Identity HelpUnknown from Miquel Vacas mine

25th Apr 2012 22:28 UTCRon Layton

First, I do not have the capability of taking good pictures with my microscope. I was trimming a specimen of libethenite from the Miguel Vacas mine in Portugal. I noticed some hairlike crystals in a pocket with psedomalachite balls and some kind of iron oxide under the scope. The color of the acicular crystals is the same green as the libethenite. Some of the crystals are bent and would seem flexible to a degree. They remind me of acicular olivenite but they are the wrong color. AT most, the bundles of crystals are 1mm long. Any help?

A mixite-group mineral? Or a pseudomorph?
