Crustal material in this area of large basins and craters has been redistributed repeatedly by giant impacts. The early historical record of these events is apparently preserved in a complex of interlayered breccias, which may be partly exposed in the walls of the larger craters. Orientale, the last &lt;/span&gt;&lt;span class="SpellingError SCXW152142341 BCX8"&gt;multiringed&lt;/span&gt;&lt;span class="NormalTextRun SCXW152142341 BCX8"&gt; basin, was formed early in lunar history during the wanning stages of high impact flux by a large body probably impacting the surface obliquely from the northeast. Ejecta from this impact was widely scattered by over the Moon and appears to form some of the &lt;/span&gt;&lt;span class="ContextualSpellingAndGrammarError SCXW152142341 BCX8"&gt;plains&lt;/span&gt;&lt;span class="NormalTextRun SCXW152142341 BCX8"&gt; materials. Although the major landforms of the Oriental basin were developed instantaneously in geologic terms, isostatic adjustments were more protracted; the accompanying structural dislocations including concentric and radial faults in the floor material may have continued &lt;/span&gt;&lt;span class="NormalTextRun SCXW152142341 BCX8"&gt;u&lt;/span&gt;&lt;span class="NormalTextRun SCXW152142341 BCX8"&gt;p to the time of mare basalt flooding after basin formation. Subsequent impacts have produced craters generally less than 60 km diameter.&lt;/span&gt;&lt;/span&gt;&lt;span class="EOP SCXW152142341 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>
