Chlorite removal with granular activated carbon

open access: yes, 2005
Chlorite (ClO2-) is the dominant degradation by-product coming from chlorine dioxide reactions. Compliance to the maximum concentration of 200 μg/l, established by new Italian regulations for drinking water (D. Lgs.

Porosity Preservation in Deeply Buried (8500 m) Jurassic Calcareous Mudstones of the Vienna Basin (Austria)

open access: yesTerra Nova, Volume 38, Issue 5, Page 306-313, October 2026.
ABSTRACT Significant porosity of more than 5% was found at depths of more than 8500 m in poorly sorted, calcareous mudstones of the Malmian Mikulov Formation. These overpressured rocks are the main hydrocarbon source rock in the Vienna Basin. Core samples from present‐day depths of 8150 m to 8550 m were analysed using X‐ray diffraction and scanning ...

Chlorite removal with ferrous ions

open access: yes, 2005
Effective use of chlorine dioxide as an alternative disinfectant in water treatment may require removal of the byproduct chlorite ion (ClO2-). The goal of this research was to investigate the use of ferrous iron (Fe2+) for the chemical reduction of ClO2-

Chlorite polytype geothermometry

open access: yes, 1993
--Since the initial studies of chlorite polytypes, it has been suggested that the stability of the various polytypes may be a function of the temperature at which the mineral formed; however, few studies have been performed in which polytypes of chlorite

Multi‐proxy sequence stratigraphy of a mixed carbonate–siliciclastic shelf across the Jurassic–Cretaceous transition

open access: yesThe Depositional Record, Volume 12, Issue 4, September 2026.
An integrated facies, MS and XRF‐based approach applied to the Tithonian–Berriasian Sidi Khalif Formation (central Tunisia) resolves five Tithonian and eight Berriasian third‐order sequences, showing how mixed carbonate–siliciclastic shelves record coupled eustatic, climatic and tectonic controls and providing a transferable template for similar mud ...

Detrital zircon ages, Lu‐Hf isotopes of zircon grains, Sr‐Nd isotopes on whole rock and geochemistry of Campanian turbidites in the Eastern Pontides (NE Türkiye): A provenance assessment and Gondwana records

open access: yesThe Depositional Record, Volume 12, Issue 4, September 2026.
These findings confirm that the Campanian‐aged Bozbent Member turbiditic sequence in the Eastern Pontides was deposited in an extensional fore‐arc basin and therefore exhibits the petrographic and geochemical characteristics of passive margin sandstones.

Mechanical Properties and Fracture Behaviour of New Zealand Nephrite Jade (Pounamu): Implications for Fibre‐Toughening Mechanisms in Amphibole Monomineralic Rocks

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.
Results of the first comprehensive quantitative analysis of the mechanical properties of New Zealand nephrite jade (pounamu), including hardness, Young's modulus, fracture toughness and notched flexural strength are reported for seven samples. These samples of exceptional quality were pre‐selected by experienced Māori carvers through a ranking process.
