WebAbstract. The existence of Precambrian paleosols has been confirmed in the Elliot Lake district of Canada. However, the lithified weathering products exhibit substantial modification due to diagnesis and lowgrade metamorphism. There is considerable chemical and mineralogical similarity among paleosols derived from different source rocks. Rye & Holland (1998) laid out five criteria for identifying a paleosol. While this was prompted by the need for more stringent identification of Precambrian paleosols, it is applicable to paleosols of any age. The criteria are: • Formed in situ on bedrock, • soft-sediment deformation at the top of the profile, and oldest living primordial dwarf
