  <dc:description>&lt;p&gt;&lt;span&gt;The Lamprecht and Felder deposits are roll-type deposits hosted by the Miocene Oakville Sandstone. Four distinct stages of FeS&amp;nbsp;&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;mineral formation are recognized: (1) a generation of isotopically light (delta&amp;nbsp;&lt;/span&gt;&lt;sup&gt;34&lt;/sup&gt;&lt;span&gt;&amp;nbsp;S &amp;lt; -20 per mil) preore pyrite, (2) a generation of isotopically light (delta&amp;nbsp;&lt;/span&gt;&lt;sup&gt;34&lt;/sup&gt;&lt;span&gt;&amp;nbsp;S &amp;lt; -20 per mil) marcasite that formed mostly before, but also during ore deposition, (3) a postore generation of isotopically heavy pyrite (delta&amp;nbsp;&lt;/span&gt;&lt;sup&gt;34&lt;/sup&gt;&lt;span&gt;&amp;nbsp;S &amp;gt; 0 per mil), and (4) a yet later generation of marcasite with isotopically light sulfur close to the values of stages 1 and 2. Complex zone of mixing between saline brines migrating up the fault from depth and oxygenated meteoric water recharging at the outcrop. Bacterial activity.&lt;/span&gt;&lt;/p&gt;</dc:description>
