Looking for info from Margabal minerals I found that autunite/meta-autunite is not listed in the locality.
There are some comments in pictures about uranocircite as the yellow original mineral.
I have analyzed by SEM-EDS some yellow crystals of two specimens (photo attached) and no Ba present at all in results.
Please, could you publish some more info about this uranocircite.

Yes, I know, uranocircite is present in Margabal, but yellow mineral under torbernite
is it uranocircite? I have analyzed yellow parts of metatorbernite specimen.

According to the spectrum, the yellow mineral will be autunite or meta-autunite.
Autunite/meta-autunite often occurs in expitaxial intergrowths with torbernite/metatorbernite.
