_small.jpg) | Mounted in a plastic miniature box, The light blue micaceous mineral is the Chalcophyllite. The other bluish green mounds are probably the Tyrolite with micro platey crystals of Tyrolite. Spangolite is uncommon and I assume there are some micro crystals present since labeled on the bottom of the case and on Dana's label but I have not looked under a microscope to see what might show up. ex Dana Willson MD collection #300. |
