“Swelling Chlorite” [PDF]

open access: yesGéotechnique, 1950
Synopsis On examination, two samples of clay from Keuper marls have been found to contain a chloritic mineral showing a limited c-axis expansion on glycerol treatment. One of these samples gives the same (001) spacing as montmorillonoids when treated with glycerol, and a heating test is necemary to make the distinction.

Mechanism of chlorite degradation to chloride and dioxygen by the enzyme chlorite dismutase

open access: yesArchives of Biochemistry and Biophysics, 2015
Heme b containing chlorite dismutase (Cld) catalyses the conversion of chlorite to chloride and dioxygen which includes an unusual OO bond formation. This review summarizes our knowledge about the interaction of chlorite with heme enzymes and introduces the biological role, phylogeny and structure of functional chlorite dismutases with differences in ...

The formation mechanism of authigenic chlorite in tight sandstone and its effect on tight oil adsorption during hydrocarbon filling

open access: yesOil & Gas Science and Technology, 2021
Authigenic chlorite, which is frequently found in sandstone, has a controlling effect on the reservoirs in which tight oil is adsorbed during hydrocarbon filling. In this study, the content, occurrence state, timing, mechanism and influence of authigenic
