Illitization of smectite as biomineralogical process

, 2020
The analyzed data of 3D structure investigation for the most low-temperature illite indicate that in smectite illitization at least two mechanisms can be involved, from which one is associated with biota activity and doesn't require temperature ...

Trioctahedral Smectite and Interstratified Chlorite/Smectite in Jurassic Strata of the Connecticut Valley

Clays and Clay Minerals, 1981
AbstractTrioctahedral smectite and regularly interstratified chlorite/smectite in strata of the East Berlin Formation of the Connecticut Valley are largely restricted to black shale and gray mudstone deposited in alkaline, perennial lakes. The precursor of the mixed-layer clay appears to have been a smectite.

Radiation-Stability of Smectite

Environmental Science & Technology, 2008
The safety assessment of geological repositories for high-level nuclear waste and spent nuclear fuel requires an understanding of the response of materials to high temperatures and intense radiation fields. Clays, such as smectite, have been proposed as backfill material around waste packages, but their response to intense radiation from short-lived ...

Adsorption of Atrazine on Smectites

Soil Science Society of America Journal, 1992
Abstract Smectites may strongly influence the fate of pesticides in soils due to their large surface area and abundance in agricultural soils. This research was undertaken to determine the effects of smectite properties on the affinity of smectitic clays for atrazine (2‐chloro‐4‐ethylamino‐6‐isopropylamino‐1, 3, 5

Interaction of Rimsulfuron with Smectites

Clays and Clay Minerals, 1997
AbstractThe adsorption of the sulfonylurea herbicide rimsulfuron, [N-((4,6-dimethoxypyrimidin-2-yl)aminocarbonyl)-3-(ethylsulfonyl)-2-pyridinesulfonamide], on clay minerals with different saturating cations was studied. Three smectites with different lattice charge distribution (hectorite, montmorillonite and nontronite) were selected and made ...

Smectite Interactions with Flavomononucleotide

Clays and Clay Minerals, 1984
AbstractAdsorption isotherms and UV-visible and Mössbauer spectroscopic data point to specific interactions between flavomononucleotide (FMN) and Fe3+-smectite. The maximum amount of FMN adsorption was 0.3 mmole/g of Fe3+-smectite giving a 1:1 molar proportion of Fe3+ and FMN.
