  <dc:description>&lt;div id="aep-abstract-id4" class="abstract author"&gt;&lt;div id="aep-abstract-sec-id5"&gt;&lt;p&gt;UPb dating of single abraded zircon grains from a Pongola Supergroup rhyodacite sample collected in southern Swaziland yields a crystallization age of 2985±1 Ma. This date is significantly older than our previously reported UPb age determined on highly discordant and unabraded zircons from the same sample. The new zircon age indicates that the formation of the Pongola volcanics occurred not much later than the emplacement of the youngest granitoids thought to be broadly coeval with the Dominion Group (Robb&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;et al.&lt;/i&gt;, 1991), and before deposition of the Lower West Rand Group (Barton&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;et al.&lt;/i&gt;, 1989).&lt;/p&gt;&lt;/div&gt;&lt;/div&gt;</dc:description>
