My guess would certainly be Arsenopyrite as well.....

Photos of those Calcites please.

I would say: Brochantite/Langite series (blueish green.....)

Well done Tom, congrats !Pierre

Glad to hear it Tom, they should make great trading material.......

An airbrush painting by myself -acryl on board- of a brownish-grey Baryte crystal group from the Clara Mine. The crystals are showing numerous phantoms. The largest baryte crystal at the right measures 10 cm. Specimens is in my collection since 1982. http://www.mindat.org/photo-746054.html

Great!! There will be a lot of handshaking going on...... Do you drink good beer ?

The first time in the past 30 years that I am not able to visit the Nautilus Show (health problems...) and then I miss this! I would have loved to shake hands with mr. Mindat himself. Pierre

OK, thanks Debbie, but you will understand my confusion. On my home page, my photo's are in order by "newest first" and are nowhere on page 1, so I scrolled an scrolled and found it: yes as the last photo on the last page (12) Strange would you not think, no wonder I did not see it Thanks ...

Yes guys, I know the problems, why did you think I waited so long before reacting. . Still: the Tsumeb cerussite that my question was all about is nowhere to be seen in "My photos" ? Cheers, Pierre

Ok Ralph, thanks, Pierre

Hi all, I waited a long time before picking this up again, but on the 31st of January, I posted this photo: http://www.mindat.org/photo-663716.html of a great multiple twinned Tsumeb cerussite. It is now nearly end of March and my (good) photo is still nowhere to be seen, not even on my home ...

Same here... What I find baffling is that the language switch allows only to choose between English and Chinese. Whilst I bet there are very few Chinese speaking Mindat members but lots of German, French, Italian, Spanish, Portuguese, Dutch .... Strange !! Pierre

Same problem here.... Pierre

OK David, Thanks for answering, I understand the answer to the first question About the second photo, the Okorusu, celestite one on my Home Page: I noticed that the approval status now has been changed to: Public galleries. Thanks! Pierre

Hi all, on the 31st Januari 2015 I submitted this photo on Mindat: http://www.mindat.org/photo-663716.html since then it was nowhere to be seen, not on "today's photos", not on "yesterday's photos" not on the photos on my home page. What is going on? Mineral and location identity are clearly ...

Hi, I was logged in today, tried to put a new message in and got the same red notice. Worse still, I WAS logged in and when trying to log in again, all of a sudden all the text was in Chinese (I presume). OK I could change the language to English (no other option ??) but at the same time lost my ...

Today I posted this photo on Mindat: http://www.mindat.org/photo-653276.html When looking at the mineral list from this well known location,I was very surprised to notice that celestine is not on list from the Okorusu fluorite mine. Many Okorusu celestite specimens have been offered on some of ...

Hi, makes me think of Pargasite from Pakistan.... http://www.mindat.org/photoscroll.php?frm_id=pscroll&cform_is_valid=1&searchbox=pargasite+from+pakistan&submit_pscroll=Search Cheers, Pierre

It certainly looks like one to me, just had a look at their website (mentioned in the photo caption !!) Should not be allowed on Mindat. Pierre

Huge congratulations Steve, you truly deserve it. Fantastic painting! Pierre

Hi guys, To Anatoly and Uwe: Thanks for the positive response and especially for the confirmation that the specimen indeed comes from the TL. That is what I needed before I could upload the photo's here on Mindat! To Aksel: Thanks for the comment but on further data about the collection ...

Hi all, Recently I acquired an old collection with lots of minerals from Eastern Europe. One of the better specimens is this blue-green Pyrophyllite, dimensions are 18 x 12 x 5 cm! On the label it has: Chromian Pyrophyllite and as location: Berezovsk, Urals Region, Russia. The matrix is an ...

Good on you Jeffrey, I applaud your stand and your humorous signs, also thumbs up for Alfredo when he points out that people actually die by delaying access to real medical treatment while they try "alternative therapies". I find it extremely disturbing that people claim at the same to be ...

Hi Bruce, If I can help with any of my photos on Mindat , I would be glad to. Of course I do not know about the mineral project your student is (was) working on but still: tell him not to hesitate to come in contact with me if ever he needs specific mineral photos . I'll see what I can ...

