☮ ♥ ♬ 🧑💻<p>“we report two newly recognized episodes of basaltic volcanism with Pb-Pb dating for basalt fragments returned by the <a href="https://ioc.exchange/tags/Change6" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Change6</span></a> mission. One high-Al basalt fragment dated at 4,203 ± 4 million years ago (Ma) has a source 238U/204Pb ratio (µ value) of ~1,620, implying a KREEP-rich (K, rare earth elements, and P) source for this oldest-known occurrence of <a href="https://ioc.exchange/tags/basaltic" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>basaltic</span></a> <a href="https://ioc.exchange/tags/volcanism" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>volcanism</span></a> among returned samples”</p><p>🌘🌋</p><p><a href="https://ioc.exchange/tags/lunar" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>lunar</span></a> / <a href="https://ioc.exchange/tags/moon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>moon</span></a> / <a href="https://ioc.exchange/tags/volcano" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>volcano</span></a> <<a href="https://www.nature.com/articles/s41586-024-08382-0" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">nature.com/articles/s41586-024</span><span class="invisible">-08382-0</span></a>></p>
