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 CAIs 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 CAIs.
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.
