However, this differentiation remains enigmatic: their small size precludes gravity-driven permeable flow, and enstatite exhibits a high melting temperature. Here, we report high-pressure melting experiments on EH3 chondrite, coupled with three-dimensional X-ray computed tomography, showing that more than 20% of silicate partial melting can enable efficient metal segregation. Thermodynamic simulations of EH chondrite-like embryos thermal evolution further demonstrate that heat from radioactive decay allows core formation only if embryos accreted within 1.4\u2009Myr post-CAIs. In contrast, EH chondrite parent bodies formed later (1.92\u20132.0\u2009Myr post-CAIs) with radii of 110\u2013190\u2009km. Our findings suggest two distinct evolutionary trajectories of EH chondrite-like embryos, providing constraints on core formation in small planetary embryos and fundamental references for the formation of planets in the early solar system.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Qiong Li, Wei Du, Jing Yang, Chuan Zhang, Di Yao, Keqing Zong, Feiyang Chen, Yonggang Wang &amp; Yun Liu Communications Earth &amp; Environment, Published: 25 July 2026 LINK (OPEN ACCESS)PDF (OPEN ACCESS) &#8220;Enstatite chondrites-like impactors&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[112,25,17,73],"tags":[1817,1021,1813,2660,2343,1169,3219,1627],"_links":{"self":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/42496"}],"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=42496"}],"version-history":[{"count":1,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/42496\/revisions"}],"predecessor-version":[{"id":42497,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/42496\/revisions\/42497"}],"wp:attachment":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=42496"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=42496"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=42496"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
