  <dc:description>&lt;p&gt;&lt;span id="_mce_caret" data-mce-bogus="1" data-mce-type="format-caret"&gt;&lt;span&gt;Major and selected minor elements were determined in seven whole rock fragments, five portions of pulverized lunar rock, and the lunar soil. Three different rock types were represented: vesicular, fine-grained basaltic rocks; medium- to coarse-grained, vuggy gabbroic rocks; and breccia. The ranges (in percent) for the major constituents of the lunar samples are: SiO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;, 38 to 42; Al&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;O&lt;/span&gt;&lt;sub&gt;3&lt;/sub&gt;&lt;span&gt;, 8 to 14; total iron as FeO, 15 to 20; MgO, 6 to 8; CaO, 10 to 12; Na&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;O, 0.5 to 1; K&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;O, 0.05 to 0.4; TiO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;, 8 to 13; MnO, 0.2 to 0.3; and Cr&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;O&lt;/span&gt;&lt;sub&gt;3&lt;/sub&gt;&lt;span&gt;, 0.2 to 0.4. The high reducing capacity of the samples strongly suggests the presence of Ti(III).&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;</dc:description>
