A Review of Asbestos Bioweathering by Siderophore-Producing Pseudomonas: A Potential Strategy of Bioremediation

open access: yesMicroorganisms, 2020
Asbestos, silicate minerals present in soil and used for building constructions for many years, are highly toxic due primarily to the presence of high concentrations of the transition metal iron.

Relationship between mineralogy and the physico-chemical properties of till in central Finland [PDF]

open access: yesBulletin of the Geological Society of Finland, 1992
The chemical and physical characteristics of the fine fraction of till were examined in the area of the Raahe-Ladoga metallogenic belt in central Finland. Till, weathered bedrock and rock samples were collected from the area, where element concentrations

Weathering Weather [PDF]

open access: yes, 2020
This chapter argues that paying attention to the weather and its associated processes of geological, biological, and social weathering can destabilize knowledge traditions that insist on dichotomies. Looking to specific histories and current conditions in Guyana and Suriname, this chapter shows how notions of weathering can accommodate a wide range of ...

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 ...

Modeling the evolution of natural cliffs subject to weathering. 1, Limit analysis approach [PDF]

open access: yes, 2011
Retrogressive landsliding evolution of natural slopes subjected to weathering has been modeled by assuming Mohr-Coulomb material behavior and by using an analytical method.

Coevolution of Weathering Front and Water Table

open access: yesGeophysical Research Letters, 2021
Water is known to play an essential role in initiating and maintaining subsurface weathering reactions. However, the interaction between the weathering front and the water table is unclear and under intense debate.

Elemental data for Gonghai Lake sediments show significant effects of human activities on weathering processes after 1550 CE

open access: yesFrontiers in Earth Science, 2023
The international Anthropocene Working Group has recognized the mid-20th centrury (ca. 1950 CE) as the onset of the Anthropocene, but human activities in China altered the land cover and influenced weathering processes much earlier.

Living Lithic and Sublithic Bacterial Communities in Namibian Drylands

open access: yesMicroorganisms, 2021
Dryland xeric conditions exert a deterministic effect on microbial communities, forcing life into refuge niches. Deposited rocks can form a lithic niche for microorganisms in desert regions.

Physical and chemical weathering rates and CO2 consumption in a tropical lateritic environment: the upper Niger basin [PDF]

open access: yes, 1998
The chemical composition of Niger river water measured bimonthly at Bamako Mali. during the period 1990–1992 provides an estimate of present weathering rates in the upper Niger basin.
