From my Mont Saint-Hilaire collection - peatite-(Y), ramikite-(Y), sabinaite, chabazite-Na, synchysite-Ce), gobbinsite. Not all would show in a single photo.

Just found this interesting old topic and I have to revise my information:

Which is the maximum number of clearly visible minerals on a collectible specimen you know of?

In my personal collection the maximum number is 4 [...]
This specimen from Namibia contains three varieties of quartz (the main crystal is a colourless rock crystal with phantoms of amethyst AND smoky quartz) plus small balls of pale green prehnite and some smaller rhombohedral calcite crystals; so I have a specimen with FIVE different minerals now instead of four ;-)

PostPosted: Apr 27, 2018 18:55    Post subject: Sociable Sulfides  

One aspect of mineral collecting I really enjoy is associations. Nothing seems to be more "sociable" in this area than sulfides. Here's two specimens that clearly show this trait. These are both from the Yaogangxian Mine, China and I plan to post a few photos of sulfide association from other localities.

The first specimen has at least 9 different species - so, here's a challenge - beat that!

Hi Bob,

This topic was already discussed in this thread: Maximum number of minerals on a specimen so I've merged both threads.

Thanks for proposing it again!

Thanks Jordi - I didn't recall this thread - definitely makes sense to combine them.

I should have added something to the effect that the various species on a specimen should be visible - but no big deal. it is an interesting topic.

thanks again,
kerr, bob kerr

'Visible' is a good criteria, as the most I can think of are about 5000 (so far) - with a photo of the whole planet ;-)

Bob, I like the idea of 'sociable sulphides' I scrolled down your first three images and came to the fourth, without looking at the description first, and thought "That looks like Trepĉa!". Did you collect them yourself? Mine came from when I had a student placement at the mine in the summer of 1959. After retiring I wrote an article about them (not in an academic journal) and during its preparation was in touch with Prof Hyseni. Do you know about the book "Trepça Minerals Atlas" by Prof Bedri Durmishaj, Prof Sylejman Hyseni and Mr Ferat Shala, publ Mitrovicë, 2011

Peter - I have not seen this book but it looks like a must have - I assume there is an English version??

self collected?? I wish. would love to see what you have - please post.

For the past two Tucson shows a young guy from Kosovo, Enis Hajdini (hajdinienis at gmail dot com), has been in a room at the Riverpark Inn (Pueblo Gem and Mineral Show). he has had a wonderful selection of Trepca specimens at quite reasonable prices - and even more reasonable towards the end of the show.

it is definitely worth visiting his room. here's another specimen I got from him - resembling a bird's nest.

Where does one get this book? Putting it into a search engine, I didn't see anyone selling it.

Peter and Bob (and others) I am obtaining for you the details of where to get the book together with cost (I didn't have to purchase mine). I can give you the ISBN:- 978-9951-466-76-9. I will get back to this thread as soon as I have had a reply from Kosovo.

Thanks. Points out the problems with Internet search engines - as I'm sure somewhere it is on the internet, but some rare / arcane search terms do NOT come up with a response. One has to know where on the internet to go first and then search within it...... thanks again. I can't own every beautiful mineral, so I spend a lot of money on good books on minerals - mostly ones focused on areas of World importance plus those lesser-known locations that are of special interest to me.

If you want to include a link you can do so by entering it in the following form:

www(dot)address(dot)com(slash)pagename(dot)html

That way the anti-spam filter will not filter it out. The forum moderators can then edit the link so that it works like a normal one.
