  <dc:description>&lt;p&gt;&lt;span&gt;A contour map of the Precambrian surface for a part of&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;northeastern&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;New&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;Mexico&lt;/span&gt;&lt;span&gt;&amp;nbsp;has been prepared from&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;aeromagnetic&lt;/span&gt;&lt;span&gt;,&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;gravity&lt;/span&gt;&lt;span&gt;, and drill-hole data. The area extends approximately from the Colorado border south to latitude34° N., and from the foothills of the Sangre de Cristo Mountains east to longitude 104° W. Thirty-seven depths to Precambrian rocks were computed from&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;aeromagnetic&lt;/span&gt;&lt;span&gt;&amp;nbsp;anomalies. Regional gravityanomalies were generally not suitable for quantitative analysis, but the&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;gravity&lt;/span&gt;&lt;span&gt;&amp;nbsp;highs correlated with known areas ofbasement highs, providing a basis for contouring&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;in&lt;/span&gt;&lt;span&gt;&amp;nbsp;areas of meager depth control. Drill-hole data provided 61depths to basement&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;in&lt;/span&gt;&lt;span&gt;&amp;nbsp;and near the survey area. The contouring along the east edge of the Sangre de Cristo Mountainswas guided by exposures of Precambrian rocks. A principal feature of the contour map is the Sierre Grande Arch, a basement highland that trends southwestacross the area to the northwest part of Guadalupe County. Major depressions are outlined west of Vegas Junction, northeast of Santa Rosa, and north and northeast of Las Vegas. The largest of these, the Las Vegas basin, occupiesmore than 1,000 square miles and may be more than 10,000 ft deep Copyright.&amp;nbsp;&lt;/span&gt;&lt;/p&gt;</dc:description>
