Writeup from AMN 21(2):

Sample No.:	EET96123
Location:	Elephant Moraine
Dimensions (cm):	2.5x2.0x1.0
Weight (g):	8.45
Meteorite Type:	H4 Chondrite

Macroscopic Description: Kathleen McBride
50% of the exterior of this ordinary chondrite has black, bubbly fusion crust with numerous vesicles and dull luster with iridescent oxidation halos. The matrix is very rusty and friable, with numerous yellowish and gray chondrules present. Abundant metal grains are visible.

Thin Section (,2) Description: Tim McCoy

The section is a close-packed aggregate of chondrules (usually less than 1 mm across), chondrule fragments and mineral grains in a dark matrix with abundant metal and troilite. The meteorite is moderately weathered and shocked. Polysynthetically twinned pyroxene is common. Olivine (Fa₁₆) and low Ca pyroxene compositions (Fs₁₄) are below the range typical for H chondrites and similar to a small group of chondrites such as Willaroy (1993, GCA 57, 1867). The meteorite is an unusual H4 chondrite and is almost certainly paired with the EET 96031 pairing group.
