Etude par diffraction des rayons-X de la composition minéralogique des fractions silteuse et argileuse du site 645B, au large de la marge orientale de l'île de Baffin. Comparaison avec les sédiments de la plate-forme et des fjords adjacents
Grain-size analysis by laser diffractometry : comparison with the sieve-pipette method
Clay mineral ; Grain size distribution ; Methodology ; Soil ; Soil properties ; Soil science ; X-raydiffractionanalysis
Results of a traditional sedimentation technique for grain-size analysis (the sieve-pipette method) were compared with those of a laser diffraction grain-size analyser, the Coulter LS-100. Milled quartz samples and silty soil samples were used

A new method for the analysis of aggregate disintegration in water was tested using aeolian sediment samples. Repeated laser diffractionanalysis of a single sample circulating in deionized water provides a detailed view of the changes in particle
analysis and X-raydiffraction and the results analyzed by principal component analysis (PCA) and cluster analysis. The investigation clearly showed that the Frederiksgave pots were not locally produced but came from other production sites indicating
cement. Chemical analysis, X-raydiffraction data and field observations suggest that salt weathering is the most important cause of disintegration, but dissolution of calcite cement also occurs in calcareous sandstones. Cavernous weathering at Capitol
oxide coatings have been investigated by a range of analytical techniques, including X-raydiffraction (XRD), infrared-spectral (IR), differential thermal analysis–thermal gravimetric (DTA–TG), scanning electron microscopy and energy-dispersive X-ray
X-ray fluorescence analysis as a rapid method of identifying tephras discovered in archaeological sites in Tephra studies.

Volcanic ash layers from three major Holocene eruptions are found throughout southern British Columbia and are useful stratigraphic markers. Here the AA. show that energy dispersive X-ray fluorescence analysis and alpha counting are useful
using the ion adsorption method, a micro-electrophoresis method and the X-raydiffractionanalysis. Results indicated that all these soil samples, 4 ultisols collected respectively from Liuzhou, Guangxi, Changsha and Hunan Province, contained kaolinite
This study revises the pedological record of the Rocourt-paleosol complex, an important pedo-stratigraphic marker for the Eemian and Early Weichselian. Soil morphological features and depth functions of X-raydiffraction, grain-size distribution
, CEC, base saturation, total Fe, Al, K, Na and Ca content, pH and electrical conductivity were established to reconstruct deposition dynamics, weathering and carbonate content of the parent material. Texture analysis confirms the petrostratigraphic
in this region. The X-raydiffraction and scanning electron microscope analysis results indicate that the contents, particle sizes, shapes and structures of secondary minerals, such as iron and clay minerals, are distinctly different in ferruginous nodular
of laboratory and wildfire ash from the Northern Rocky Mountain region of the United States. A variety of techniques were used including scanning electron microscope, X-raydiffraction, thermogravimetric analysis, and conventional soil science techniques
of the soil clay fraction with time were investigated using ion adsorption, micro-electrophoresis, and X-raydiffractionanalysis. It is highlighted that the content of kaolinite and gibbsite increased with increasing basalt age and degree of soil development
