Sample Number LAR 06626
Pairing LAR 06626; LAR 06659
Newsletter 32,2
Location Larkman Nunatak
Field Number 19308
Dimensions 2.5 x 2.5 x 2.0
Weight 22.42
Original Classification EL4 Chondrite
Macroscopic Description - Kathleen McBride
The exterior of 626 has thin black patches of fusion crust; 659 has no fusion crust. The interiors are a dense chocolate brown to black matrix with high metal and some weathered inclusions.
Thin Section (,2) Description - Cari Corrigan, Tim McCoy and Linda Welzenbach
The sections show an aggregate of chondrules (up to 1.5 mm), chondrule fragments, and pyroxene grains in a matrix of about 30% metal and sulfide. Chondrules contain moderate to small abundances of olivine. Weathering is modest, with staining of some enstatite grains and minor alteration of metal and sulfides. Pyroxene is Fs0-2; no olivine grains were analyzed. Metal contains 0.5-0.6 wt% Si. The meteorites are type 4 enstatite chondrites. The Si concentration in metal would suggest classification as EL4. Pairing is tentative.
