Sedimentary Iron Deposits, Evaporites and Phosphorites State of the Art Report
Iron formations, evaporites, and phosphorites are economically important chemical sedimentary rocks developed in basins which span a very large fraction of geologic time. Since they are chemical precipitates, they must reflect the character of the body of water from which they were formed. Our group attempted to determine whether evolutionary changes in the biosphere could be inferred from the stratigraphic record of these sediment types.
