  <dc:description>&lt;p&gt;&lt;span&gt;The Crandon massive sulfide deposit is covered by as much as 65 m of glacial drift. Soil gas was sampled at a depth of 0.5 m along several traverses over the deposit. Gases showing anomalies that correlate with the underlying deposit include CO&amp;nbsp;&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;, CH&amp;nbsp;&lt;/span&gt;&lt;sub&gt;4&lt;/sub&gt;&lt;span&gt;&amp;nbsp;, and O&amp;nbsp;&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;. CO&amp;nbsp;&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;and CH&amp;nbsp;&lt;/span&gt;&lt;sub&gt;4&lt;/sub&gt;&lt;span&gt;&amp;nbsp;show positive anomalies with a background/anomaly ratio as high as 1 to 25, whereas O&amp;nbsp;&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;shows negative anomalies. Oxidation of the sulfides with the production of sulfate is the probable chemical reaction producing some of the gas anomalies. The CH&amp;nbsp;&lt;/span&gt;&lt;sub&gt;4&lt;/sub&gt;&lt;span&gt;&amp;nbsp;anomalies may result from thermal cracking of hydrocarbon precursors. These results indicate that measurement of soil gases should provide a useful exploration tool in glacial terrain.&lt;/span&gt;&lt;/p&gt;</dc:description>
