Significance of Precambrian Paleosols

1992
The economic significance of Precambrian paleosols largely lies in their common association with stratabound uranium ore. Their significance to resolution of Earth history depends upon their origin. There are four possible genetic models for known paleosols, i.e., the biologic, abiologic, exhalative, and bolide-impact models. Biologic soil formation is

Micromorphology of Lithified Paleosols

1990
Abstract Lithified paleosols show a variety of microscopic fabrics similar to those of the rocks that enclose them. Sedimentary microfabrics are common in soils and paleosols that were weakly developed or waterlogged. Also preserved in many paleosols are soil microfabrics distinct from those of sedimentary rocks.
