How is wulfenite formed
Did you know?
WebWulfenite is a lead molybdate mineral with the formula Pb Mo O 4. It can be most often found as thin tabular crystals with a bright orange-red to yellow-orange color, sometimes brown, although the color can be highly variable. In its yellow form it is sometimes called 'yellow lead ore'. Web2 mei 2024 · The sequence of crystal formation for these two species varied within the solution environment. In some cases, mimetite formed first, followed by wulfenite. In other examples, the reverse happened. Even more appealing and most often in the majority of the better specimens, the two species were developing crystals at the same time.
