Petrographic Descriptions (Select a sample)
| Sample No.: | LAP 04689 |
| Location: | LaPaz Ice Field |
| Field No.: | 17633 |
| Dimensions (cm): | 2.0 x 2.0 x 1.5 |
| Weight (g): | 11.242 |
| Meteorite Type: | H5 chondrite |
Macroscopic Description: Kathleen McBride
The exteriors vary from brown/black to brown. The interiors are brittle rusty brown with high metal and fine grained dark gray matrix.
Thin Section (,2) Description: Tim McCoy, Lauren LaCroix and Linda Welzenbach
These meteorites are melt-veined H5 chondrites (Fa19, Fs17) with veins of fine-grained shock melt with small blebs of metal and sulfide. A relationship with the LAP 02240 group is possible, if all of these meteorites represent different proportions of matrix and melt in an impact-melt breccia.
