The exterior is black/brown. The interior reveals a gray/black matrix with lots of rusty areas. Some gray clasts are visible. |
The section consists of a large (1 cm) wide shock vein dominated by fine-grained (2-50 micron grain size) olivine and pyroxene with elongated metal and sulfides cross cutting a chondritic host with chondrules reaching 1mm. The mineral compositions are homogenous; olivine is Fa17 and orthopyroxene is Fs16. The meteorite is a shock-veined H5 chondrite. The section examined may not be a good representative of the mass as whole. It may be paired with LAP 02237. |
