Writeup from AMN 17(1):
Sample No.: DAV92302; 92306 Location: David Glacier Dimensions (cm): 5.5 x 3.0 x 2.0; 1.5 x 1.0 x 0.8 Weight (g): 58.8; 1.6 Meteorite Type: LL3.6 chondrite
Macroscopic Description: Carol Schwartz Both specimens are angular-shaped with thin weathered fusion crust. DAV92302, the larger specimen, has an interior of medium gray matrix which is moderately weathered. Less than 2 mm light-colored inclusions are abundant. This is a very coherent meteorite. DAV92306 also has a gray interior with dark and light colored inclusions and is less weathered.
Thin Section (DAV92302,2; 92306,2) Description: Brian Mason The sections are so similar that a single description will suffice; the meteorites are probably paired. They show a closed-packed aggregate of chondrules and chondrule fragments, up to 2.4 mm across, in a small amount of dark matrix which includes a few grains of nickel-iron and troilite. Weathering is extensive, with brown limonitic staining throughout the sections. Microprobe analyses show olivine and pyroxene of variable composition: olivine, Fa11-32; pyroxene, Fs4-18. The meteorite is classified as an LL3 chondrite (estimate LL3.6).
