Writeup from MB 103:

Thiel Mountains 07003 (TIL 07003)        85°09.43’S, 94°36.39’W

Antarctica

Found: 2007 Dec 24

Classification: Carbonaceous chondrite (CV3)

Physical characteristics: The stone is almost completely covered with dark-black fusion crust; the interior is relatively fresh.

Petrography: The rock consists of chondrules (~64 vol.%), AOAs (~2 vol.%), one large CAI (~3 vol.%) and fine grained matrix (~ 31 vol%). Chondrules, AOAs the CAI are elongated and aligned in the same direction and numerous micro-faults are present. Opaque minerals are Fe-Ni metal and troilite; no magnetite was found in the section. The petrographic characteristics are very similar to TIL 07007. Chondrules are mostly type-I PO or POP chondrules and many of them were surrounded by coarse-grained igneous rims. Typical sizes of the chondrules are 0.89 mm × 0.58 mm. One CAI (2.78 mm × 0.94 mm) in the section mostly consist of melilite, spinel and Al-diopside. AOAs mainly consist of olivine (Fa content <2.6 %) with minor amount of melilite and Al-Ti-diopside.

Geochemistry: Olivine: Fa0.3-5.7 (av. Fa1.1). Low-Ca pyroxene: Fs0.6-3.1Wo0.3-3.3 (av. Fs1.2Wo1.5). High-Ca pyroxene: Fs0.3Wo47.4. Melilite in CAI: Ak content from 9.8 to 20.5.
