Writeup from AMN 4(2):

Sample No.: ALHA80105

Location: Allan Hills

Field No.: 1066

Weight (gms): 445.1

Meteorite Type: L6 Chondrite


Physical Description: Carol Schwarz

This sample is not a complete specimen. It has no fusion crust except for 2 or 3 small spots that may be remnant fusion crust. Some ~3 mm chondrules are visible. Several linear fractures which are heavily weathered are present and are similar to those in ALHA80101 and 80103. The interior is gray with oxidation halos and metal flecks. A discontinuous 2 mm thick weathering rind is present. Dimensions: 12 x 6.5 x 3.5 cm.


Petrographic Description: Brian Mason

Polished thin sections of ALHA80103, 80105 are identical in texture, mineral compositions, and degree of weathering with ALHA80101, indicating that these three specimens are pieces of a single meteorite.
