The exteriors are covered with brown/black fusion crust with oxidation halos. The interiors are rusty brown with a brittle texture. |
These sections are so similar that a single description suffices. The meteorites exhibit a microcrystalline silicate matrix including rounded metal-sulfide blebs reaching 20 microns and relict grains, chondrules and clasts reaching up to a few mm. Mafic silicate compositions (Fa19, Fs17) indicate they are of H chondrite parentage and textures suggest they are impact melt breccias. |
