Extract

Platinum, palladium, gold, and iridium have been determined by radiochemical neutron-activation analysis in three lateritic profiles developed on serpentinized peridotite. In addition, a number of major, minor, and other trace elements have been estimated by conventional chemical, instrumental neutron-activation, and radiochemical methods. The fractionation of the elements as a result of the tropical weathering has been investigated as a function of depth. Each of the profiles L--Guatemala, BNC--New Caledonia, and BIP--Indonesia- has a lower decomposed serpentinite zone and upper zones enriched in iron nl oxides and hydroxides.
