One winonaite metal is similar in composition to low Au, low Ni IAB iron subgroup, indicating genetic relationship between them. Magnetic fractions of chondrule\u2010bearing acapulcoite and winonaite have intermediate chemical compositions of metals between H chondrites and EL chondrites. This fact indicates that the precursor materials of acapulcoite\u2013lodranites and winonaites were similar to H and\/or EL chondrites in chemical compositions. Magnetic fractions in acapulcoite\u2013lodranites have a large variety of chemical compositions. Most of them show enrichments of W, Re, Ir, Pt, Mo, and Rh, and one of them shows clear depletion in Re and Ir relative to those of chondrule\u2010bearing acapulcoite. Chemical compositional variations among acapulcoite\u2013lodranite metals cannot be explained by a single Fe\u2010Ni\u2010S partial melting event, but a two\u2010step partial melting model can explain it.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Yoshihiro Hidaka Naoki Shirai, Akira Yamaguchi, Mitsuru Ebihara Meteoritics &amp; Planetary Science First Published: 7 March 2019 LINK &#8220;We have studied magnetic fractions of five acapulcoites, three lodranites, and two winonaites to investigate chemical compositions&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[30,31,29,32],"tags":[2705,4212,4900,1820,1821],"_links":{"self":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/18127"}],"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=18127"}],"version-history":[{"count":1,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/18127\/revisions"}],"predecessor-version":[{"id":18128,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/18127\/revisions\/18128"}],"wp:attachment":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=18127"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=18127"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=18127"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
