Abstract

Extractable Fe and Al distributions in surface and buried paleosols suggest that leaching is more pronounced in the older paleosols with a considerable difference in soil-forming environment between Pleistocene interstadial, later Pleistocene, and postglacial paleosols. There is no evidence that the Na-pyrophosphate extractable Fe and Al were affected by degradation of organic matter following burial| however, the data suggest that some amorphous Fe and Al might have been affected by soil water movement over permafrost and by redistribution of preweathered sediments
