Writeup from AMN 7(1):
Sample No.: TIL82402 Location: Thiel Mountains Field No.: 2735 `eight (gms): 476.0 Meteorite Type: LL6 Chondrite
Physical Description: Roberta Score Black fusion crust covers all but the edges of this square meteorite. Light gray matrix with dark and light inclusions (chondrules?) make up the interior of TIL82402. Dimensions: 7 x 6 x 6 cm
Petrographic Description: Brian Mason Chondrules are sparse and poorly developed, tending to merge with the granular groundmass, which consists largely of olivine and pyroxene, with minor amounts of plagioclase and troilite, and a little (ca. 2%) nickel-iron. The section shows a brecciated structure, with medium- to fine-grained clasts. Weathering is minor, being limited to a little brown limonitic staining around metal grains. Microprobe analyses give the following compositions: olivine, Fa29; pyroxene, Fs24; plagioclase, An10. The meteorite is an LL6 chondrite. | ||||||||||||||||||||
