Most of these aubrites have thin patchy brown to yellow fusion crust. All specimens are slightly weathered. Enstatite clasts are as large as 3.5 cm and as small as 1 mm. The clast population ranges from sparse to dense for the different specimens. Dark aphanitic inclusions and metallic inclusions surrounded by oxidation haloes are both common.
