The exteriors of these meteorites are covered with brown/black fusion crust with oxidation haloes. The interiors are a fine-grained, rusty, crystalline material with some metal.
The meteorites are so similar that a single description suffices. The sections consist of an equigranular aggregate with grains up to 0.5 mm. Minerals include olivine (Fa₈₋₉), orthopyroxene (Fs₉), chromian diopside (Fs₃₋₄Wo₄₄₋₄₅), phosphates, metal and troilite. Metal and sulfide occur as large grains, veinlets and metal-sulfide blebs within orthopyroxene. Weathering is moderate, with extensive staining. The meteorites are acapulcoites.
