Sample No.: TIL82414 & TIL82415 Location: Thiel Mountains Field No.: 2733 & 2794 Weight (gms): 14.2 & 70.2 Meteorite Type: H5 Chondrite
Physical Description: Roberta Score TIL82414 and TIL82415are covered with weathered fusion crust. The interiors have scattered patches of oxidation in a medium gray colored matrix with small light and dark inclusions. Dimensions: 3 x 2 x 1 cm & 4 x 3 x 2.5 cm
Petrographic Description: Brian Mason Chondritic structure is prominent, but individual chondrules are poorly defined and their margins tend to merge with the granular groundmass, which consists largely of olivine and pyroxene with minor amounts of nickel-iron and troilite. A minor degree of weathering is indicated by brown limonitic staining around metal grains. Microprobe analyses give the following com-positions: olivine, Fa17; pyroxene, Fs15. The meteorite is an H5 chondrite. The sections of these meteorites are very similar in texture and degree of weathering, and the mineral compositions are the same. The possibility of pairing should be considered. | ||||||||||||||||||||
