How were the Earth's solid deposits of iron ore created? Dr. Itay Halevy suggests that, billions of years ago, "green rust" formed in seawater and sank to the ocean bed, becoming an original source of banded iron formations. While this would have been just one means of iron deposition, green rust seems to have delivered a large proportion of iron to our early ocean.
