  <dc:description>&lt;p&gt;&lt;span&gt;Part I, T. S. Lovering. Preliminary work&amp;nbsp;&lt;/span&gt;in&lt;span&gt;&amp;nbsp;the&amp;nbsp;&lt;/span&gt;Tintic&lt;span&gt;&amp;nbsp;&lt;/span&gt;district&lt;span&gt;,&amp;nbsp;&lt;/span&gt;Utah&lt;span&gt;, determined the relative distance of migration of&amp;nbsp;&lt;/span&gt;ore&lt;span&gt;&amp;nbsp;&lt;/span&gt;metals&lt;span&gt;&amp;nbsp;&lt;/span&gt;in&lt;span&gt;&amp;nbsp;moist carbonate and silicic&amp;nbsp;&lt;/span&gt;wall&lt;span&gt;&amp;nbsp;&lt;/span&gt;rocks&lt;span&gt;&amp;nbsp;&lt;/span&gt;near&lt;span&gt;&amp;nbsp;&lt;/span&gt;ore&lt;span&gt;, and&amp;nbsp;&lt;/span&gt;in&lt;span&gt;&amp;nbsp;ground water having a very sluggish circulation through mineralized ground. The analyses of efflorescences&amp;nbsp;&lt;/span&gt;in&lt;span&gt;&amp;nbsp;the&amp;nbsp;&lt;/span&gt;Tintic&lt;span&gt;&amp;nbsp;Standard mine openings at suitable localities indicated that under the conditions existing during the past 25 years lead has not moved perceptibly; gold has migrated only a few inches; copper has moved a few score feet at most and only&amp;nbsp;&lt;/span&gt;in&lt;span&gt;&amp;nbsp;acid solutions; and zinc has traveled hundreds of feet, but not as far as some silver. Silver may travel far&amp;nbsp;&lt;/span&gt;in&lt;span&gt;&amp;nbsp;the oxidized zone, but if it comes&amp;nbsp;&lt;/span&gt;in&lt;span&gt;&amp;nbsp;contact with sulfides its migration is quickly halted. The chief chemical factors that influence the migration of&amp;nbsp;&lt;/span&gt;metals&lt;span&gt;&amp;nbsp;&lt;/span&gt;in&lt;span&gt;&amp;nbsp;&lt;/span&gt;supergene&lt;span&gt;&amp;nbsp;solutions are the hydrogen ion concentration (pH) of hydrolysis of the&amp;nbsp;&lt;/span&gt;metal&lt;span&gt;&amp;nbsp;ion, the solubility of sulfates of the&amp;nbsp;&lt;/span&gt;metals&lt;span&gt;, and the position of the&amp;nbsp;&lt;/span&gt;metals&lt;span&gt;&amp;nbsp;&lt;/span&gt;in&lt;span&gt;&amp;nbsp;Schuermann's series if the solutions are&amp;nbsp;&lt;/span&gt;in&lt;span&gt;&amp;nbsp;contact with sulfides for a considerable time.&amp;nbsp;&lt;/span&gt;&lt;/p&gt;</dc:description>
