Sample No.:	LAP 04841
Location:	LaPaz Ice Field
Field No.:	17462
Dimensions (cm):	5.0x2.5x2.5
Weight (g):	55.992
Meteorite Type:	Lunar-Basalt

Macroscopic Description: Kathleen McBride
Dull, black fusion crust covers over 50% of the exterior. Some surfaces have shiny areas. The interior is a pinkish tan and white matrix with black glass filled veins.

Thin Section (,4) Description: Valerie Reynolds, Tim McCoy and Linda Welzenbach
The meteorite is almost certainly paired with the LAP 02205 pairing group. LAP 02205 was described as follows: The section consists of coarse-grained unbrecciated basalt with elongate pyroxene (up to 0.5 mm) and plagioclase laths (up to 1 mm) (~60:40 px:plag), rare phenocrysts of olivine (up to 1 mm) and interstitial oxides and late-stage mesostasis. Shock effects include undulatory extinction in pyroxene and shock melt veins and pockets. Microprobe analyses reveal pigeonite to augite of Fs_26-80Wo_14-36, plagioclase is An_85-90Or_0-1 and a single olivine phenocryst is Fa₅₀. The Fe/Mn ratio in the pyroxenes averages ~60. The meteorite is a lunar olivine-bearing basalt.
