The exterior has fractured black fusion crust with some oxidation. The interior is light gray with some darker gray heavily weathered areas along the edges. Some metal is visible. | |
Thin Section Description (,2) - Linda Welzenbach, Pamela Salyer, Tim McCoy | |
The section exhibits two textures; one side is a fine-grained, melt-textured matrix of olivine and pyroxene (1-10 microns) with fragments of mineral grains (200-300 micron grain size) and the other, chondrules and chondrule fragments with abundant fractures. The mineral compositions are slightly unequilibrated; olivine is Fa17-28 and pyroxene is Fs7-22. The meteorite is an LL chondrite impact melt. |
