| Newsletter | 01-2 |
| Location | California, USA |
| Thin-section ID Number | V071 |
| Dimensions | 4.5cm x 4cm x 3.5cm |
| Weight | 121.4 grams |
| Type Specimen | 27 gram endcut - plus thin-section |
| Class | Ordinary Chondrite |
| high (very likely above "W3") | |
| low (most likely "S2" or lower) | |
| Macroscopic Description -- R. Verish | |
| The dark, grayish-brown exterior of this chondrite has no fusion crust. In fact, several chondrules are quite visible, standing in high relief, suggesting that the groundmass is not very resistant to weathering.The interior is a dark-brown, porous matrix with low metal-grain content and the chondrules and inclusions are quite variable in size. | |
| Thin Section Description -- R. Verish | |
| The section exhibits a variety of chondule sizes (some up to 3 mm), and most are somewhat-defined in a dark-brown, iron oxide-rich matrix of fine-grained silicates, troilite and rare metal. The meteorite is highly weathered. Very weak mosaic shock effects are present. Silicates are equilibrated. This meteorite is probably a low-shock, equilbrated H-chondrite. | |
