  <dc:description>&lt;p&gt;&lt;span&gt;In a study of the relationship of&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;magnetic&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;anomalies&lt;/span&gt;&lt;span&gt;&amp;nbsp;to the magnetite content and structure of layered Precambrian iron-formations, the effective induced and remanent&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;magnetizations&lt;/span&gt;&lt;span&gt;&amp;nbsp;of the&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;Biwabik&lt;/span&gt;&lt;span&gt;&amp;nbsp;iron-formation were determined by analyses of aeromagnetic&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;anomalies&lt;/span&gt;&lt;span&gt;&amp;nbsp;recorded 1,000 ft above the&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;Biwabik&lt;/span&gt;&lt;span&gt;&amp;nbsp;in areas of known geology. The induced&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;magnetization&lt;/span&gt;&lt;span&gt;&amp;nbsp;along the layers is relatively insignificant because the formation is almost perpendicular to the earth's&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;magnetic&lt;/span&gt;&lt;span&gt;&amp;nbsp;field. For the relatively unmetamorphosed iron-formation of the Main&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;Mesabi&lt;/span&gt;&lt;span&gt;&amp;nbsp;district, the dominant&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;magnetization&lt;/span&gt;&lt;span&gt;&amp;nbsp;was found to be across the layers, about 0.012 gauss, and most likely induced. For the strongly metamorphosed iron-formation of the East&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;Mesabi&lt;/span&gt;&lt;span&gt;&amp;nbsp;district, the dominant&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;magnetization&lt;/span&gt;&lt;span&gt;&amp;nbsp;was found to be along the layers, about 0.100 gauss, and remanent. These values are used as bases for explaining aeromagnetic&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;anomalies&lt;/span&gt;&lt;span&gt;&amp;nbsp;from correlatives of the&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;Biwabik&lt;/span&gt;&lt;span&gt;&amp;nbsp;iron-formation in the Gunflint, Cuyuna, and Gogebic districts.&lt;/span&gt;&lt;/p&gt;</dc:description>
