Diagenesis of organic matter and fine clay minerals: a comparative study
TL;DR: In this paper, a geochemical study of fine clay minerals and organic matter in subsurface shale samples from the Canadian Northwest Territories has been made, where the mixed layer clays are transformed during thermal diagenesis to a pseudo-quaternary system (smectitevermiculite-illite-chlorite) by incorporation of amorphous inorganic material, and the first clay dehydration occurs prior to hydrocarbon generation and is accompanied by adsorption of K + and substitution of Al 3+ for Si 4+ in the clay lattice.
BookDOI
The Science of Clays
TL;DR: Greenfield, Amy Butler, and Pastoureau as discussed by the authors described the history of the color of red as "the quest for the colour of desire" and used it in their book A Perfect Red: Empire, Espionage, and the Quest for the Color of Desire.
Journal ArticleDOI
Dehydration and rehydration of saponite and vermiculite
TL;DR: In this paper, the rehydration properties and behavior of interlayer cations of Ca-, Mg-, Na-, and K-saturated homoionic saponite and vermiculite heated at various temperatures were examined.

Experimental conversion of biotite to hydrobiotite.
V. C. Farmer,Michael T. Wilson +1 more
TL;DR: The transformation of biotite to hydrobiotite is accomplished in conditions which throw some light on the mechanism involved, and complete regular interstratification has only been achieved by reversing the reaction so that vermiculite is converted to a mica-like phase by controlled sorption of K+ and other ions.

Pedogenic weathering of tonalite in southern California
TL;DR: In this paper, the authors studied the weathering of a fragment of tonalite (quartz diorite) in southern California to depths of more than 30 m. The particle density of the resulting fragments is the same as that of the rock (2.75 g/cm 3 ).
