Overconsolidation of Alluvial Clays

On Clays

Base-exchange determinations were made on selected clays of the montmorill0niteillite group to test this method as an analytical tool for the analysis of mixed-layer aggregates. The relatively rapid manganese method developed by Bower and Truog was used and its precision determined oll monodisperse, monomineralic fractions and monodisperse fractions of prepared mixtures of illite and montmorill...

ESR of clays

Electron spin resonance (ESR) spectroscopy has contributed significantly to the identification and characterization pf paramagnetic impurities associated with clays, Following a brief discussion of the general principles of the technique, a review is given of the application of ESR to the study of those paramagnetic species (chiefly iron and radiation-induced lattice defects) located either wit...

Ion Exchange Reactions of Clays

I t has been recognized for many ypars that many aspects of clay technolofcy including soil treatment and drilling nnul treatment must remain in an essentially empirical state until a basis for the understanding of ion exchange reactions is established. Much of the work on ion exchange reactions of clays in the i)ast has been directed toward establishing total exchange capacities or determining...

Chemical Characterization of Tablets, Sealing Clays, and Source Clays from Tell Leilan, Syria

When attempting to deal with questions involving the emergence and evolution of ancient complex societies, one of the major problems faced by researchers is how to monitor abstract processes from the material remains recovered in excavation. Clay sealings and tablets, which provide multiple independent lines of information: iconographic and/or epigraphic; functional (type of sealing i.e. door l...
