Journal Article
Origin of dunites and of olivine-rich inclusions in basaltic rocks
Journal ArticleDOI
The origin of high sodium bicarbonate waters in the Atlantic and Gulf Coastal Plains
TL;DR: In this article it was shown that carbonaceous material can act as a source of carbon dioxide, which, when dissolved in water, enables it to take into solution more calcium carbonate, and if base exchange materials are also present to replace calcium with sodium, a still greater amount of bicarbonate can be held in solution.
Journal Article
Geochemical studies of clay minerals: II—relation between ionic substitution and swelling in montmorillonites
Journal ArticleDOI
Geochemical studies of clay minerals III. The determination of free silica and free alumina in montmorillonites
TL;DR: In this article, a method for determination of free silica by the method proposed made possible the derivation of logical formulas for several specimens of montmorillonites for which the formulas could not be derived from the analyses alone.
Journal ArticleDOI
The Relation Between Composition and Swelling in Clays
TL;DR: In this paper, the authors reviewed the mechanism of hydration and swelling of different types of clays and some theories proposed as to the cause of the clays' hydration, including broken bonds on the edges of the sheets.
