Important gold and silver deposits of Colorado. <br />The figure highlights the location of the La Plata mining district at the extreme southwestern end <br />of the Colorado Mineral Belt (from Colorado Geological Survey) <br />Later scientists have come to understand that this northeasterly- trending zone <br />reflects a deep zone of fracturing and igneous intrusion that formed during the <br />Laramide Orogeny between 75 and 40 million years ago. These intrusions and <br />fractures are thought to have followed a much older Precambrian -age zone of <br />crustal weakness and shearing. <br />January 2007 <br />May Day- Idaho Mine Colorado <br />
