Writeup from AMN 27(1):

Sample No.:	MET 01322
Location:	Meteorite Hills
Field No.:	13198
Dimensions (cm):	2.8x2.2x0.7
Weight (g):	8.41
Meteorite Type:	L3 Chondrite (Estimated 3.6)

Macroscopic Description: Cecilia Satterwhite
Black/brown fusion crust covers 50 % of the exterior surface. The interior is dark gray to black with abundant clasts. Some as large as ½ cm are visible.

Thin Section (,2 ) Description: Linda Welzenbach, Tim McCoy
The section exhibits numerous large, well-defined chondrules (up to 3 mm) in a matrix of fine-grained silicates, metal and troilite. Weak shock effects are present. Polysynthetically twinned pyroxene is extremely abundant. Olivines range from Fa_13-45; pyroxenes from Fs_1-18. This meteorite contains a fine-grained clast with uniform mineral compositions (Fa₃₂,Fs₂₃). The origin of this clast and its relationship to the host is uncertain, but may be impact-related. The meteorite is a L3 chondrite (estimated subtype 3.6). This meteorite may be paired with the MET 00489 pairing group.