Hi all: here !s my contribution: want to talk about bent? This is really bent (curled) : Malachite fibrous crystals from the Clara mine, Oberwolfach, Germany. FOV: 2 cm. Self collected in 1999. Photo P.Rondelez

Hi, That is exactly what I thought when looking at photo's 1 and 2: some member of the Feldspar group. Cheers, Pierre

By the way, it is the same photo as "photo id 345705", posted on the 8th November 2010 ! Not yet sold, so need a bit more boosting? Pierre

Debbie, have you read the text underneath? All that is missing is the price! This is blatant commerce and not conform to Mindat rules. All the best, Pierre

Wow, great new option, thanks a lot Jolyon !! Pierre

A friend/collector of mine bought, some years ago,in Southern France a very large, very old French mineral/fossil collection. I visited him 2 days ago and he showed me boxes and boxes full of these dark-honey coloured, tabular, rather beautiful baryte crystals from St.Laurent-du-Pape. The ...

Hi Reiner, That must surely be an error! Pierre

Hi all, When I uploaded my this photo today: http://www.mindat.org/photo-500482.html I took a look at other dioptase photos from the same locality and came across this one: http://www.mindat.org/photo-23110.html surely this must be a mistake,it looks nothing at all like dioptase although,in ...

Hi all (administrators), I posted this photo some days ago: http://www.mindat.org/photo-500192.html with light green apatite from Otjua Farm, Karibib District, Namibia. Before posting it, I noticed that apatite was not on the location's list so I mentioned that in my caption, thinking that ...

Mario, I could not agree more. Pierre Mario Pauwels Wrote: ------------------------------------------------------- > I was just wondered why it has taken more than > four years to cleaning this mess up. I truly can > not believe that a dealer could have that much > influence to keep ...

OK Branko, Thanks for the good work, Pierre

Yes Mario and all others, Things seem to be moving now (at last), only 7 remaining today of which 2 are probables, the other 5 (amongst which the head photo) are very suspicious. Cheers, Pierre

Yes Lefteris, I agree but so does this: http://www.mindat.org/photo-368061.html Analysis has been done on this specimen and turned out clearly: olmiite......... By the way: olmiite has a very large variety of forms and/or colours, 2 examples ...

Hi Paul, The poldervaartite "head picture" is one of ex-collection W. Israel which we both have known for many years (in my case more than 30 years) as being a very conscientious and fair mineral collector/dealer. But he bought these specimens from a South African dealer long before there was ...

Branko, Yesterday morning, there were 13 poldervaartites in the gallery, by evening 8 remained, the rest had been removed to the olmiite gallery. So yes, some changes were made yesterday........... Most of the ones remaining will remain there I am afraid, just look at who posted them on the ...

By the way: In the poldervaartite formula here on Mindat there is no sign of Mn ? http://www.mindat.org/min-3252.html When according to the Handbook of Mineralogy it should be: (Ca;Mn2+)2(SiO3OH)(OH) Clearly something to be looked at, Pierre

Yes indeed Mario, More than3 years later and not much has changed on Mindat concerning Poldervaartite/Olmiite......... Strange to say the least. Pierre

OK Uwe, thanks, let's hope this will once and for all settle the "Poldervaartite-problem" on Mindat, Cheers, Pierre

My thoughts excactly.... What's more: NONE of the poldervaartite specimens on Mindat have been analyzed! Most of them are from "older collections" from before the mistake was known, some of the specimens are really here on Mindat to sell/promote them with as caption 100% ...

Lefteris, You mention: The photo shows typical habit of one of the original finds of Poldervaartite in fact I have seen many, many similar olmiites from very recent finds in N'Chwaning II and II. I have some very good ones, just like the POTD-photo in my collection, they all come from ...

Lefteris, I did look at the other thread in which you mention: The photo shows typical habit of one of the original finds of Poldervaartite in fact I have seen many, many similar olmiites from very recent finds in N'Chwaning II and II. I have some very good ones, just like the POTD-photo in my ...

Hi all, To start with: great photo by one of the greatest minerals photographers. http://www.mindat.org/photo-398139.html BUT: Is this already forgotten: http://www.mindat.org/mesg-7-104499.html. In which is stated that most probably 99 % (if not all) photographs on Mindat of Poldervaartites ...

Thanks again Debbie, but still the question remains: the steep slopes, clearly visible on the topo-map extend well beyond Farm Bergsig, to the East on Farm Brabant and to the West on Farm Erongorus, and as there are no border markers on the terrain (steep slopes) how can the small miners know on ...

Hi Debbie, Thanks for the map, that clarifies the Omaruru / Karibib question. As for the Hohenstein: is it so that this mountain starts on the near plateau above the steep slopes and is thus only the peak called Hohenstein, or are the slopes the bottom part of the same mountain ...

Hi all, I am confused and hope some Namibia "specialists" here can shed light on the matter. I recently acquired a beautiful specimen labeled "Goshenite on Tourmaline, Hohenstein,Erongo Mts,Karibib District, Namibia. I photographed it : http://www.mindat.org/photos/0052971001353757525.jpg ...
