Cover: Banded iron formations such as those being mined at Mount Tom Price, Western Australia, were deposited over large areas of the ancient seafloor billions of years ago. As sediments that salted directly out of primitive seawater, they captured a chemical record of the evolution of nutrients and biological activity in Earth’s early oceans. See “Phytoplankton contributions to the trace-element composition of Precambrian banded iron formations” by Konhauser et al., p. 941–951.
