Highland materials cover most of the area, forming a group or rugged massifs close to the center of the map and more subdued terrain to the east. The highland units (&lt;/span&gt;&lt;span class="SpellingError SCXW123574835 BCX8"&gt;pItm&lt;/span&gt;&lt;span class="NormalTextRun SCXW123574835 BCX8"&gt;, &lt;/span&gt;&lt;span class="SpellingError SCXW123574835 BCX8"&gt;IpIh&lt;/span&gt;&lt;span class="NormalTextRun SCXW123574835 BCX8"&gt;) are probably mostly breccias formed by the Serenita&lt;/span&gt;&lt;span class="NormalTextRun SCXW123574835 BCX8"&gt;ti&lt;/span&gt;&lt;span class="NormalTextRun SCXW123574835 BCX8"&gt;s impact and pre-existing breccias excavated by this event.

To the west and southwest materials typical of lunar maria, almost certainly basalts, encroach upon and embay the highland terrain. Also in the west is a unit of special interest, a relatively young, usually &lt;/span&gt;&lt;span class="NormalTextRun SCXW123574835 BCX8"&gt;dark&lt;/span&gt;&lt;span class="NormalTextRun SCXW123574835 BCX8"&gt; material that mantles both terra and mare. It is draped over a wide variety of terrains in much of the western half of the map area and is interpreted as pyroclastic volcanics. The Apollo 17 site lies on this dark mantling material where it covers an embayment of mare materials between &lt;/span&gt;&lt;span class="NormalTextRun SCXW123574835 BCX8"&gt;upland massifs. At this locality, therefore, relatively young volcanic can be samples as well as the ancient deposits that form the highland massifs.&lt;/span&gt;&lt;/span&gt;&lt;span class="EOP SCXW123574835 BCX8" data-ccp-props="{&amp;quot;201341983&amp;quot;:0,&amp;quot;335559739&amp;quot;:160,&amp;quot;335559740&amp;quot;:259}"&gt;&amp;nbsp;&lt;/span&gt;&lt;/p&gt;</dc:description>
