説明
<jats:title>So Different and So Similar</jats:title> <jats:p> Most known meteorites from Mars fit into one class. <jats:bold> Agee <jats:italic>et al.</jats:italic> </jats:bold> (p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6121" page="780" related-article-type="in-this-issue" vol="339" xlink:href="10.1126/science.1228858">780</jats:related-article> , published online 3 January; see the Perspective by <jats:bold> <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6121" page="771" related-article-type="in-this-issue" vol="339" xlink:href="10.1126/science.1232490">Humayun</jats:related-article> </jats:bold> ) describe a meteorite, NWA 7034, which shares some characteristics with other martian meteorites but does not fit within the usual classification. NWA 7034 matches the composition of Mars' surface but is also richer in water than other martian meteorites, and has different oxygen isotope composition, which suggests the existence of multiple oxygen isotopic reservoirs within Mars. Its radiometric age of 2.1 billion years makes it a unique sample of the Amazonian period on Mars. </jats:p>
