Improving Mindat.orgTsumeb Zincolivenite

26th Sep 2019 03:58 UTCKevin Conroy Manager

I just noticed that all of the Zincolivenite photos in the Tsumeb gallery appear to be cuprian adamite. Is this right?

Probably and it's impossible to consult the " change log " as this message appear :

Fatal error: Allowed memory size of 157286400 bytes exhausted (tried to allocate 1302528 bytes) in /home/mindat/www/mysql.php on line 369

Seems that the cuprian adamite has been removed from the list too.

Does this mean that all cuprian adamite is zincolivenite now ?

I would be very dubious about calling all Cuprian Adamites, Zincolovenite

I've had a look around the internet, and the cuprian adamite specimens from several localities are zincolivenite. To avoid further confusion I would suggest that all of the photo descriptions for these specimens be amended to reflect the change.

By the way, the volume 12, 2009 Journal of the Russell Society has a couple of fine articles on British zincolivenite localities.

Malcolm Southwood can give insight into the the cuproadamite-zincolivenite species terminology/classification. He's done extensive analyses of these and has an article pending on the subject

There is a very interesting video on YouTube, search for 2019 Tsumeb Conference - Malcom Southwood & Martin Stevko - Debunking Cuproadamite

Thank you Debbie. That's what we needed.

26th Sep 2019 18:29 UTCPaul De Bondt Manager

I don't wanna be a pain but how do we deal with the other cuprian adamite pictures.

26th Sep 2019 22:15 UTCDebbie Woolf Manager

Malcolm's conclusion is what I shall use. I've added the video link to the locentry entries.

I would think that only the cuprian adamite photos from localities where zincolivenite has been proven need to be amended. Cuprian adamite still exists, just not from some places that we thought it did.

For those interested, a paper on this topic by Mal, Martin and Paul will appear in Rocks & Minerals magazine this coming spring.
