Writeup

Writeup from MB 105:

Thiel Mountains 07009 (TIL 07009) 85º9.98’S, 94º33.54’W

Antarctica, Antarctica

Find: 24 Dec 2007

Classification: Enstatite chondrite (EL6)

Petrography: The meteorite consists largely of pyroxene (nearly enstatite) with minor amounts of Fe-Ni metal and sulfides and lesser amount of plagioclase. Chondrules are not discernible.

Geochemistry: Pyroxene composition is Fs_0.3Wo_1.5; Si abundance in Fe-Ni metal is 0.8±0.1 wt%; ferroan alabandite (FeO = 16.1±1.3 wt%). O-isotope composition: δ¹⁷O=2.21‰, δ¹⁸O=4.21‰, Δ¹⁷O=0.00‰, where Δ¹⁷O=δ¹⁷O-0.5248*δ¹⁸O, measured at KOPRI.
