| Location | Nevada, USA |
| Thin-section ID Number | V009 |
| Dimensions | 4.cm x 3cm x 2.5cm |
| Weight | 29.5 grams |
| Type Specimen | 7.4 gram endcut - plus thin-section |
| Class | Ordinary Chondrite |
| high (very likely above "W3") | |
| low (most likely "S2" or lower) | |
| Macroscopic Description -- R. Verish | |
| This fragment of a chondrite has a relict fusion crust. A cut surface shows that the interior is brecciated; clasts have a yellowish-brown matrix with chondrules and inclusions that are small, and a modest metal-grain content. Clasts are surrounded by narrow, dark-brown melt-veins. | |
| Thin Section Description -- R. Verish | |
| The section exhibits a brecciated pattern having clasts with small chondules, and most are poorly-defined in a light-brown groundmass of fine-grained silicates, troilite and rare metal. The meteorite is weathered. Mosaic shock effects are present. Silicates are equilibrated. This meteorite is probably a high-shock, equilbrated H-chondrite. | |
