Abstract: Area-weighted thickness distributions of fundamental illite particles for samples of illite and illite-smectite from seven locations (including bentonites and hydrothermally altered pyroclas...
Abstract: The rheological behavior of concentrated lateritic suspensions from Cuba is affected by mineral composition and particle size. Electrophoretic mobility and yield stress were considered. The ...

Various size fractions of several samples of glauconitic clay and illite were heated stepwise under vacuum for extended periods to: 1) evaluate radiogenic-argon (Ar) yields in relation to composition ...
Infrared spectra of two minerals; Urkut quartz (Hungary) and a Swedish feldspar, of different origin with different physical characteristics and crystallinity were studied. Samples were taken after ap...
Effects of particle size, crystallinity and the amount of the structural water in kaolinites on their infrared spectra, were studied. The samples were ground in a vibrating ball-mill, and infrared and...
Previous work has shown that some clay particles orient at both low and high voltages due to a permanent dipole and an induced dipole, respectively, whereas other clays under similar short-duration pu...
A vermiculite (Libby, Montana) sample obtained from the Zonolite company contained mostly coarse-grained separates with only 8? per cent clay. The 2?0 祄 fraction was used for particle-size reduction s...
Crude sedimentary kaolin clay from central Georgia, U.S.A., which had a wide distribution of particle size, was divided into several size fractions by repeated sedimentation in water. The resulting fr...
Sorption of K from mixed KCl and CaCl2 solutions by K-depleted, Ca-saturated phlogopite was studied to determine the effect of particle size. The experiments were done at room temperature with 25 mg o...
Abstract: Completeness of exchange of K from muscovite by Ba2+ ions decreased with particle size below 20 ? Accompanying K exchange at 120癈, using a repeated batch technique, was a marked loss of Si a...
Hydroxy-Al and -Fe interlayers were prepared in 乬mono-mineralic乭 fine and coarse clay montmorillonite and coarse clay and silt vermiculite at 3亱C and 21亱C. The formation of hydroxy interlayers was eva...
A vermiculite regolith sample from Llano, County, Texas, was divided into 16?2, 8?6, 4?, 2?, 1?, 綎1, 紪? 1 10 柤, and 5 100 ?1 10 micron equivalent spherical diameter size-classes. A well-crystallized v...
