Name: Miller Range 07678 This is an OFFICIAL meteorite name. Abbreviation: MIL 07678 Observed fall: No Year found: 2007 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 7.7 g
Macroscopic Description - Kathleen McBride and Roger Harrington
The exteriors of these carbonaceous chondrites have brown/black fusion crust with polygonal fractures. The interiors of these meteorites have dark gray to black matrixes with some weathered areas. Most have white and light gray chondrules and inclusions. 07669 has mint green colored evaporates over half of its surface.
Thin Section
(,2)
Description - Cari Corrigan, Tim McCoy and Linda Welzenbach
The sections are so similar that a single description suffices. The sections exhibit large chondrules (up to 3 mm) and CAIs in a dark matrix. Olivines range from Fa0-64 and low-Ca pyroxene is Fs1-5. The meteorites are unequilibrated carbonaceous chondrites, probably reduced CV3. These are likely paired with the MIL 07671 pairing group previously reported. Pairing of MIL 07690 and MIL 07683 is considered tentative, as the former is dominated by fusion crust and the latter, while similar to other members of the group, lacks metal grains in the thin section examined.
