Quantitative paleoenvironmental and paleoclimatic reconstruction using paleosols
ND Sheldon, NJ Tabor - Earth-science reviews, 2009 - Elsevier
Paleosols (fossil soils) are preserved throughout the geologic record in depositional settings
ranging from alluvial systems to between basalt flows. Until recently, paleosols were studied …

Paleosols as indicators of paleoenvironment and paleoclimate
Paleosols are ancient soils that have been incorporated into the geological record. Soils
form in response to interactions among the lithosphere, hydrosphere, biosphere, and …

Fe-Mn concretions and nodules formation in redoximorphic soils and their role on soil phosphorus dynamics: Current knowledge and gaps
Over the last few years, phosphorus (P) has attracted the global interest because it is finite
and non-renewable resource. However, some aspects of P dynamics in soils are still unclear …
