Abstract
AbstractMagnetic separations of whole soil and sediment samples from the Maumee River Basin (Ohio) commonly produced small but significant quantities of detrital magnetite. These magnetites were soluble in acid solutions of ammonium oxalate and were also more reactive than a standard magnetite sample of comparable particle size. Differential thermal analyses suggested that the enhanced reactivity of the soil and sediment magnetites may be due to altered grain surfaces. Since detrital magnetite is a common constituent of the sand and silt fractions of many soils and sediments, care should be exercised when evaluating “amorphous” iron data obtained by any of the popular oxalate procedures.
