In a deep magma ocean, iron would separate from silicate, sink, and eventually form a metallic core. In this stage, elemental partitioning between a metallic core and a magma ocean would have occurred and siderophile elements would be removed from the magma ocean. Such a chemically differentiated magma ocean formed the present-day Earth&#8217;s mantle. Previous studies have experimentally investigated carbon partitioning between iron liquid and silicate melt under high-pressure conditions and found that a terrestrial magma ocean should be more depleted in carbon than the present day. Thus, how and when the carbon abundance in the Earth&#8217;s mantle has been established is still poorly understood.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2019-09-carbon-earth.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">How and when was carbon distributed in the Earth?<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>It is generally accepted that planetary surfaces were covered with molten silicate, a &#8220;magma ocean,&#8221; during the formation of terrestrial planets.
