Fluorichterite [ Ca₂(Mg,Fe,Al)₅(Al,Si)₈O₂₂(OH)₂ ] is an inosilicate/amphibole and is found at Wilberforce in Ontario, Canada - the only location it is known to exist. The crystals form in a skarn formation and the alteration it undergoes produces many odd and rare minerals like fluorichterite. Wilberforce is a small settlement near Bancroft, Ontario, a town known as the Mineral Capital of Canada. Wilberforce is a well known locality for these rare minerals.
