Optimization of Parsimonious and Synchronized Discharge and Dissolved Organic Carbon Models Across Catchment Scales

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract The production, transport, loss, and export of dissolved organic carbon (DOC) are closely connected with hydrometeorological drivers. While terrestrial production depends on biogeochemical variables like soil moisture, air temperature, and the contact area between water and organic matter sources, export is determined by water availability and

Quantitative Assessment of Peridotite Tectonomagmatic Affinities Using Compositional Data Analysis and Explainable Machine Learning

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Peridotites record the compositional evolution of the lithospheric and asthenospheric mantle across plume‐related lithospheres, convergent margins, and rift‐related volcanic environments; however, their tectonomagmatic affinities are commonly difficult to resolve using traditional low‐dimensional geochemical discrimination diagrams.

A >300 Myr Long‐Lived Topographic Highland Along the Northern North China Craton Margin Driven by Multistage Continental Convergence

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Topographic highlands commonly develop along convergent plate boundaries through long‐term processes such as subduction and continental collision. However, the pre‐Cenozoic mountain‐building history of deep‐time orogenic systems in northeastern Pangaea remains poorly constrained due to later tectonic overprinting and denudation.

Origin and evolution of the Amazonian craton [PDF]

The Amazonian craton appears to be formed and modifed by processes much like those of the better-known Precambrian cratons, but the major events did not always follow conventional sequences nor did they occur synchronously with those of other cratons ...

A normalised seawater strontium isotope curve: possible implications for Neoproterozoic-Cambrian weathering rates and the further oxygenation of the Earth [PDF]

, 2007
The strontium isotope composition of seawater is strongly influenced on geological time scales by changes in the rates of continental weathering relative to ocean crust alteration.

Microbially Mediated Intracellular Barite Mineralization: Evidence From an Early Ediacaran Microfossil in the Doushantuo Formation of South China

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Barite serves as a key proxy for reconstructing paleo‐oceanic productivity and chemistry in modern and ancient marine sediments. Although contemporary barite precipitation involves biological mediation, the mechanisms responsible for ancient barite formation remain unclear.

Precambrian glaciations and the evolution of the atmosphere

Annales Geophysicae
Precambrian glaciations appear to be confined to two periods, one in the early Proterozoic between 2.5 and 2 Gyears BP (Before Present) and the other in the late Proterozoic between 1 and 0.57 Gyear BP.

Atmospheric Evolution

, 2017
Earth's atmosphere has evolved as volatile species cycle between the atmosphere, ocean, biomass and the solid Earth. The geochemical, biological and astrophysical processes that control atmospheric evolution are reviewed from an "Earth Systems ...

Lithology, age and structure of early proterozoic greenstone belts, West African shield [PDF]

Lithologic and chemical data have been compiled for belts in the Proterozoic terrane. Available stratigraphic information from geologic maps of these areas indicate that a typical sequence is comprised of predominately mafic lava flows (basalt-andesite ...

Some examples of deep structure of the Archean from geophysics [PDF]

The development of Archean crust remains as one of the significant problems in earth science, and a major unknown concerning Archean terrains is the nature of the deep crust.
