Grenville, Fluoborite, Crystal Lake, Galway Township, Peterborough Co., Ontario

Here is a unique mineral from the Grenville Geological Province! These specimens were treated with weak acid to expose colourless-white fluoborite crystals associated with orange norbergite. For fluorescent enthusiasts, please note that the fluoborite fluoresces a strong creamy white and the norbergite a dull orange under U/V. Unusual!
