Writeup from AMN 29(2):
Sample No.: LAP 03822; LAP 03824; LAP 031321
Location: LaPaz Ice Field
Field No.: 16778; 16964; 16649
Dimensions (cm):   1.0x0.5x0.75; 1.0x0.75x0.5; 1.0x0.5x0.5
Weight (g): 1.732; 1.454; 1.309
Meteorite Type: L Chondrite Metal


Macroscopic Description: Kathleen McBride
Exteriors have a brown/black fusion crust with oxidation. All of these appear to have high iron content and resembles metal.


Thin Section (,2) Description: Tim McCoy and Valerie Reynolds
These meteorites are so similar that a single description suffices. All three are cm-sized meteorites comprised of 80-95+% metal displaying Neumann bands and mm-sized inclusions of silicates. The silicates sometimes exhibit relict chondrules. Silicates are homogeneous (Fa24, Fs20). These appear to be anomalously large metal particles separated from an L chondrite.
