Writeup from AMN 5(1):

Sample No.: ALHA80108

Location: Allan Hills

Field No.: 1094

Weight (gms): 124.5

Meteorite Type: L6 Chondrite


Physical Description: Carol Schwarz

The sample has no fusion crust. It is rough and weathered reddish brown and is similar to ALHA80101. Some light colored chondrules or clasts are visible. Chipping revealed a light gray interior with some oxidation halos and a dark gray weathering rind. Dimensions: 7 x 5 x 3.5 cm


Petrographic Description: Brian Mason

The physical description indicated that this specimen may be paired with ALHA80101, and this is confirmed by the microscopic examination, which shows that it is an L6 chondrite identical with that meteorite in texture, mineral compositions, and degree of weathering.
