A rare kind of mineral which scientists hope could be used to remove toxic metals and radioactive species from the environment played a similar, crucial role early in Earth's history. Research carried ...

Though they may seem rock solid, the ancient sedimentary rocks called iron formations - the world's chief economic source of iron ore - were once dissolved in seawater. How did that iron go from a ...

Iron formations deposited in marine settings during the Precambrian represent large sinks of iron and silica, and have been used to reconstruct environmental conditions at the time of their formation.

How were Earth's solid deposits of iron ore created? One researchers suggests that, billions of years ago, "green rust" formed in seawater and sank to the ocean bed, becoming an original source of ...
