Hinsdalite and corkite are rare and very difficult to identify by visual means alone. Most of the brown/black amorphous stuff up there is various oxides and hydroxides of iron and manganese. If you do ...

PostForum: What is it? - Where is it from?   Posted: Jun 30, 2022 16:27   Subject: Re: Linarite
Linarite and caledonite are not that common in the Caldbecks whereas chrysocolla can be found almost anywhere up there so that would always be my first guess unless you have clearly defined crystals.
