A large regional&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;gravity&lt;/span&gt;&lt;span&gt;&amp;nbsp;low over the Sierra Nevada can be explained by isostatic compensation of the range together with the effect of the relatively low-density rocks of the Sierra Nevada batholith. A broad&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;gravity&lt;/span&gt;&lt;span&gt;&amp;nbsp;ridge along the east side of the San Joaquin Valley shows excellent correlation with a similar magnetic ridge where the two sets of data are available, suggesting that both anomalies are caused by a dense, magnetic mass buried at an estimated depth of 5-10 miles. Seismic refraction measurements further indicate that the thickness of the earth's crust under the valley is less than 12 miles. Thus, the&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;anomalous&lt;/span&gt;&lt;span&gt;&amp;nbsp;mass is&amp;nbsp;&lt;/span&gt;&lt;span class="ScopusTermHighlight"&gt;in&lt;/span&gt;&lt;span&gt;&amp;nbsp;the lower part of the earth's crust and is conceivably related to the more mafic rocks of the earth's upper mantle.&amp;nbsp;&lt;/span&gt;&lt;/p&gt;</dc:description>
