Abstract

Effects of wind-blown iron and manganese ore dust on the upper part of a sandy beach have been investigated. The fine ore dust was found to reduce the porosity and permeability of the sand by clogging the interstices. The presence of ore dust also greatly increased the rate of heating and cooling of beach sand. Further, ore dust, although of negligible solubility, was found to inhibit the action of aerobic bacteria. This is thought to be due to iron and manganese forming oxidation-reduction combinations in the sand. Ore dust appeared, however, to have no effects on the meiofauna.
