Disputed status as mineral species

Thanks for the notes about that -- not something I was aware of. I recall from when I worked in Miami, AZ the 'gemmy chrysocolla' from Inspiration (Live Oak??) was chrys coated with a thin "skin' of clear chalcedony -- so it didn't crumble, dehydrate & didintegrate as most older chrys samples do, sigh.

Formula bogus? x < 1? Expert needed...

The formula given is weird. It uses 2-x in two places (usually the larger expression appears once) and places an upper bound of x at 0.999. I'm pretty sure that's not right, but an expert should check
