Writeup from AMN 33(2):
Sample Number MIL 091010
Pairing MIL 07403; MIL 07694; MIL 090072; MIL 091010
Newsletter 33,2
Location Miller Range
Field Number 20249
Dimensions 3.0 x 2.0 x 5.75
Weight 51.66
Original Classification CV3 Chondrite
Macroscopic Description - Roger Harrington and Kathleen McBride
30% to 50% of the exteriors of these meteorites are covered with dull black fusion crust. The remaining broken surfaces consists of dark gray fine-grained matrix with 1-2 mm CAI’s scattered throughout. The interiors of these samples are dark to medium gray, fine grained matrix with visible chondrules and numerous 1-2 mm light gray CAI’s.
Thin Section (,2) Description - Corrigan 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 Fa0-43 and low-Ca pyroxene is Fs0-1. The meteorites are unequilibrated carbonaceous chondrites, probably reduced CV3s. These are likely paired with the MIL 07671 pairing group previously reported.

Notes
The meteorite was discovered enclosed in blue ice. The meteorite and enclosed ice were collected as a coherent block and transported to JSC that way, and kept in JSC freezers until April 2010. Ice and meteorite were then transported to the Cold Region Research and Engineering Laboratory (CRREL) in Hanover NH, for extraction of meteorite from the ice using cold room equipment. After removal, the meteorite was transported back to Houston, still frozen, and introduced into the Meteorite Processing Lab. It was thawed and characterized following the standard procedures for the lab, and, of course, is available for study. Samples of the enclosed ice may be available for additional studies if there is interest – please inquire with the JSC Antarctic Meteorite Curation group.
