The samples were subjected to different heating temperatures and room temperature M\u00f6ssbauer spectra were collected after cooling down these samples. The untreated meteorite samples showed the presence of olivine, pyroxene, troilite, and Fe\u2013Ni alloy (kamacite\/taenite) minerals. The decomposition of such iron based minerals started at or above 600\u00b0C towards hematite iron phase for all these meteorites. More interestingly, at about 1000\u00b0C or above, all initial mineral phases got converted into either hematite and\/or magnetite. The present study provides a clue to understand the mechanism of conversion of minerals in ordinary chondrites.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ambesh Dixit, Beena Bhatia &amp; R P Tripathi Journal of Earth System Science, Volume 130, Article number: 191 (2021) LINK &#8220;We used 57Fe M\u00f6ssbauer spectroscopic measurements on untreated and controlled thermally treated Ararki, Didwana, and&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6,23,24,7],"tags":[3073,6106,6108,6107,595,1807],"_links":{"self":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/28821"}],"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=28821"}],"version-history":[{"count":1,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/28821\/revisions"}],"predecessor-version":[{"id":28822,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/28821\/revisions\/28822"}],"wp:attachment":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=28821"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=28821"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=28821"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
