Grenville, Titanite, Magnetite, New York Mine, Glamorgan Township, Ontario

Here are some interesting specimens! I'd be totally misrepresenting them if I told you that they are good looking in conventional ways. However, beauty is in the eye of the beholder and these are certainly attractive from a mineralogical standpoint. These specimens show octahedral crystals of magnetite, more or less coated by titanite crystals. The interesting thing is that the titanite appears to be oriented or epitactic on the magnetite. Associated with an amphibole, a mica and, sometimes, what appears to be allanite. Unique Grenville specimens!
