Description Clinoclase etc

Plumbago station, South Australia, Australia

Photographed with permission from the collection of John Chivers

The tiny dark-green rosettes in this image, running in a rough left-to-right direction, are of the rare copper arsenate mineral Clinoclase. They are no more than 3mm across. This image was taken at an incredibly short distance and shows details not visible to the naked eye! I suspect it probably pushes the technical boundaries of my digital camera and I’m pleased with this result, especially with no image stabilization or tripod…

Crystals of Clinoclase can be thin and tabular, or form fibrous rosettes such as these. The other blue and green minerals in this image are also obscure copper minerals.

Commoner copper minerals such as Malachite and Azurite are easily found in South Australia, but up to forty different copper minerals, many of them extremely rare and of interest to specialist collectors, have been found at Plumbago Station.

From what I've heard, the Dome Rock area had some magnificent clinoclase at one point...

Also, another great shot.

Thank you! My camera is the cheapest one available with the shortest closeup/macro focal distance I think...it helps a lot.

How do you know that this is Clinoclase and not one of the other copper minerals?

The greenish-blue portions look very similar to Rosasite.

I just have John's word for it.

Mineral labels locally are a toss up in terms of accuracy - especially for the rarer minerals. Though even some of the not-so-rare ones I've seen lately aren't exactly accurate. Which sort of makes me wonder who's doing the actual mineral identification, because it doesn't always appear to be someone with a knowledgeable background.

I'm happy to trust John since he has the equipment and the resources to sit and pore over his specimens all day, and is actually specialising in these copper minerals and would be pricing them according to whats on them.
