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.
