Climate and Tectonic Forcing of Depositional Evolution in the Southern North China Basin Since ∼3 Ma

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Marginal basins provide sensitive yet incomplete records of climate and tectonic forcing, and the southern North China Basin provides an ideal setting to decode these interactions since the late Pliocene. A 135.6‐m borehole sequence, the XiaoQian (XQ) core, recovered from the Fuyang region, was dated using AMS 14C, OSL, and ESR, supplemented ...

Gênese de solos derivados de rochas ultramáficas serpentinizadas no sudoeste de Minas Gerais Genesis of soils formed from ultramafic serpentinized rocks in southwestern Minas Gerais (Brazil)

open access: yesRevista Brasileira de Ciência do Solo, 2006
Os solos derivados de rochas serpentinizadas ou serpentinitos constituem um grupo especial de solos em toda superfície terrestre. De caráter ultramáfico, ou seja, rochas com mais de 70 % de minerais máficos (ferromagnesianos), os serpentinitos apresentam

Low temperature, authigenic illite and carbonates in a mixed dolomite-clastic lagoonal and pedogenic setting, Spanish Central System, Spain [PDF]

open access: yes, 2016
The aim of this study was to further our understanding of the pedogenic and lacustrine modification of clay minerals. Some of these modifications are of special interest because they constitute reverse weathering reactions, rare in surface environments ...

Major Reservoir Regulation Reshapes the Composition and Fate of Particulate Organic Carbon in the Yellow River

open access: yesWater Resources Research, Volume 62, Issue 3, March 2026.
Abstract Reservoir regulation significantly alters the export and flux of terrestrial particulate organic carbon (POC), while also modifying its composition and fate within fluvial systems. However, the effects of different regulatory regimes on riverine POC persistence and transformation remains uncertain.

Weathering intensity and trace elements (Ni, Sr, Zn, and Cr) distribution in Vertisols developed on basalt in a semiarid environment: agronomic implications

open access: yesFrontiers in Soil Science
Chemical weathering, a major geomorphic process, controls soil formation and evolution at the Earth’s surface and is strongly influenced by prevailing environmental conditions.

Using [delta] ph as a geochemical index of illite neoformation in saprolite [PDF]

open access: yes, 2008
Sal pH is routinely measured for agronomic purposes. When the difference between KCI pH and H2O pH, or ApH, yields positive values, it is used by soil scientists as a classification criterion for identifying anionic subgroups according to the Soil ...

Recent records of steppe species in Belarus, first indications of a steppe species invasion? [PDF]

open access: yes, 2011
Belarus is situated at a crossroad of natural borders of species distributions: the NE part is situated in a taiga zone, whereas the other part of terrain is in the European forest zone. The distance of Belarus to the steppe zone is about 330 kilometers.

Upbuilding pedogenesis in multisequal tephra-derived soils in the Waikato Region [PDF]

open access: yes, 2000
Soil formation is classically regarded as a 'topdown' process whereby soil thickness, horizonation and vertical anisotropy increase steadily (not necessarily linearly) over time.
