文摘
- •
Brines involved in Proterozoic U deposits (Athabasca, Canada) are targeted.
- •
Halogens (Cl, Br, I) indicate a subaerial evaporation of seawater origin for brines.
- •
Brines acquired excess noble gases (Ar, Kr, Xe) by interaction with clastic sediments.
- •
Interaction with basement-derived fluid or organic matter is unlikely.
