WebJul 1, 2004 · In floodplain mudrocks, where the texture of reworked aggregates is lost, the mudrock beds attain a massive and structureless morphology. Such units can be confused with more developed paleosol horizons, and in the present study this process is termed pseudo-pedodestratification. Neglecting or overlooking the presence of the mud … WebTo expand on this work, we sampled a 3-km laterally-continuous floodplain paleosol of the Wasatch formation at Oregon Buttes in the GRB. These 11 paleosol profiles had varying redox conditions but were characterized by geochemical homogeneity with respect to weathering indices and paleoclimate proxies. By resampling a random subset (n=1 thru …
