Sample No.:	LAP 031190; LAP 031379
Location:	LaPaz Ice Field
Field No.:	16611; 16598
Dimensions (cm):	2.5x1.5x1.0; 2.0x1.5x1.25
Weight (g):	4.733; 4.335
Meteorite Type:	Eucrite (Brecciated)

Macroscopic Description: Kathleen McBride
The exterior surface has black/brown fusion crust, shiny on some surfaces, dull on others. The exterior is a gray matrix with little rust and dark gray and white angular clasts.

Thin Section (,2) Description: Tim McCoy and Valerie Reynolds
These meteorites are so similar that a single description suffices. The meteorites are dominated by fine-grained (~200 micron average grain size) basaltic material with patches of interlocking euhedral plagioclase crystals up to 1 mm and basaltic clasts up to 1 mm. Weathering is moderate. Mineral compositions are homogeneous with orthopyroxene (Fs₅₆Wo₃), with lamellae of augite (Fs₂₅Wo₄₃), and plagioclase (An₈₉Or_0.5). The Fe/Mn ratio of the pyroxene is ~29. The meteorites are brecciated eucrites.
