The modal mineralogy, bulk chemistry, magnetic susceptibility, physical properties, and oxygen isotopes of Murrili point to it being an H5 ordinary chondrite. It is heterogeneously shocked (S2\u2013S5), depending on the method used to determine it, although Murrili is not obviously brecciated in texture. Cosmogenic radionuclides yield a cosmic ray exposure age of 6\u20138 Ma, and a pre\u2010atmospheric meteoroid size of 15\u201320 cm in radius. Murrili\u2019s fall and subsequent month\u2010long embedment into the salt lake Kati Thanda significantly altered the whole rock, evident in its M\u00f6ssbauer spectra, and visual inspection of cut sections. Murrili may have experienced minor, but subsequent, impacts after its formation 4475.3 \u00b1 2.3 Ma, which left it heterogeneously shocked.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>S.
