Sample No.:	LAR 06875
Location:	Larkman Nunatak
Field No.:	19328
Dimensions (cm):	6.0 x 5.5 x 3.0
Weight (g):	165.797
Meteorite Type:	Eucrite (Brecciated)

Macroscopic Description: Kathleen McBride
Black and dark gray patches of various sizes of what appears to be fusion crust is present on the exterior. The dull, marbled appearing interior consists of cream and dark gray materials. Individual clasts are not distinct. Fines are rather powdery and weathered.

 

Thin Section (,2) Description: Tim McCoy, Lauren LaCroix and Linda Welzenbach
This meteorite is dominated by fine-grained (~100 micron average grain size) basaltic material which occurs as both the host and clasts within this meteorite. In parts, the section has a cataclastic, rather than brecciated, appearance. Occasional coarser-grained clasts (grain sizes up to 0.2 mm) are observed. Mineral compositions are homogeneous with orthopyroxene (Fs₆₁Wo₂), augite (Fs₂₇Wo₄₃), and plagioclase (An₈₆Or_0.5). The Fe/Mn ratio of the pyroxene is ~30. The meteorite is a brecciated eucrite.
