Here we report the results of a correlated investigation of iron isotope compositions and silicon contents of silicon-bearing metal grains from several aubritic meteorites. Based on their Fe isotopic and elemental Si compositions and thermal modelling, we show that these aubrite metals equilibrated with silicates at temperatures ranging from\u2009~\u20091430 to\u2009~\u20091640 K and likely sampled different depths within their asteroidal parent body. The highest temperature in this range corresponds to their equilibration at a minimum depth of up to\u2009~\u200935 km from the surface of the aubrite parent body, followed by brecciation and excavation by impacts within the first\u2009~\u20094 Myr of Solar System history.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Soumya Ray, Laurence A.
