Comparative study of illite clay and illite-based geopolymer products

IOP Conference Series: Materials Science and Engineering, 2011
Quaternary (Q-clay) clayey deposits are one of the dominating parts of mineral raw materials of the sedimentary cover at present area of Latvia. These clays can be characterised by illite content up to 75-80 %. Two ways for use of illite clays were studied: conventional and geopolymers method.

Selected Physical and Geotechnical Properties of Loess in Wairarapa Valley, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.
Loess up to 10 m thick covers marine terraces, old river aggradation terraces, and gentle hill country slopes in Wairarapa, New Zealand. In the drier eastern and southern parts of Wairarapa, the loess is subject to dry summer and autumn and wet winter and spring in most years.

GIS–TOPSIS assessment of soil and water constraints on sunflower in arid Algeria

Agronomy Journal, Volume 118, Issue 6, November/December 2026.
Abstract Identifying land capable of sustaining oilseed crops under increasing aridity is central to strengthening agricultural resilience in North African drylands. We developed a statistically validated, spatially explicit land‑suitability framework that integrates geographic information systems (GIS) with the technique for order preference by ...

Adsorption of strontium and caesium onto an Na-illite and Na-illite/Na-smectite mixtures: Implementation and application of a multi-site ion-exchange model

, 2018
International audienceThe application of a multi-site ion-exchange (MSIE) model to the prediction of contaminant behaviour onto soils or sediments requires a coherent adsorption database. Following the same approach exposed in preceding works on smectite

Disentangling the depositional, tectonic and diagenetic history of a unique case of rhombic calcite in marine carbonate scree‐like deposits in the Cretaceous Cauvery Basin

The Depositional Record, Volume 12, Issue 5, November 2026.
A succession of marine deposited scree deposits got exposed to meteoric fluids due to sea level drop or tectonic uplift. This potentially caused a unique form of diagenetic transformation in scree deposits, that is the formation of micro rhombic calcite.

Hydrothermal synthesis of ammonium illite

, 1998
Synthetic gel and glass of illitic composition, natural kaolinite, and mixed-layer illite-smectite were used as starting materials for hydrothermal synthesis of ammonium illite. Ammonium illite was prepared from synthetic gel by hydrothermal treatment at

Application of faujasite synthesized from illite to the removal of Cr3+ and Ni2+ from electroplating wastewater

Revista Ion, 2013
The synthesis of faujasite type zeolite from an illite-rich raw material by an alkaline fusion step prior to hydrothermal treatment was investigated. The synthesis products were characterized by X-ray fluorescence, X-ray diffraction, scanning electron ...

Permian sedimentary sequence containing analcimolite and authigenic aegirine from the Boskovice Basin (Bohemian Massif, Czechia)

The Depositional Record, Volume 12, Issue 5, November 2026.
The Permian freshwater lacustrine sedimentary sequence rich in analcime, with unusual authigenic aegirine and NaFe3+ clinopyroxene. Product of ashfall directly linked with fossil accumulation (Konzentrat‐Lagerstätte). Abstract The Early Permian freshwater lacustrine sedimentary sequence in the vicinity of Bačov (Czechia) is world‐famous for its rich ...

Performance Evaluation of Low-Grade Clay Minerals in LC³-Based Cementitious Composites

Solids
The cements industry is increasingly under pressure to reduce carbon emissions while maintaining performance standards. Limestone calcined clay cement (LC3) presents a promising low-carbon alternative; however, its performance depends significantly on ...
