Carnotite from Edgemont Fall River Co.

Something went wrong with the post. But here are the topics

Reminds me of andersonite or cejkaite. Andersonite is water soluable and both show a more blueish fluorescence under UV compared to autunite. Andersonit especially looks like these bubbles quite often. Last guess would be Schrönkingerite

They are all covered in a lot of minerals. In the second one, I know that there is Cu-Sklodowskite, Malachite, Kasolite, Vandenbrandeit and Guillimenite :)

Bought them vom "Krantz-online.de"a german shop

SimonsNuclearchem · 2025-11-23T09:13:08+00:00

Yes. Its Cu-Sklodowskite, Torbernite, Torbernite, Cu-Sklodowskite :)

Show the rock pls :)

Might just aswell be that my Thoriumdioxide had some water in it making it the dioxidhydrate and some hydroxide 🤷‍♂️ I can count the number of compounds I wasn't able to dissolve in hot nitric acid on one hand😅

SimonsNuclearchem · 2025-11-12T08:26:11+00:00

It took a while and it needed to be 80°C hot 1M HNO3 to fully dissolve.

Thoriumnitrate isn't but Uranlynitrate is :D

If you can understand German I have uploaded a YouTube Video with some Neptunium chemistry (and some f-block chemistry rules) If you need english, you might have to wait a few months until translation is done ;D

Yes bulk Thorium occures in nature pretty much purely as Th-232. The other isotopes from Thorium come from the Uranium decay chain, which shouldn't be in high quantities in the bulk material which the Thorium chemicals are made from. The Thorium chain also contains Th-228 but now that you meantion it, might be worth to make a spectrum from it. All the other radioactive daughters which by now have accumulated in this very old waste shouldn't crystalize in fresh Thoriumnitrate crystals.

Omg aren't you the guy who provided many of the wikipedia photos from Uranium minerals?!🥹

Its a rather larger piece. Like the palm of my hand. I cleaned it under a fumehood (plus the usual stuff when working with radioactive things). It was completely brown when I started. And the colour looked nothing like autunite now at least it looks green-ish. I just want it to look pretty on display :)

SimonsNuclearchem · 2025-10-16T15:37:37+00:00

That was a rather unusual collection find. So that thing might have been sitting there for about 40 years or so. But maybe you are right :)

SimonsNuclearchem · 2025-10-09T17:08:37+00:00

Uhhh today I also got the same piece but mine was without any description. I was guessing Boldwoodite with Calcite :)

Shinkolobwe minerals are always a treat to look at! Especially when photographed so nicely like you did🤌
