  <dc:description>&lt;p&gt;Mixed-layer clays composed of randomly interstratified kerolite/stevensite occur as lake and/or spring deposits of probable Pliocene and Pleistocene age in the Amargosa Desert of southern Nevada, U.S.A. The percentage of expandable layers of these clays, determined from computer-simulated X-ray diffractograms, ranges from almost 0 to about 80%. This range in expandabilities most likely results from differences in solution chemistry and/or temperature at the time of formation. An average structural formula for the purest clay (sample P-7), a clay with about 70% expandable layers, is:&lt;/p&gt;&lt;p style="text-align: center;" data-mce-style="text-align: center;"&gt;[(Mg&lt;sub&gt;2.72&lt;/sub&gt;Al&lt;sub&gt;0.07&lt;/sub&gt;Fe&lt;sub&gt;0.03&lt;/sub&gt;Li&lt;sub&gt;0.09&lt;/sub&gt;)(Si&lt;sub&gt;3.96&lt;/sub&gt;Al&lt;sub&gt;0.04&lt;/sub&gt;)O&lt;sub&gt;10&lt;/sub&gt;(OH)&lt;sub&gt;0.2&lt;/sub&gt;]&lt;sup&gt;-0.21&lt;/sup&gt;[X&lt;sup&gt;+&lt;/sup&gt;&lt;sub&gt;0.21&lt;/sub&gt;]&lt;sup&gt;+0.21&lt;/sup&gt;&lt;/p&gt;&lt;p&gt;The data suggest that talc, kerolite, and stevensite form a continuous structural series based on layer charge.&lt;/p&gt;</dc:description>
