| Newsletter | 01-2 |
| Location | Arizona, USA |
| Thin-section ID Number | RSV062 |
| Dimensions | 3.0cm x 2.4cm x 1.5cm |
| Weight | 35.85 grams |
| Type Specimen | 9.85 grams - endcut |
| Class | Ordinary Chondrite |
| high (very likely above "W4") | |
| low (most likely below "S3") | |
| Macroscopic Description -- R. Verish | |
| The exterior of this ordinary chondrite has dark-brown, relict fusion crust. The interior is a dark brown matrix with low metal content and the chondrules and inclusions are small and indistinct. | |
| Thin Section Description -- R. Verish | |
| The section exhibits a variety of chondule sizes (but only up to 2 mm), and nearly all are poorly-defined in a dark grayish-brown matrix of fine-grained silicates, troilite and rare metal. The meteorite is highly weathered. Very weak mosaic shock effects are present. Silicates are equilibrated (plagioclase grains average 40 µm in size). This meteorite is probably an equilbrated H-chondrite. | |
