Introducing the soil mineral carbon pump
Microorganisms and minerals both contribute to organic carbon preservation and accumulation in soil. The soil microbial carbon pump describes the microbial processes, but a separate soil mineral carbon pump ne...

Open AccessMineralogical control on methylotrophic methanogenesis and implications for cryptic methane cycling in marine surface sediment
Minerals are widely proposed to protect organic carbon from degradation and thus promote the persistence of organic carbon in soils and sediments, yet a direct link between mineral adsorption and retardation o...

Open AccessCarboxyl-richness controls organic carbon preservation during coprecipitation with iron (oxyhydr)oxides in the natural environment
The coprecipitation of organic carbon with iron minerals is important for its preservation in soils and sediments, but the mechanisms for carbon-iron interactions and thus the controls on organic carbon cyclin...

Open AccessThe importance of non-carbonate mineral weathering as a soil formation mechanism within a karst weathering profile in the SPECTRA Critical Zone Observatory, Guizhou Province, China
Soil degradation, including rocky desertification, of the karst regions in China is severe. Karst landscapes are especially sensitive to soil degradation as carbonate rocks are nutrient-poor and easily eroded....
