Yes, it is very green, no incorrect color and yes it does look like fuzzy malachite.
I can get a sample of this specimen analyzed (EDS) as I am sending several other mineral samples up to Kerry Day.
These photos should probably pulled from public gallery until I get results from ...

Sep 2017Re: Britholite - Kyshtym, Urals Region, RussiaReply from Christopher O'Neill in General.Pavel,
Thanks for your reply.
The specimen is 7.5 x 5.5 cm and is only slight radioactive.
The yellow is resinous (gummite-like) and not quartz, however very low radioactivity compared to Ruggles Mine type gummite specimens
There is also minor orange fluorescent mineral in long-wave ...
Sep 2017Britholite - Kyshtym, Urals Region, RussiaPosted by Christopher O'Neill in General.Hello,
I can't identify associated minerals in this particular specimen and there are not many specimens from this region posted in MINDAT that I can visually reference. I suspect the britholite (Ce) is the reddish crystalline but I am puzzled by the resinous-like yellow mineral. This specimen ...

Maybe so with pronunciation, but with a typewriter??
So it is not actually CERITE after all, but Britholite (Ce)?

Jul 2018Cerite var. RESSINGITE - has anyone heard of this??Posted by Christopher O'Neill in Identity Help.Hello all,
I have an old Thompson Fund specimen of CERITE.
Label states variety - RESSINGITE - and I can't find anything pertaining to this varietal name.
I can not find the location of Tenbari, Korea as well, although this may be misspelled.
Any help would be appreciated.

Sep 2016Re: Pennsylvania Mine location helpReply from Christopher O'Neill in General.Jeff / Mark,
I took a closer look and you are right it is yellow / waxy and not white. See attached close-ups below displaying thorite and altered pale yellow thorogummite. Perhaps the green fluorescence is some other alteration mineral or closely intermixed associated mineral. I changed the ...

I would have to send it up to Kerry Day for EDS.
I usually wait until I have about a dozen specimens to be analyzed and then send the lot.

It is also fluorescent pale orange red in short, mid and long wave UV - similar to Brumado, Bahia, Brazil.

Dec 2015Re: Fabricated provenanceReply from Christopher O'Neill in Fakes & Frauds.Hello,
Another scenario. I have already posted a mineral and it has been given a Mindat ID, but now I plan on trimming it, potentially becoming two specimens.
In a sense, the original specimen and it’s Mindat ID no longer exist.
Now I want to post one of the two “new specimens”. ...

Yes that's TAZIN Lake, sorry bout that.
I don't think finding where the deposit actually was will be an easy task.
"Laird Island, Tazin Lake, Saskatchewan, Canada" would do just fine for now.

Laird Island is within Tazan Lake.

Sep 2015Re: Canada Experts (eh?) - Phlogopite, QuebecReply from Christopher O'Neill in Identity Help.Hello,
I will try a bit of the red matrix in vinegar to determine if it is calcite.
The last question: is it common for the apatite to fluoresce that blue in MID-wave from that region?
It is fairly bold (almost resembling typical scheelite in short-wave) and I would think this would have ...
Sep 2015Canada Experts (eh?) - Phlogopite, QuebecPosted by Christopher O'Neill in Identity Help.Hello All,
I am trying to verify a location for this specimen.

I can't find any info on this location but I was hoping the matrix assemblage might give a clue.
The matrix is pale red and can scratch baryte and ...
Mar 2015Re: Harstigen Mine - Caryopilite?Reply from Christopher O'Neill in Identity Help.Hello again,
I sent two crystalline samples for EDS analysis and they both indicate "spessartine". Would you all agree?
Does the Mn / Fe spike indicate something otherwise?
I would like to post this specimen, as it is an interesting assemblage of minerals for this locality.

Is there a way that you cab fix this using the photo ID #'s as a chronological criteria?

The issue I am having is still not solved.

Looks like I don't have permissions for the 'unapproved images' option.
If I am either logged in or out, the first "all" and "newest" photo in my gallery is still the Synadelphite.
I don't understand why you can see the new photos and I can not.

Jan 2015Re: Newly submitted pictures (not approved yet) no longer visibleReply from Christopher O'Neill in Improving Mindat.org.Hello Debbie,
That's strange, because they still do not show up when I view "all" & "newest" photos.
So, you see these as the first two newest submitted photos, with the Synadelphite as the 3rd photo down on my page?

This is still not working for me either.

I understand that they are not approved, but they used to show up in my gallery immediately.
