Antarctica

Found 2003

Carbonaceous chondrite (CO3)

The fragment weighs 6.57 g, with a few of fusion crust remains. Classification and Mineralogy (CAS): Chondrules are small and have a bimodal size distribution, with one peak at 30-100 μm and the other at 350-600 μm in diameter. Modal abundance ratio of chondrule to opaque matrix is 1.2. Fe-Ni metal and sulfide are rare. Ca-Al-rich inclusions were found, and they are strongly altered. Silicates are highly heterogeneous: olivine, Fa18.8±20; low-Ca pyroxene, Fs7.0±12. Shock stage, S1; weathering grade, W1.
