Weathering microenvironments on feldspar surfaces: implications for understanding fluid-mineral reactions in soils [PDF]

open access: yes, 2008
The mechanisms by which coatings develop on weathered grain surfaces, and their potential impact on rates of fluid-mineral interaction, have been investigated by examining feldspars from a 1.1 ky old soil in the Glen Feshie chronosequence, Scottish ...

Rock-eating mycorrhizas: their role in plant nutrition and biogeochemical cycles [PDF]

open access: yes, 2008
A decade ago, tunnels inside mineral grains were found that were likely formed by hyphae of ectomycorrhizal (EcM) fungi. This observation implied that EcM fungi can dissolve mineral grains. The observation raised several questions on the ecology of these

Mineral Weathering and Element Migration in Granite Weathering Pits (Gnammas): A Case Study in Eastern China

open access: yes, 2022
This paper investigates weathering pits at three granite sites located on mountain tops, in a former river bed, and on the coastline of an island, respectively, from north to south in eastern China and aims to characterize weathering pit formation in the

Reservoir theory for studying the geochemical evolution of soils [PDF]

open access: yes, 2010
Linking mineral weathering rates measured in the laboratory to those measured at the landscape scale is problematic. In laboratory studies, collections of minerals are exposed to the same weathering environment over a fixed amount of time.

Geochemical Negative Emissions Technologies: Part I. Review

open access: yesFrontiers in Climate, 2022
Over the previous two decades, a diverse array of geochemical negative emissions technologies (NETs) have been proposed, which use alkaline minerals for removing and permanently storing atmospheric carbon dioxide (CO2).

Strontium as a tracer of weathering processes in a silicate catchment polluted by acid atmospheric inputs, Strengbach, France [PDF]

open access: yes, 2000
This paper determines the weathering and atmospheric contributions of Ca in surface water from a small spruce forested silicate catchment (N–E France) receiving acid atmospheric inputs.

Alkaline Mineral Soil Amendment: A Climate Change ‘Stabilization Wedge’?

open access: yesEnergies, 2019
Extreme climate change due to heat-trapping gases, especially carbon dioxide, necessitates its mitigation. In this context, the carbon dioxide sequestration technology of enhanced weathering has for years been investigated, with a possible implementation

The environmental controls on efficiency of enhanced rock weathering in soils

open access: yesScientific Reports, 2023
Enhanced rock weathering (ERW) in soils is a promising carbon removal technology, but the realistically achievable efficiency, controlled primarily by in situ weathering rates of the applied rocks, is highly uncertain.

The Weathering Microbiome of an Outcropping Granodiorite

open access: yesFrontiers in Microbiology, 2020
Microorganisms have long been recognized for their capacity to catalyze the weathering of silicate minerals. While the vast majority of studies on microbially mediated silicate weathering focus on organotrophic metabolism linked to nutrient acquisition ...
