Sample Number	MIL 07368
Pairing	MIL 07182; MIL 07265; MIL 07368; MIL 07546; MIL 07688; MIL 07695
Newsletter	33,1
Location	Miller Range
Field Number	18617
Dimensions	1.25 x 1.0 x 0.75
Weight	2.010
Original Classification	CO3 Chondrites
Macroscopic Description - Kathleen McBride, Roger Harrington and Cecilia Satterwhite
All of these carbonaceous chondrites have black fusion crust covering 50 to100% of the exterior surface. The interiors are fine grained, dark gray to black matrix with some rust and oxidation near the edges. Tiny white inclusions are visible, some are rusty.
Thin Section (,2) Description - Cari Corrigan, Tim McCoy and Linda Welzenbach
These meteorites are so similar that a single description suffices. The sections consist of abundant small (up to 1 mm) chondrules, chondrule fragments, and mineral grains in a dark matrix. Metal and sulfide occur within and rimming the chondrules. Olivine ranges in composition from Fa_0-73. Pyroxene analyses range from Fs_1-17. These meteorites are CO3 chondrites and are probably members of the MIL 07531 pairing group.
