Hi Jolyon,As curator of this year's Munich Show special exhibit, I would love to see a mineral art gallery online (actually, I have stated before, elsewhere I would love to see a brick-and-mortar gallery somewhere...Tucson??).As for what should be included?  Well, the guideline for this year's ...

Hi Richard,I was just looking through the article. I am glad someone has made this update. It certainly was due.I have a question and a couple of corrections, though, if I may.This may be something completely obvious to most, but I am in the dark. What is the E-Minerals database you refer to? You ...

Fair enough. Thanks all.

Thanks, Uwe!

However...now the photo seems to be missing...???

I have corrected the ID method in the entry. My apologies. I could swear I did that but obviously not correctly.  I just noticed that one can add the actual analysis...I'll have to do that later.And speaking of jamesonite...the "jamesonite" I had from Mt. Washington turned out to be ...

The specimen was originally labeled "stibnite." Dan Topa of the Natural History Museum - Vienna and I had a little project with feather ores after unexpectedly discovering owyheeite in a sample  from another locality. We then checked other such samples from various locales in BC and ...

As for the minerals, I can add the following:The Sutton-Thompson collection at UBC has the following:Cat 1076 (Horn Silver Mine): Galena, with sphalerite, pyrite, laumontite and chalcopyriteCat 1261 (Horn Silver Mine): Silver, with acanthite, galena, pyrite, bornite, tetrahedrite, quartzCat 1267 ...

Sorry, Uwe. Just realized the coordinates and the BC Minfile references are already there. My recommendation on the locality name stands, though.

Coordinates for the property are:Latitude 049º 03' 25'' Longitude 119º 41' 24'' 

Cawston and Keremeos are both settlements: Keremeos being somewhat more of a center (as an incorporated "village") and Cawston as an "unincorporated community just east of Keremeos). BC-EMPR documents generally refer to the mining property's location relative to Keremeos because of Keremeos' ...

Hi Bob,In cooperation with a scientist at the UBC Museum of Anthropology, I produced a display  at the Pacific Mineral Museum explaining the mineral pigments used to decorated a Haida frog bowl. It was determined that the red colour came from cinnabar (yes, the bowl was used ceremonially for ...

Hi Paul,Metadata that should be in the photo file:Tourmaline glasses. Wire-wrapping design by Naomi Hinds. John White collection; Mark Mauthner photo.Cool to see this circulating around. Makes me wonder how and where.Cheers,Mark Mauthner

Very sad news, indeed. A man worthy of great tribute. RIP, Rock. Mark

What Alex is doing is nothing new... Back in the days before internet, (heck, before personal computers) I had an exercise in school to write letters (grade 6, I think)...so I wrote letters for real. I wrote to mines stating that I wanted to be a geologist and was trying to build up a study ...

Nice, Jolyon! I like that the copyright information floats on the image no matter how far in one zooms. See you in Tucson. Mark

I was always under the impression from having read a few older texts that selenite referred to cleavable masses, alabaster to fine-grained masses, and satin spar to fibrous masses...regardless of color in any case. Since well developed crystals show cleavage, the selenite term was uselessly ...

Most definitely siderite. Siderite occurs in several habits, corroded or not, at Rapid Creek; it is one of the more interesting species at the locality in that regard (variety of habits). I have several self-collected specimens exhibiting exactly the habit shown in your photographs.

Just got back from dinner with friends...and on the way to the car I realized that I forgot the photo caption!! Sorry about that... The information: Cobaltite, actinolite, chalcopyrite, gold on magnetite; 12 cm tall. Merry Widow Mine, Port McNeill, Vancouver Island, British Columbia, Canada. ...

Hi All, Don't get on the social side of the web too often but I just went through this whole thread (it was the Red Rose reference, Maggie ;-) ). Wow! What a great bunch of specimens! It was a pleasant surprise to see among them some "old specimen friends"...and some of my photos. ...

Rudy, I was thinking pretty much along the lines of what John Stolz mentioned; that the ink and appearance of the writing on the note is likely to be that of a ball-point pen (which, according to the history I have read, was invented in the late 1930s, introduced to the Argentine market in the ...

Hi Roy, I tried downloading your poster but ended up with a "forum.php" file, twice. Would love to see the poster. :-) Mark

Hey, congratulations to you both! All the best for this special day and those that follow! Mark

1) It would help if qualifying information would be required with any entry for a species at a given locality. The possibility exists but that data is by far most often not given. So many entries merely say that a species/variety/group simply occurs at the locality. Would it not be more valuable ...

I have seen a few of these sets, but in the one I was able to inspect closely, the agates appeared to have a thin "carnelian" band at the surface that was cleverly carved into. If one looks at the surface of these (at least the one I looked at, which when I last saw it was in the Houston Museum's ...

Hi All, I think the thread finally got to the key point. Rob, you are quite right...areas where material is being hand mined or at least where labor (sorry Rob, "labour") is underpaid to the point that even illicit "specimen mining" is worth the risk are going to be the big producers in the next ...

Hi, We have synthetic malachite in our (GIA) collection that I still find hard to believe are synthetic. They look like typical botryoidal malachite from the Dem. Rep. of Congo! I have yet to find out more about their origin and nature, but I shall endeavor to do so because of this ...

Well said, Alfredo. My limited experience tells me that I see high prices in every kind of venue; low prices too. I was taught that for a given price for a given specimen one can generally, given time, find someone willing to pay 3 times the price, and someone who would not pay a third of it. The ...

I am somewhat familiar with the green quartz gem that is pictured in the G&G article having held it in my hand (and exhibited it at the Denver and Tucson shows). It is now in the Houston Museum of Natural Science and, before that, was in the Jim Houran collection. It is by all accounts natural ...

Just a thought, but one might look up references to "plumose" mica...I have seen (and collected) examples that seem to cover the range from "ball-peen" to "plumose" mica...muscovite, lithian muscovite and lepidolite. Mark

Alan, Is that with the song "All by myself" playing on the door intercom? Mark

Hi Gail, I would love to more about your article. It sounds like just the thing we need. Have you publishe dit yet? Cheers, Mark

A guide for authors is being assembled as we speak (write)...should have it up within a week (after approval from the MinDat heirarchy) :-)

I agree with Rock...localities need to be explicit in what they are. If we do not use "Mountain, Valley, City, etc" then contributors might want to at least put some meaningful description in the Comments box. e.g. for "British Columbia" = "One of 10 provinces in Canada." This is especially ...

I shall be arriving in Tucson on Feb 2nd...driving straight thru from Houston! Fun stuff... Look forward to seeing/meeting you all
