The possibility exists that some late projectiles were differentiated and left an incomplete HSE record in Earth\u2019s mantle. Even in this case, various isotopic constraints strongly suggest that the late-accreted mass did not exceed 1 per cent of Earth\u2019s mass, and so the HSE clock still robustly limits the timing of the Moon-forming event to significantly later than 40\u2009Myr after condensation.<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>Jacobson SA, Morbidelli A, Raymond SN, O\u2019Brien DP, Walsh KJ and Rubie DC (2014) Nature 508, 84\u201387 (03 April 2014) doi:10.1038\/nature13172 LINK Using HSE abundance measurements13, 14, we determine a Moon-formation age of 95\u2009\u00b1\u200932\u2009Myr after&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[72,112,115,71],"tags":[80,1857,114],"_links":{"self":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/1841"}],"collection":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=1841"}],"version-history":[{"count":1,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/1841\/revisions"}],"predecessor-version":[{"id":1842,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/1841\/revisions\/1842"}],"wp:attachment":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=1841"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=1841"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=1841"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
