Soils and Paleosols [PDF]

open access: yes, 2021
This article reviews the nature of modern and ancient soils. Soils are naturally occurring bodies that mantle most of the land surface of the Earth. They are found on virtually every part of the Earth’s land surface, other than areas covered by water bodies (lakes and rivers), glacial ice, or steep slopes in mountainous terrain.

Lanthanides and Actinides in Humic Acids of Soils and Paleosols of Forest-Steppe Conditions in the Southern Urals [PDF]

open access: yesGeosciences, 2018
This article analyzes the lanthanum, cerium, samarium, europium, terbium, ytterbium, lutetium, uranium, and thorium content in humic acids within soil and paleosol surface horizons from the southern steppe in the Southern Urals.

Environmental Context of Hominin Foot Evolution. [PDF]

open access: yesAm J Biol Anthropol
ABSTRACT Objectives This study investigates the environmental contexts that influenced the evolution of hominin foot morphology, focusing on when, where, and under what conditions key synapomorphies evolved. We test whether shifts in ecological conditions are associated with changes in locomotor function.

Platinum Group Element Traces of CAMP Volcanism Associated With Low‐Latitude Environmental and Biological Disruptions

open access: yesGeophysical Monograph Series, Page 263-304., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Radiocarbon Reveals Modern Carbon Exchange With Topsoil Inorganic Carbon in Drylands. [PDF]

open access: yesGlob Chang Biol
Radiocarbon measurements across drylands reveal that topsoil inorganic carbon carries a measurable modern carbon signature linked to soil pH and organic carbon pools. This modern imprint weakens with increasing aridity and soil depth, indicating reduced exchange with contemporary carbon sources under drier conditions and in deeper soils.

Paleoenvironment Implication of Red Paleosols in a Late Cretaceous Continental Succession, Songliao Basin, NE China

open access: yes, 2021
The limited knowledge of Late Cretaceous terrestrial environments and their response to tectonic events in mid-latitudes can be addressed through continental basin deposits such as paleosols.

Carbon storage and DNA absorption in allophanic soils and paleosols [PDF]

open access: yes, 2014
Andisols and andic paleosols dominated by the nanocrystalline mineral allophane sequester large amounts of carbon (C), attributable mainly to its chemical bonding with charged hydroxyl groups on the surface of allophane together with its physical ...

Reconstruction of the Dead (Grey) Dune evolution along the Curonian Spit, Southeastern Baltic [PDF]

open access: yesBulletin of the Geological Society of Finland, 2013
One of the unique places in Europe in both environmental and cultural terms is the Curonian Spit – a massive sandy barrier separating the Curonian Lagoon from the Baltic Sea. Straddling both the Lithuanian and the Russian parts, the spit is included into
