In this study, meteorite Ribbeck (2024 BX1, SAR 2736) from the recently fallen asteroid (21.01.2024), collected right after the fall, was investigated. This meteorite is classified as a coarse-grained brecciated aubrite. The main mineral phases are enstatite, albite, and forsterite. X-ray structural analysis and Raman Spectroscopy indicate its complex metamorphic history, starting with magmatic crystallization and following metamorphic evolution (e.g., impacting). Energy-dispersive. X-ray spectroscopy (EDS) confirms the presence of unusual minerals such as oldhamite, brezinanite (daubr\u00e9elite, zolenskyite), wassonite\/heideite, and alabandite, that formed under highly reductive conditions, with oxygen fugacity \u0394IW (logfO2) in a range of -5 to -7. Similar conditions can be found on the Mercury or the Asteroid 3103 Eger. Magnetic measurements confirm that the primary magnetic components in the meteorite are accessory minerals &#8211; sulphides and metallic nodules.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Mieszko Ko\u0142odziej, Danuta Michalska, Karol Za\u0142\u0119ski, Igor Iatsunskyi, Andrzej Muszy\u0144ski &amp; Emerson Coy Scientific Reports, Volume 15, article number 6866, Published: 26 February 2025 LINK (OPEN ACCESS)PDF (OPEN ACCESS) &#8220;Meteorites are a unique source of&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[38,6616,47],"tags":[1826,3820,6615,1832],"_links":{"self":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/37563"}],"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=37563"}],"version-history":[{"count":1,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/37563\/revisions"}],"predecessor-version":[{"id":37564,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/37563\/revisions\/37564"}],"wp:attachment":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=37563"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=37563"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=37563"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
