Plio-Pleistocene paleosols: Loess-paleosol sequence studied in the Beregovoye section, the Crimean Peninsula

CATENA, 2019
The loess-paleosol sequence exposed in the Beregovoye section (southwest of the Crimean Peninsula) has been thoroughly studied. Detailed analysis of the paleosol morphology, physical properties and chemical composition, micromorphology and other ...

Geochemistry of a Paleosol Horizon at the Base of the Sausar Group, Central India: Implications on Atmospheric Conditions at the Archean–Paleoproterozoic Boundary

Geoscience Frontiers, 2016
A paleosol horizon is described from the contact of the Sausar Group (∼2400 Ma) and its basement (Tirodi Gneiss; >2500 Ma) in Central India. Physical evidence of pedogenesis is marked by the development of stress corrosion cracks, soil peds, corestone ...

A paleosol record of the evolution of Cr redox cycling and evidence for an increase in atmospheric oxygen during the Neoproterozoic

Geobiology, 2019
Atmospheric oxygen levels control the oxidative side of key biogeochemical cycles and place limits on the development of high‐energy metabolisms. Understanding Earth's oxygenation is thus critical to developing a clearer picture of Earth's long‐term ...

A Tianshan Mountains loess-paleosol sequence indicates anti-phase climatic variations in arid central Asia and in East Asia

Earth and Planetary Science Letters, 2018
Paleoclimatic changes in arid central Asia (ACA), one of the largest arid regions in the world, are complex and the nature of these changes on orbital cycles remains unclear.

Morphology and micromorphology of the loess-paleosol sequences in the south of the East European plain (MIS 1–MIS 17)

CATENA, 2018
The micro- and macromorphological studies performed on the loess-soil sequences in the south of the East European Plain permitted to identify and describe the type of soil-formation processes that took part in the development of interstadial and ...

Paleoenvironmental and paleoclimatic interpretation of the Late Cretaceous Marília Formation (Brazil) based on paleosol geochemistry

CATENA, 2019
The Late Cretaceous Marilia Formation located in the central-southern portion of Brazil is characterized by a succession of sandstones, conglomerates, and paleosols.
