Rates of iron oxide enrichment of soils on a segmented alluvial fan in southern Tunisia are examined. Mineral magnetic and chemical characteristics of soils developed on 2 dated relict segments and on contemporary alluvium suggest that the rate of Fe-oxide enrichment was more rapid in the Holocene than in the Pleistocene. Thus, Fe-oxide concentration may be used to determine an ordinal chronology of some geomorphological surfaces in drylands, but rates of enrichment cannot be assumed to be uniform over time
