Oxygen Isotopes in Authigenic Clay Minerals: Toward Building a Reliable Salinity Proxy

Geophysical Research Letters, 2020
Most clay minerals in sedimentary environments have traditionally been considered to be of detrital origin, but under certain conditions, authigenic clay minerals can form at low temperature through the transformation of precursor clays or as direct ...

Chemical controls on incipient Mg-silicate crystallisation at 25oC : implications for early and late diagenesis [PDF]

, 2014
Mg-silicate minerals (e.g., stevensite, kerolite, talc, sepiolite) play an important role in the construction of facies models in lacustrine and peri-marine environments because they are sensitive to changes in solution chemistry.

Investigation of Clay Type on Low Salinity Water Flooding Using a Glass Micromodel

Frontiers in Energy Research, 2020
Clay minerals are usually regarded as an important factor affecting the results of low salinity water (LSW) flooding. However, experiments on clay minerals are mainly in qualitative stage, the mechanism of clay minerals has not been studied completely ...

Natural South African iron‐rich sand as a functional catalyst in hybrid photocatalytic wet peroxide oxidation technology for the degradation of methyl orange dye pollutant

The Canadian Journal of Chemical Engineering, EarlyView.
This research explored South African iron‐rich sand (SAIRS) as a natural catalyst for light‐mediated wet peroxide oxidation of methyl orange dye in wastewater and at an optimized of conditions of 3500 mg/L catalyst dose, 6 mM H2O2, and pH 2.5, SAIRS achieved 94% methyl orange degradation within 90 min under visible light.

Towards an understanding of thermodynamic and kinetic controls on the formation of clay minerals from volcanic glass under various environmental conditions [PDF]

, 1996
lmogolite is the kinetically and thermodynamically favoured weathering product from rhyolitic volcanic glass in the soil-forming environment. However, on thermodynamic grounds imogolite would also appear to be the favoured alteration product of rhyolitic

Safety soft sensor development for pilot‐scale ilmenite electric arc furnace using long short‐term memory‐based architecture

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Ilmenite electric arc furnaces (EAFs) are used for smelting titanium‐iron oxide ore at high temperatures generated by electrical arcs to produce titanium slag and pig iron. As these units are pushed to their limits, ensuring safe and reliable operation becomes challenging.

Clay mineral content and their impact on reservoir quality: Insight into the carbonate reservoirs oil fields, Central-Eastern Russia

Petroleum Research
Clay minerals are widespread in both sandstone and carbonate reservoirs. Previous studies have emphasized that clay minerals influence oil filtration in sandstones; however, very few studies to date have examined the influence of clay minerals in ...
