Click here for a list of articles that are not under construction but have had at least their first drafts finished.

This article is a place holder and needs someone to take it in hand and finish the first draft. If you would like to take this article in hand, leave a reply message below or contact Rock Currier via private message by clicking on the PM button next to my name at the top of the article.

Can you help make this a better article? What good localities have we missed? Can you supply pictures of better specimens than those we show here? Can you give us more and better information about the specimens from these localities? Can you supply better geological or historical information on these localities?

Below are some preliminary notes I have made about Agrinierite. This entry and thread has been made as a place holder for information that you will hopefully contribute about Agrinierite. It should be in no way be thought of as a claim I have staked out to write about this mineral, and in fact is an invitation for someone to step forward and create the article about this mineral. If you are so inclined and have questions about the format that such an article should have, go the The welcome topic at the top of the Best Minerals forum and read what has been posted there. Also take a look at some of the more mature articles that have already been written like Rhodochrosite, Adamite, Millerite etc.

Agrinierite(K2CaSr)U3O10 4H20 Orthorhombic
Agrinierite, Margnac Mine, Compreignac, Limousin, France 3mm specimen

Margnac. Found as minute tabular orange orthorhombic crystals with a pseudo-hexagonal section from Margnac. They are found in small cavities in “gummite” associated with becquerelite, billietite, schoepite, compreignacite and most abundantly rameauite. This mineral is a hydrous potassium, calcium, strontium uranite and it is likely very fluorescent and soluble. If you have a specimen of this material you are advised not to wash it, protect it from dust and keep it in a well sealed container.

This stuff is NOT soluble in water.

Peter, you certainly know more about chemistry than I, but I was taught and experience has shown that hydrated potassium minerals are generally quite soluble. What is its solubility any way? 10 to the minus? I could certainly profit by knowing why this one is not. I would like to include this in the article.
