Ok now miscellaneous minerals. I walked around and took pictures of pieces that I either didn't remember taking photos of earlier - or that I thought came out poorly. So I am sorry if there are duplicates in this next section. they are not necessarily in any order.

That is the official end of my photo tour of the Smithsonian. I have no other pictures that I think turned out good enough to post (some of the ones I posted I hesitated on as well).

Thanks for looking and for your kind comments

Really great photos, Bob!

Thanks for taking time to share your SI visit. I loved seeing the displays and your comments.

Please post more when you visit other museums and collections.

Cheers!

In https://www.mineral-forum.com/message-board/viewtopic.php?p=24658#24658 simonoff wrote:
...How about some more

I have received several corrections on the Smithsonian labels that I thought I would share. I do not have enough knowledge to agree or disagree with the suggested modifications, but I have been assured that the person making the suggestions is an expert on the minerals of the region.

Concerning the Becquerelite from Mashamba

Here are the edited comments from Paul De Bondt - THANKS PAUL
The Mashamba specimen is uranophane or in the best cases sklodowskite but all the analysed specimens of that type where confirmed uranophane. Becquerelite sits ALWAYS on massive uraninite as it is one of the first alteration products to form. The link that you added shows this very well. The black mineral is pure uraninite. As uraninite, the primairy uranium mineral, was never found in Mashamba, Becquerelite could not occur. If the uraninite was eroded away leaving only silicates and carbonates or like in Mashamba vanadates, the becquerelite would have disolved away too because it's very easily to remobilize.

Concerning the metatorbernite's location
Here are the edited comments from Paul - THANK YOU PAUL:
The torbernite is wrong is for several reasons. The first and most important for a museum is that Shinkolobwe torbernite changes rapidly to metatorbernite and gets light green and opaque in a few days/months and crumbles easily after that. Musonoi torbernite does dehydrate also, but the colour and luster remains. Shinkolobwe torbernite is also not as bright as Musonoi. The crystals cluster tightly together and give a more filled-up crystal cluster while Musonoi gives sharp separated crystals. Shinkolobwe torbernite is found in the phosphate zone and is usually mixed up with curite, saléeite and other yellow stuff, but not always. Heterogenite, the black stain on the matrix of the Smithsonian piece, is typical. In Shinkolobwe, the heterogenite sometimes covers the torbernite but never or very rarely in Musonoi.

Concerning the francevillite
The correct location should be Mounana Mine (Mouana Mine), Franceville, Haut-Ogooué Province, Gabon

Again, I am not claiming that the updated information is definitely correct - I am just passing on the suggestions from someone who knows much more than I.

Concerning image 4262 - 2 fluorite experts have contacted me and said that this is actually from "Weardale, not Cumbria and almost certainly from Boltsburn, which is the only place I've seen throw these odd elongate crystals. Many old specimens just labeled Weardale or Cumbria almost interchangably." - Joan Kureczka with agreement from Martin Gruell

How about some more


I have received several corrections on the Smithsonian labels that I thought I would share. I do not have enough knowledge to agree or disagree with the suggested modifications, but I have been assured that the person making the suggestions is an expert on the minerals of the region.

Concerning the Becquerelite from Mashamba IMG_4384

Here are the edited comments from Paul De Bondt - THANKS PAUL
The Mashamba specimen is uranophane or in the best cases sklodowskite but all the analysed specimens of that type where confirmed uranophane. Becquerelite sits ALWAYS on massive uraninite as it is one of the first alteration products to form. The link that you added shows this very well. The black mineral is pure uraninite. As uraninite, the primairy uranium mineral, was never found in Mashamba, Becquerelite could not occur. If the uraninite was eroded away leaving only silicates and carbonates or like in Mashamba vanadates, the becquerelite would have disolved away too because it's very easily to remobilize.

Concerning the metatorbernite's location IMG_4383
Here are the edited comments from Paul - THANK YOU PAUL:
The torbernite is wrong is for several reasons. The first and most important for a museum is that Shinkolobwe torbernite changes rapidly to metatorbernite and gets light green and opaque in a few days/months and crumbles easily after that. Musonoi torbernite does dehydrate also, but the colour and luster remains. Shinkolobwe torbernite is also not as bright as Musonoi. The crystals cluster tightly together and give a more filled-up crystal cluster while Musonoi gives sharp separated crystals. Shinkolobwe torbernite is found in the phosphate zone and is usually mixed up with curite, saléeite and other yellow stuff, but not always. Heterogenite, the black stain on the matrix of the Smithsonian piece, is typical. In Shinkolobwe, the heterogenite sometimes covers the torbernite but never or very rarely in Musonoi.

Concerning the francevillite (IMG_4380
The correct location should be Mounana Mine (Mouana Mine), Franceville, Haut-Ogooué Province, Gabon

Again, I am not claiming that the updated information is definitely correct - I am just passing on the suggestions from someone who knows much more than I.

Bob


I added the image numbers above - not sure if there is a better way to reference earlier posts - sorry for the confusion

Now from the zeolites case


Concerning IMG_4323. I am told these these are from Chimney Rock Quarry

...Fluorite Case (colors)

Again, this is from someone who has studied English fluorites
I am told that IMG_4551 is Weardale. It's either Heights Mine or White's Level, Middlehope. Would need to see the matrix to tell. Given the probable age of the piece, probably Middlehope. Many of the older pieces labeled Heights were actually from this mine.
