The CLR is asymmetrical with a steeper eastern slope and has an average depth of less than 1,000 m (3,300 ft). It formed south of or near the Equator together with the remaining western continental margin of India, when India separated first from Madagascar in the Mid-Cretaceous and then from the <a href="/wiki/Seychelles" title="Seychelles">Seychelles Islands</a> in the Late Cretaceous.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Extent">Extent</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Chagos%E2%80%93Laccadive_Ridge&action=edit&section=1" title="Edit section: Extent"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The CLR extends northward for <abbr title="circa">c.</abbr> 2,550 km (1,580 mi) from 10°S at the southern end of the Chagos Archipelago to 14°N around the <a href="/wiki/Adas_Bank" title="Adas Bank">Adas Bank</a>.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> The second element of the name is for the <a href="/wiki/Lakshadweep_Islands" class="mw-redirect" title="Lakshadweep Islands">Lakshadweep Islands</a>, among the islands of <a href="/wiki/Lakshadweep" title="Lakshadweep">Lakshadweep</a>.
