Paleoclimatic Significance of Chemical Weathering in Loess-Derived Paleosols of Subarctic Central Alaska [PDF]

, 2008
Chemical weathering in soils has not been studied extensively in high-latitude regions. Loess sequences with modern soils and paleosols are present in much of subarctic Alaska, and allow an assessment of present and past chemical weathering.

Exceptional preservation informs the paleobiology of tapinocephalid dinocephalians

The Anatomical Record, EarlyView.
Abstract The tapinocephalid dinocephalian Moschops is one of the most iconic taxa of the middle Permian, yet its paleobiology remains one of the least well‐known. Here, we address some aspects of paleoneurology and paleobiology of Moschops using CT scanning of four well preserved skulls from the upper Abrahamskraal Formation of South Africa. Two of the

Investigating Pompeii Subsoil Using Geomatics and Geophysics Merged Analyses

Archaeological Prospection, EarlyView.
ABSTRACT The archaeological site of Pompeii represents an exceptional context for the application of non‐invasive and integrated investigation methods aimed at enhancing the understanding of both exposed and buried remains. This study presents the results of multidisciplinary research conducted in the Palestra Grande site, a large and strategically ...

The German Soil Systematics and the Rationale Behind Its Revision

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background The German Soil Systematics is a pedogenetic classification based on the morphological expressions of pedogenic processes and has been developed over several stages since 1952. The system has successfully been in use for soil classification and soil survey for almost 70 years.

Carbon isotope geochemistry of organic matter in volcanic paleosols constrains paleo‐environmental variations

Journal of Quaternary Science, EarlyView.
ABSTRACT The Fiorano quarry paleosol developed within the Colli Albani volcanic district (Italy) in the time interval bracketed by the deposition of the Pozzolanelle pyroclastic‐flow unit (365 ± 4 ka) and the emplacement of the Capo di Bove lava flow (277 ± 2 ka).

Late Pleistocene to Holocene environmental changes from δ13C determinations in soils at Teotihuacan, Mexico [PDF]

Geofísica Internacional, 2006
Stable carbon isotopic signature (δ13C) of soil organic matter (SOM) is used as a high-spatial resolution tool to infer environmental changes during late Pleistocene to Present in the Teotihuacan valley, Mexico.

Climate‐modulated accumulation and erosion of sediments in the Rodderberg crater basin for the last 439 ka (East Eifel Volcanic Field, Germany)

Journal of Quaternary Science, EarlyView.
ABSTRACT Glacial/interglacial climate cycles since marine isotope stage (MIS) 12 influenced the discontinuous and 73 m‐long sediment record from the volcanic crater of Rodderberg in the East Eifel Volcanic Field, Germany. High‐resolution grain size and geochemical data have been valued by numerical dating techniques (radiocarbon and luminescence dating,

Reconstructing Precambrian pCO2 and pO2 Using Paleosols

, 2021
Paleosols formed in direct contact with the Earth's atmosphere, so they can record the composition of the atmosphere through weathering processes and products.

Micromorphology of the Late and Middle Pleistocene paleosols of the central East European Plain

Geography, Environment, Sustainability, 2019
In this paper we focused on the micromorphology of the Late and Middle Pleistocene paleosols exposed in twelve loess-paleosol sequences sections in the central part of the East European Plain. Each studied paleosol complex known as Mesin (MIS 5), Kamenka
