  • Some researchers have found that the uranium conglomerates bearing uraninite have a texture and mineralogical makeup (uraninite, pyrite, molybdenite, and sulfides) one would expect if they were deposited by hydrothermal solutions, indicating that the uranium was deposited deep in the earth, far removed from the atmosphere, similar to what is observed happening in the origin of modern and more recently formed uraninite deposits9 (which obviously occurred in an oxygenic atmosphere).

  • In fact, BIFs from about 2.0 Ga, when the atmosphere was supposedly becoming more oxygenic, look the same as BIFs from earlier pre-Cambrian BIFs19.
