Wayne Mountjoy Harry C. Starkey 1973 <p>Chemical analyses, X-ray diffraction data, and cation&nbsp;exchange determinations are given for a lithium-bearing smectite. The&nbsp;X-ray data and Greene-Kelly's lithium test indicate the presence of both&nbsp;dioctahedral and trioctahedral phases. The exchange determinations&nbsp;indicate that the lithium is in the structure of the clay, and the&nbsp;chemical data are intermediate between those for hectorite and&nbsp;montmorillonite. All data indicate that the clay is a mixture of&nbsp;hectorite and montmorillonite.</p> application/pdf en U.S. Geological Survey Identification of a lithium-bearing smectite from Spor Mountain, Utah article
