix "-(Fe)" by IMA in 2007.
