The abundances of the<jats:styled-content style=\"fixed-case\">HSE<\/jats:styled-content>were therefore largely unaffected by late\u2010stage secondary processes such as shock or terrestrial weathering. As an olivine gabbro cumulate, this meteorite has a bulk composition consistent with derivation from a body that produced a core, mantle, and crust. Also consistent with derivation from a body that produced a core, both fragments of<jats:styled-content style=\"fixed-case\">NWA<\/jats:styled-content>7325 have<jats:styled-content style=\"fixed-case\">HSE<\/jats:styled-content>abundances that are highly depleted compared to bulk chondrites.

The chondritic relative<jats:styled-content style=\"fixed-case\">HSE<\/jats:styled-content>abundances of the fragment characterized by higher<jats:styled-content style=\"fixed-case\">HSE<\/jats:styled-content>abundances most likely reflect the addition of exogenous chondritic material during or after crystallization by surface impacts. The<jats:styled-content style=\"fixed-case\">HSE<\/jats:styled-content>in the other fragment is likely more representative of the parent body crust. One formation model that can broadly account for the<jats:styled-content style=\"fixed-case\">HSE<\/jats:styled-content>abundances in this fragment is multiple episodes of low\u2010pressure metal\u2010silicate equilibration, followed by limited late accretion and mantle homogenization. Given the different<jats:styled-content style=\"fixed-case\">HSE<\/jats:styled-content>compositions of the two adjoining fragments, this meteorite provides an example of the overprint of global processes (differentiation and late accretion) by localized impact contamination.<\/jats:p>","DOI":"10.1111\/maps.13261","type":"journal-article","created":{"date-parts":[[2019,2,26]],"date-time":"2019-02-26T05:22:59Z","timestamp":1551158579000},"page":"1042-1050","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Highly siderophile element and<sup>187<\/sup>Re\u2010<sup>187<\/sup>Os isotopic systematics of ungrouped achondrite Northwest Africa 7325: Evidence for complex planetary processes"],"prefix":"10.1111","volume":"54","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3076-811X","authenticated-orcid":false,"given":"Gregory J.","family":"Archer","sequence":"first","affiliation":[{"name":"Department of Geology University of Maryland College Park Maryland 20742 USA"},{"name":"Institut f\u00fcr Planetologie University of M\u00fcnster M\u00fcnster 48149 Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0348-2407","authenticated-orcid":false,"given":"Richard J.","family":"Walker","sequence":"additional","affiliation":[{"name":"Department of Geology University of Maryland College Park Maryland 20742 USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anthony J.","family":"Irving","sequence":"additional","affiliation":[{"name":"Department of Earth and Space Sciences University of Washington Seattle Washington 98195 USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2019,2,24]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.gca.2013.12.032"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/0016-7037(81)90226-X"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/0009-2541(85)90076-2"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.gca.2015.07.020"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0016-7037(01)00676-7"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.gca.2014.02.046"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1751-908X.1997.tb00528.x"},{"key":"e_1_2_8_9_1","unstructured":"BorisovA.andNachtweyhK.1998.Ru solubility in silicate melts: Experimental results in oxidizing region (abstract #1320). 29th Lunar and Planetary Science Conference.
