  <dc:description>&lt;p&gt;&lt;span&gt;Water saturated with CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;at about 25°C was percolated through mixed beds of limestone or marble fragments and montmorillonite, “illite” and kaolinite in polyethylene tubes for six and fortyfive complete runs. The leachates were analysed for SiO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;, A1&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;O&lt;/span&gt;&lt;sub&gt;3&lt;/sub&gt;&lt;span&gt;&amp;nbsp;and Fe&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;O&lt;/span&gt;&lt;sub&gt;3&lt;/sub&gt;&lt;span&gt;, but only SiO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;was found. The minerals lost SiO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;in this order: montmorillonite &amp;gt; kaolinite &amp;gt; “illite”. The differential removal of SiO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;during the short period of these experiments suggests a mechanism for the accumulation of bauxite deposits associated with limestones.&lt;/span&gt;&lt;/p&gt;</dc:description>
