Abstract This study focuses on the mineralogical and geotechnical characterization of northern Moroccan clays from Tangier Tetouan areas compares them with main clay deposits used in ceramic industry (from Meknes, Fes, Salé Safi regions). Sampled were analysed by X-ray diffraction bulk (<2 μm) fractions to identify assemblages outcrops. Further analyses conducted determine particle size distribution (laser analyser), total organic matter content (Loss- On-Ignition measurements) Atterberg...
This paper aims to study the provenance of archaeological Saadien ceramics (16th century, Marrakech) based on chemical, mineralogical and lead isotope composition clays used as raw materials in manufacture Morocco collected six major potter sites Marrakech (Ourika I II, Saada II Mzouda) Fez (Benjlikh). The clay isotopic signatures these are compared compositions decorated from El Badi Palace Tombs, most visited Marrakech, described World Heritage by UNESCO. chemical was determined using...
Abstract The composition of Rhassoul clay is controversial regarding the nature pure-mineral fraction which claimed to be stevensite rather than saponite. In this study, raw and mineral fractions were characterized using various techniques including Fourier transform infrared spectroscopy magic angle spinning nuclear magnetic resonance (MAS NMR). isolated fine contained a larger amount Al (>1 wt.%) that reported for other occurrences. 27 MAS NMR technique confirmed in equally split...
This study aims at evaluating the potential suitability of Tetouan and Meknes (central Morocco) clay material as raw materials in various ceramic applications by investigating their textural, chemical, thermal firing characteristics. Textural properties were identified specific surface area, cation exchange capacity (CEC) bulk density (ρs). Chemical assessed using XRF TG/DTA techniques, respectively. Firing characteristics temperatures from 800℃ to 1100℃ determined linear shrinkage, loss on...
Abstract Palygorskite has been identified as a major constituent of the clay fraction in mid-Cretaceous deposits Meseta, Middle Atlas, and Rif central northern Morocco. Two types palygorskite are differentiated, based on morphology crystallites, bio- lithofacies associations containing sediments. Type 1 occurs sections Meseta where mineral displays bundles long fibres under electron microscope is associated with shallow marine carbonate evaporite facies. 2 was found Rif, mostly shorter...
The effects of high-pressure treatment on the colour (objective measurement) and sensory characteristics white grape juice were studied during storage at 4 °C for 60 days. Grape was subjected to three different treatments: 400 or 500 MPa 2 u °C, 40 10 min. Untreated used as control. Colour parameters (CIE L * a b *), hue angle (tan m 1 */ chroma {( + ) 1/2 }, luminosity Q *{(10 log( *) 100} saturation S *( C measured. Juices evaluated sweetness, acidity, off-flavour aroma. High-pressure...
Abstract Clays from the Saïss basin (northern Morocco) used traditionally in ceramic industry Fez area were studied using mineralogical and physicochemical techniques to evaluate their potential suitability as raw materials for ceramics manufacture. X-ray diffraction was determine composition. The physical properties determined particle-size distribution consistency limits. chemical composition fluorescence analysis Fourier-transform infrared spectrometry. structural changes of mineral...
