Chris Rowan<p>This is a nice write-up of how plate tectonics may have got going on Earth: a progressive development over a couple of billion years, from no plate boundaries, to localised and intermittent ones, to a full planetary system, makes a lot of sense. It would also explain why different lines of evidence produce such different start dates: it's a convolution of a fragmentary and intermittent process and a fragmentary and intermittent geological record.<br><a href="https://scicomm.xyz/tags/geology" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>geology</span></a> <a href="https://scicomm.xyz/tags/PlateTectonics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>PlateTectonics</span></a></p><p><a href="https://www.nature.com/articles/d41586-024-02602-3" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">nature.com/articles/d41586-024</span><span class="invisible">-02602-3</span></a></p>
