Identity HelpAuricalcite vs. Hemimorphite vs. Rosasite

6th Oct 2019 19:18 UTCJakob Sørensen

Hello there,

The following two pictures are of the same specimen from the "Pech Cardou mine" in France: 

I believe the first picture is Auricalcite (see the thin needle-shaped crystals) and the second picture is Hemimorphite? What confuses me, however, is the second picture where the needle-shaped crystals are missing. This part of the specimen also looks like Rosasite in my opinion... All three minerals have been found in the mine, so in theory they could all occur on the same specimen and even mixed together.

To be honest, I am too inexperienced to see the difference between Auricalcite, Hemimorphite and Rosasite on a specimen like this one. Please help me haha. :-D

its quite common to find them together, whitish = hemimorphite and bluish = aurichalcite
