Sample No.: TIL82401 Location: Thiel Mountains Field No.: 2746 Weight (gms): 281.6 Meteorite Type: L6 Chondrite
Physical Description: Carol Schwarz Thin, dull black fusion crust is present on parts of three surfaces of this meteorite fragment. The other surfaces are smooth and reddish-brown. Chondrules (1-6 mm diameter) are visible on the exterior. A wide discontinuous weathering rind was exposed when this stone was chipped, as was fresh gray matrix with a minor amount of oxidation. Dimensions: 6.5 x 5.5 x 6 cm
Petrographic Description: Brian Mason Chondrules are sparse and poorly defined, their margins merging with the granular groundmass, which consists of olivine and pyroxene with minor amounts of plagioclase, troilite, and nickel-iron. Brown limonitic staining surrounds the metal grains. Microprobe analyses give the following compositions: olivine, Fa25; pyroxene, Fs21; plagioclase, An10. The meteorite is an L6 chondrite. | ||||||||||||||||||||
